Which of the following is NOT something that Earth's atmosphere protects us from? A. meteoroids B. ultraviolet light C. greenhouse gases D. dangerous particles from space

Answers

Answer:

The correc answer is C. greenhouse gases.

Explanation:

The atmosphere is a layer of gases that surrounds our planet and is one of the essential elements for life on it.

The atmosphere protects us from harmful solar radiation from the Sun. The Sun, in addition to light and heat (infrared radiation), emits other radiation such as gamma rays, X-rays and ultraviolet rays that are harmful to life. These harmful radiations are absorbed by the atmosphere.

The atmosphere also protects us from the impacts of meteorites. These are from outer space are attracted by gravity and fall on the earth's surface. Upon coming into contact with the gases of the atmosphere, at high speed, the friction causes them to heat up so much that they become incandescent and end up disintegrating, avoiding reaching the ground. Only the largest (rare) can pass through the atmosphere and reach the ground.

Something similar happens that with meteorites occurs with the dangerous particles of space.

Greenhouse gases contribute, to a greater or lesser extent, to the increase of the greenhouse effect, since they are capable of absorbing the heat energy carried by long-wave radiations that are reflected by the Earth's surface.This phenomenon prevents the solar energy constantly received by the Earth from returning immediately to space and causing the temperature of the air near the ground to rise. Then there are changes in the climate such as sea level rise, changes in rainfall, disappearance of forests, extinction of organisms and problems for agriculture.

So the correc answer is C. greenhouse gases.

the answer in C. Greenhouse Gases. Greenhouse Gases is caused by the trapped heart in the atmosphere harming us which we will always have. hope this helped

If the water is hot then the food coloring will spread faster,because?

Answers

Answer:

Warm water has more energy than cold water. The more energy the more the water molecules move around pushing the food coloring. Think gas—liquid is evaporated because of heat and the molecules move more than in a liquid state.

Suppose the plates beneath Earth's surface stopped moving.What do you think would happen?Explain your answer.

Answers

There would be no more earthquakes or volcanic eruptions as the earth's plate are the cause of both these occurrences.(which can be seen as a positive)
However, the plates allow the earth to cool when they move because they cause heat loss.If the plates were to stop moving the earth would have to loose heat another way and since we cant tell how this would happen, it could be very dangerous.
