The earth is about 4.6 billion years old, but the oldest ocean floor is only about 200 million years. how do you explain this?

Answer:

Echo Sounding

Explanation:

It's the key method scientists use to map the seafloor today. The technique was first used by German scientists in the early 20th century.

The answer is D. Gray or brown particles that cloud the air

Answer:The answer is D. Gray or brown particles that cloud the air

Explanation:

The correct answer is - world's highest navigable lake.

Titicaca is one of the largest lakes in South America. It is high in the Andes Mountains, and has a surface elevation of 3,812 meters above sea level. The lake is located on the border between the countries of Peru and Bolivia. This lake is the highest navigable body of water on the whole planet, and is widely used by the locals for multiple purposes.

This lake is known as the lake where the Inca civilizations started off, and all around it there's numerous archaeological sites of the Incas. One of its trademarks is the very calm and seemingly still waters, as well as being very brightly reflective.

The characteristic of magma that does NOT determine the type of volcano is option (d) Depth of origin. So, the correct option is d.

While the other three characteristics – viscosity, temperature, and composition – play significant roles in determining the type of volcano, the depth of origin does not directly influence volcano type. Viscosity, or the magma's resistance to flow, affects the eruptive behavior, with more viscous magmas typically leading to explosive eruptions characteristic of stratovolcanoes.

Temperature influences magma density and behavior, with hotter magmas generally being less viscous and more likely to produce effusive eruptions associated with shield volcanoes. Composition refers to the chemical makeup of the magma, which varies based on the minerals and gases present, impacting eruption style and resulting landforms.

However, the depth of origin, while influencing other characteristics like temperature, is not a primary determinant of volcano type. Instead, it is more relevant to magma formation and movement within the Earth's crust. So, the correct option is d.

complete question:

Which of the following characteristics of magma does NOT determine the type of volcano?

a) Viscosity

b) Temperature

c) Composition

d) Depth of origin

Answer:

The Great Plains are the driest.

Explanation:

All the others (Central Lowland, Interior Lowland, Superior Uplands) have some sort of water source to keep them somewhat wet.

I would love to say it's false but sadly it isn't. The Greeks knew of the daily rotation of earth and the revolution about the sun. They computed the diameter of the earth to near exactness.

The statement is primarily true as most earthquakes and volcanic eruptions occur along plate boundaries; however, exceptions exist. Notable examples include volcanic activities in Hawaii and seismic events in places like the New Madrid Seismic Zone, which occur away from plate boundaries.

True or False: Earthquakes and volcanic eruptions always occur along plate boundaries. The statement is primarily true, but some exceptions do exist. Primarily, earthquakes and volcanic eruptions take place along plate boundaries as this is where tectonic activity is typically the highest. These boundaries, where plates meet, are areas subject to immense geological forces that can lead to seismic and volcanic activities. This is illustrated by well-known disaster-prone areas such as the Pacific Ring of Fire. However, it should be noted that there are instances where such events occur away from plate boundaries due to local geologic conditions. For example, the volcanic activities in Hawaii and seismic events in the New Madrid Seismic Zone.

Answer: to export more than they import

Answer:

When governments seek a favorable trade balance, they want to export more than they import.

Explanation:

    Trade balance is an economic term that represents imports and exports of goods between countries. We say that a country's trade balance is favorable when it exports (sells to other countries) more than it imports (buys from other countries).

    The favorable trade balance has advantages for a country, as it attracts foreign currency and generates jobs within the exporting country.

Landforms are commonly classified based on their physical features, characteristics, and how they were formed. Other factors such as size, location, and geological history can also be used to classify landforms.

Exogenic and endogenic forces work together to create landforms. landslides, volcanoes, earthquakes, and other sudden events are examples of endogenic forces. Exogenic forces: Glaciers, wind, water, and sea waves all contributed to the erosive and depositional landforms that are seen today.

Mountains are steep, elevated landforms that rise above surrounding areas due to tectonic activity, erosion, or volcanic activity. Plateaus: flat, elevated areas of land that are higher than the surrounding areas, often with steep sides. Hills: elevated areas of land that are lower and less steep than mountains, often rounded or conical in shape.

Valleys: low areas of land between hills or mountains, often formed by erosion or water. Plains: flat or gently rolling areas of land that are lower than surrounding areas, often formed by sediment deposition.

Deserts: dry, barren regions of land with little vegetation, often characterized by extreme temperatures and low precipitation.

Explanation:

Answer:

A. It is located in areas with tropical, rainy climates.

The grassland biome is usually located in areas with dry and continental climates. Grasslands are often located in the interior of the Earth’s continents. They usually have dry weather, and the weather can be extreme (hot summers and cold winters). The plants in this biome often include grasses and smaller trees. Animals in the grassland biome have adapted to handle extreme climates and plenty of sun.

Answer:

A. One unit on the map is equal to 24,000 units on the ground

Explanation:

A map scale of 1:24,000 means that each unit on the map equals 24,000 of those same units on the ground in reality. This scale is a ratio of distance and does not relate to contour intervals. If you measured a distance of 1 inch on the map, it would be approximately 2000 feet in the real world.

When we talk about a map scale of 1:24,000, it means that one unit (whether that be an inch, centimeter, etc.) on the map equates to 24,000 of those same units on the actual ground. This is a representation of the ratio of distance and helps us understand how distances on the map translate to real-world distances. For instance, if you measured a distance of 1 inch on the map, it would correspond to 24,000 inches (or approximately 2000 feet) in the real world. Note, this scale has nothing to do with the contour interval of the map, nor does it mean that one unit on the ground would be represented by 24,000 units on the map.
