What does the line at 13600 represent?
scale bar
index contour
elevation difference
topographic symbol
Answer:
Index contour
Explanation:
A line on a map at 13600 would likely represent an index contour. On a topographic map, an index contour is a contour which is usually thicker and bolder with its elevation value written on it. Using this index contour and the contour intervals, we can estimate the values of other contour lines on the map.
The use of an index contour makes the map less crowded with symbols thereby making the map readable.
The answer is index contour, or the second option.

What are examples of constructive and destructive forces?
There's multiple natural forces that are considered constructive or destructive. Constructive forces can be the volcanic eruptions, deposition, the deformation of the crust, while destructive forces can be the erosion and the weathering. The constructive forces are the the natural forces that manage to build up and create the landforms, while the destructive forces are the ones that manage to destroy the landforms. In general, the constructive forces are building up, thus making the surface more ragged, creating faults, hills, mountains, valleys. On the other hand, the destructive forces have the tendency to flatten the surface of the Earth, and they practically destroy little by little the landforms created by the constructive forces until they level them up.
Which two factors cause the perpendicular rays of the sun to move between 23.5o n and 23.5o s?
Answer:
It is the tilt of Earth's axis and Earth's rotation.
Explanation:
Both tilt and rotation are required for the perpendicular rays to move.
Final answer:
The movement of the sun's perpendicular rays between 23.5° N and S is caused by the Earth's axial tilt of 23.5 degrees and its elliptical orbit as per Kepler's Second Law, leading to the seasonal variations experienced on Earth.
Explanation:
The two factors that cause the perpendicular rays of the sun to move between 23.5° N and 23.5° S are the Earth's axial tilt and its elliptical orbit around the sun, which are also the basis of the seasonal changes we experience. The axial tilt of 23.5 degrees means that different parts of the Earth are closer or farther from the sun at different times of the year, leading to the Tropic of Cancer (23.5° N) and the Tropic of Capricorn (23.5° S) experiencing the sun's rays perpendicularly at the summer and winter solstices, respectively. Furthermore, the Second Law of Kepler, which states that a planet moves about the sun at such rates that the line connecting the centers sweeps over equal areas in equal times, contributes to the slight variations in the speed of Earth's orbit, affecting the exact positioning of the sun's perpendicular rays throughout the year.
which of the following is not a form of political participation
You have to show us the political participation
The correct answer is C) paying taxes.
The other options of the question were A) voting in elections. B) contacting public officials. D) protesting government decisions.
Paying taxes is not a form of political participation.
Political participation is when you actively participate and write to your representatives to ask or demand a solution to a problem. That is why you voted for them. And you follow up on your petition. If nothing happens, you organize demonstrations, go to TV stations, send comments to radio stations or took the streets to protest and make your voice heard.
Paying taxes is your obligation as a citizen. It is not considered to be political participation.
Brittany wants to use a model to study soil erosion on hills. She is told that farmers can prevent soil erosion by plowing so that their furrows run along hills instead of up or down hills. She fills a pan with dirt, packs the dirt firmly, then shapes it into parallel furrows. What should Brittany do with her pan of dirt next in order to study soil erosion? A. shake the pan rapidly back and forth B. prop up one end of it to make a slope and carefully pour water over it C. fill the pan with water, then tilt it until all the water runs out D. set it outside and check on it every day
Answer:
D. set it outside and check on it every day
Explanation:
In order for Brittany to be able to study the soil erosion by using a simplified method of what the farmers do on the slopes to minimize it, she will need to take the pan, leave it outside, and check on it every day. By having the required shape, the soil will give somewhat an example of the soil on the slopes that has been plowed so that the furrows run along the hills. Since the hills do not move or tilt, the pan with the soil should be stable, static. Being put outside, it will be exposed to the natural conditions that cause the erosion, such as the water and wind. Brittany will need to check upon the soil every day and make detailed notes and measurements to see what the erosive effects are on it.

Does the earth have an unlimited supply of magma?
Answer:
No
Explanation:
The magma supply of the Earth is not unlimited, but instead it has a fairly constant volume. On the other hand, the magma is not spending itself even though it constantly comes out on the surface of the Earth. The reason for that is that the magma that comes out on the surface, is actually replaced by newly formed magma. The newly formed magma is actually from the crust of the tectonic plates that are subducting. As the plates are subducting, they reach the mantle layer where the temperature and pressure are very high, so they melt the crust. The molten crust is becoming the new magma that replaces the one that is pushed toward the surface. This is a cycle that constantly goes on, so even though the magma is not endless, it manages to circle through the top two layers and replenish itself.
What motivates many South Americans to move from rural to urban areas?
irrigation
the fact that mechanized agriculture has replaced manual labor
plantation farming
subsistence agriculture
Final answer:
The main motivation for South Americans moving from rural to urban areas is the search for better economic opportunities due to the replacement of manual farm labor by mechanized agriculture. Urban areas offer more jobs, education, and healthcare, while farming presents challenges like weather dependence and unstable markets.
Explanation:
Many South Americans are motivated to move from rural to urban areas primarily due to the promise of better economic opportunities. Mechanized agriculture has replaced much of the manual labor on farms, resulting in fewer job opportunities in rural areas. As a result, people often seek work in urban areas where industries and services provide more employment options. Furthermore, urban areas tend to offer better access to education, healthcare, and infrastructure. The challenges of farming, such as dependency on weather and volatile market prices, also make agricultural life less attractive, prompting a rural-to-urban migration. This historical trend of urbanization mirrors the global shift seen since the Industrial Revolution, where technological advancements and industrial growth have concentrated populations into growing cities.
A student wants to know if the bubbles on this water plant are oxygen gas
(02). However, identifying a gas as O2 with direct evidence requires many
kinds of equipment.
Which observation would provide indirect evidence that the bubbles are 0?
O
A. A measurement of the plant's growth over time
O
B. A description of the color of the light under which the plant is
growing
O
C. A description of the shape of the plant's leaves
D. A count of the number of bubbles produced by the plant in the
dark
Answer:
D
Explanation:
Plants produce oxygen as a byproduct of photosynthesis; The formulae for photosynthesis is; 6CO2 + 6H2O –(sunlight)----> C6H12O6 + 6O2
Therefore for oxygen to be produced, there has to be sunlight. An indirect way of determinig the gas is comparing the number of bubbles during the day and night. The bubbles should be more during the day than night.
In order to indirectly confirm that the observed bubbles on the water plant are oxygen, one could measure the amount of bubbles produced by the plant in dark conditions. If there's a significant decrease in bubble production in the dark, it suggests that the bubbles produced in light are oxygen, a byproduct of photosynthesis.
Explanation:The observed bubbles on the water plant could potentially be oxygen (O2) as a product of photosynthesis. In general, during photosynthesis, plants convert carbon dioxide and water into glucose and oxygen using light energy. Therefore, observing the bubbles in water around a plant can be indirect evidence of O2 production if the conditions for photosynthesis are present.
The ideal observation would be to count the number of bubbles produced by the plant in the dark (Option D). This is because photosynthesis — the process by which plants convert light energy into chemical energy, producing glucose and releasing oxygen as a byproduct — doesn't happen in the absence of light. Therefore, if there's a significant decrease or complete absence of bubble formation in the dark, it would indirectly suggest that the bubbles being observed under light conditions are indeed oxygen, released during photosynthesis.

What is the capital of the united states largest state
Answer:
Juneau
Explanation:
The largest state in the United States is Alaska. The capital of this detached state is Juneau. Juneau has been the capital of Alaska since the beginning of the 20th century, more specifically from 1906. This city is actually not the biggest in Alaska, but instead it is the second largest, though it is a center of large portion of the things that happen in the state. The population of the city itself is little over 32,000 people, making it the least populous capital city of any state in the United States. As a metropolitan area though, the population is around 100,000 people. It can not really be expected for this city to be much larger as the climate and the geography simply don't provide the conditions for big growth.

Air masses are identified on the basis of temperature and?
A) type of precipitation
B) wind velocity
C) moisture content
D) atmospheric transparency
moisture content
Answer is C)
Final answer:
Air masses are classified by temperature and moisture content; the correct answer is C) moisture content. They are designated as 'm' for maritime and 'c' for continental based on their humidity, and by other symbols for temperature origins, such as 'A' for arctic or 'T' for tropical.
Explanation:
Air masses are identified on the basis of temperature and moisture content. Moisture content is critical because air masses absorb moisture when they are over bodies of water, thus becoming more humid, and they lose moisture when they are over land, leading to drier conditions. The temperature of an air mass is influenced by its latitude of origin - polar regions produce colder air masses, while tropical regions generate warmer ones.
The correct answer to the question is thus C) moisture content, as air masses are broadly characterized by both their temperature and their moisture levels. These characteristics are integral to the classification of air masses, as they determine the type of weather they will bring to an area. The letter code system designates wet air masses as 'm' for maritime and dry air masses as 'c' for continental, along with other temperature-based symbols like 'A' for arctic and 'T' for tropical.
Changes in both temperature and moisture content as air masses move from their source regions can lead to modifications in the weather patterns of the areas they move over. Understanding these properties is essential for predicting weather conditions and climate variations.
What three processes happen in every geological period? A. Mass extinctions, Wegenerian cycles, and the emergence of new life forms B. Climate change, Wegenerian cycles, and mass extinctions C. Mass extinctions, the complexity of life, and oceanic movement D. Wegenerian cycles, massive storms, and continent formation
Answer:
A. Mass extinctions, Wegenerian cycles, and the emergence of new life forms
Explanation:
Every geological period is characterised by episodes of mass extinction, Wegenerian cycles and emergence of new life forms.
The boundaries of most geologic periods are usually mass extinction periods and these mass extinction activates new evolution of life forms. For example, the period between the Mesozoic era and Cenozoic is marked by the K-T extinction where dinosaurs and about 75% of all life became extinct. New advanced mammals sprang up shortly after the extinction in the Cenozoic era.
During the geologic period, series of tectonic activities are in play as a result of the internal workings of the earth. Continents splits apart and new landform arises at plate boundaries. This is the Wegenerian cycle. The external processes like weathering and erosion helps to recycle the landforms and keeps it in check.

Are there more mountains east or west of the mississippi river
Answer:
yesExplanation:
There is only one major mountain range east of the Mississippi River (the Appalachians) but two major ranges west ( the Rockies and the Sierra Nevadas). The latter mountain ranges are relatively younger than the Appalachians and therefore have higher and sharper (and more) peaks.
The United States has more mountains to the west of the Mississippi River, including notable ranges like the Rocky Mountains and the Sierra Nevada. Comparatively, the East has fewer mountains, although it includes ranges like the Appalachian Mountains.
Explanation:The Mississippi River divides the United States into the East and West. Generally, there are more mountain ranges located to the West of the Mississippi River. Significant mountain ranges such as the Rocky Mountains and the Sierra Nevada contribute to this count. Although there are mountains to the east, such as the Appalachian Mountains, their count is not as abundant as the West.

What do you need in order for an igneous rock to form
For an igneous rock to form, volcanism must be involved.
Igneous rocks are generally divided into two types: intrusive igneous rock and extrusive igneous rocks.
Intrusive igneous rock is where intrusive volcanism take place and the magma below surface cools down to form rock. One example is granite.
Extrusive igneous rock is formed where extrusive volcanism take place, the lava cools down to form rocks such as basalt and tuff.
Hope it helps!
Igneous rocks form from the cooling and solidification of magma or lava. The process requires magma or lava, a cooling process, and a mineral composition. The rate of cooling and the mineral composition determine the texture and type of igneous rock formed.
Explanation:Igneous rocks form from the cooling and solidification of molten rock material, known as magma or lava. For an igneous rock to form, there are three essential components needed:
Magma or lava: This is the molten rock material that cools and solidifies. Magma is found beneath Earth's surface, while lava is expelled onto the surface during volcanic eruptions. Cooling process: The magma or lava must cool down to form solid rock. The rate of cooling determines the texture of the resulting igneous rock. Slow cooling allows for the growth of large mineral crystals, resulting in coarse-grained rocks, while rapid cooling leads to the formation of small mineral crystals, producing fine-grained rocks. Mineral composition: The minerals present in the magma or lava determine the type of igneous rock that forms. Different minerals have different chemical compositions, which influence the characteristics of the resulting rock. Learn more about Igneous rock formation here:

What is the island in the atlantic off the northwestern coast of mainland europe?
The British Isles are an archipelago (Great Britain and Ireland, and other smaller islands) located at the northwest of the coast of Europe. They are separated from the European continent by the North Sea to the east and by the English Channel to the south, while to the west and north they border the Atlantic Ocean.
However this was not always in this way. Millions of years ago this portion of land was a peninsula linked by a limestone mountainous ridge to mainland Europe. This is how, where the current Dover Strait is located, there was a rock formation that joint Great Britain and France.
It is estimated that it was at the end of the last Ice Age (this whole area was frozen and the sea level was far much lower than today) that this territory began to separate from the continent, a process that ended in the Mesolithic period, in the middle of the Stone Age, becoming the insular territory we know today.
In fact, the current Irish Sea and the North Sea were dry land that was submerged with the rise of sea level in the thaw.
