Mount St. Helens in Washington State erupted in 2004 and did not quiet again until 2006. Here are some of the observations scientists recorded in the fall of 2004.

Sept. 23-25: Earthquakes began, too small to be felt by most people at first.

Sept. 29: Scientists observed that deformation—a slight change of shape—had taken place on part of the crater floor.

Oct. 1: Steam, ash, and gases started escaping from the volcano.

Oct. 2: The first long, continuous tremor occurred.

Oct. 4: The bottom of the crater floor rose by tens of meters.

Oct. 7: The volcano was emitting gas at a rate of 2,400 tons per day of CO2, 100 tons per day of sulfur dioxide, and 10 tons per day of H2S.

Oct. 11: The first magma reached the surface.

How is information like the above being used to protect people from volcanoes?

A.

Scientists monitor active volcanoes so that they can relieve the pressure in them before the volcano is forced to erupt.

B.

Scientists use the data collected to learn how eruptions work so that they can prevent all deaths and property damage due to lava and ash.

C.

Scientists monitor active volcanoes for signs the the volcano is going to erupt in order to evacuate threatened areas in time.

D.

Scientists use the data collected to learn how volcanoes work so that they can prevent or delay eruptions.

how would a collapsing universe affect light emitted from clusters and superclusters?


please and thanks!

Answers

Answer:

When a universe collapses, clusters of stars start to move towards each other.

This then results in the Light acquiring a blueshift.

A collapsing universe would cause a gravitational blue shift in light from clusters and superclusters, making it appear bluer and more energetic. The immense gravitational forces would further bend and alter the light's path. Increased density during collapse would intensify these effects.

A collapsing universe would have significant effects on light emitted from clusters and superclusters of galaxies. Normally, due to the expansion of the universe, light experiences a cosmological redshift, where the wavelength of light is 'stretched' and appears redder to an observer. However, in a collapsing universe scenario, the opposite would occur.

Here's the step-by-step explanation:

Gravitational Blue Shift: As the universe collapses, space contracts, and light waves are compressed. This would cause a gravitational blue shift where the wavelength of light shortens, making it appear bluer and more energetic.Influence of Gravity: The immense gravitational forces from galaxy clusters and superclusters would additionally alter the light's path. This effect, akin to gravitational lensing, might bend the light or even create multiple images of the same light source.Increased Density: With the universe collapsing, the density of matter becomes higher. This increased density would further intensify the gravitational blue shift as light would interact more with the denser gravitational fields.

In conclusion, a collapsing universe would shift the light from clusters and superclusters towards the blue end of the spectrum due to gravitational blue shift, altering our observations of these celestial bodies significantly.

a pole that is 2.9 M tall casts a shadow that is 1.56 M long at the same time a nearby Tower casts a shadow that is 40.25 meters long how tall is the tower round your answer to the nearest meter​

Answers

Answer:

h = 74.823 m

Explanation:

given data

pole  tall = 2.9 M

shadow  long =  1.56 M

Tower shadow = 40.25 meters

solution

we get here tower height that is h

so as per given image below

we could see two similar triangles.

Similar triangles have sides proportional

tan θ = [tex]\frac{2.9}{1.56} = \frac{h}{40.25}[/tex]    

h = 74.823 m

Which are evidence of sea floor spreading? Select three options.

Answers

Answer:

Several types of evidence supported Hess's theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves.

Explanation:

Sea-floor spreading occurs when the sea floor spreads apart along divergent boundaries and forms the mid-ocean ridge. Magma is pushed up through cracks in the crust along the mid-ocean ridge. As the magma is thrust up and hardens it forms new crust and the ocean floor on both sides of the mid-ocean ridge move outward.

Which major type of air mass is moving into the area

Answers

Answer: B. continental polar

Explanation:

The large air mass that is moving into the area is a continental polar one. As we can see on the map, the air mass is moving in from the northern part of North America toward the Central part of North America. It is an air mass that has been formed over land, thus it is a continental one, and since it has been formed on a very high latitude it is a polar one too. This type of air mass brings in very cold weather, often resulting in large amounts of snowfall as well, thus it is causing severe snow storms.

Continental polar major type of air mass is moving into the area. Air masses in the continental poles and arctic are cold, dry, and stable. Radiational cooling causes these air masses to form over Alaska and northern Canada. They travel south, east of the Rockies into the Plains, and finally east.

What causes air masses to move?

Large bodies of air with comparable humidity and temperature are called air masses. Predominant winds that blow in one direction circulate these air masses throughout the atmosphere. Weather fronts develop where two air masses meet. Rain, storms, and wind are all brought on by weather fronts.

In the high subpolar latitudes of the United States, a continental polar air mass is built up. This includes a large portion of northern Canada. A portion of the northern United States may aid in the development of this air mass if there is snow cover. The development of these colder air masses depends critically on snow cover.

What does the line indicated by the arrows most likely represent?

a front
an isotherm
high winds
high humidity

Answers

Final answer:

The line indicated by the arrows most likely represents a front, as it is associated with the counterclockwise flow around low pressure, precipitation, and changes in air and pressure typical of a front.

Explanation:

The line indicated by the arrows most likely represents a front. This is because the description mentions characteristics such as the counterclockwise flow around a center of low pressure in the Northern Hemisphere, changes in air direction ahead of and behind the front, and bands of rain along the warm and cold fronts. These features are indicative of a weather front, which is the boundary between two different air masses and associated with shifts in wind direction, temperature, humidity, and atmospheric pressure.

Weather maps often depict a front as a line with various symbols: red semi-circles for a warm front, blue triangles for a cold front, and purple with both symbols for an occluded front. Moreover, the presence of precipitation and changes in air pressure around fronts help meteorologists to predict weather patterns and upcoming weather conditions.
