Answer 1

Answer:

here is your answer

Explanation:

1. An atmosphere is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body. An atmosphere is more likely to be retained if the gravity it is subject to is high and the temperature of the atmosphere is low

2. Air is transparent to our eyes

Air is transparent to our eyes because we have evolved retinas that are sensitive to the very wavelengths of light that pass through it unobstructed – otherwise we wouldn't be able to see anything at all. Wind is just moving air, caused by pressure differences in the atmosphere.

3. Wind is the flow of gases on a large scale. On the surface of the Earth, wind consists of the bulk movement of air. ... In meteorology, winds are often referred to according to their strength, and the direction from which the wind is blowing.

4. a) Ice floats on water because it is about 9% less dense than liquid water. In other words, ice takes up about 9% more space than water, so a liter of ice weighs less than liter water. The heavier water displaces the lighter ice, so ice floats to the top....
