The pie chart below shows the major components of the earth's atmosphere. based on the chart, earths atmosphere can be descibed as

a mixture of gases

Explanation:

The Earth's atmosphere consists of nitrogen, oxygen, and trace amounts of other gases, such as argon, water vapor, and carbon dioxide.

Therefore, the Earth's atmosphere can best be described as a mixture of gases.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
