Describe the "Red Queen" theory of evolution.

Explanation:

The Red Queen hypothesis (also referred to as Red Queen's, the Red Queen effect, Red Queen's race, Red Queen dynamios) is an

evolutionary hypothesis which proposes that organisms must constantly adapt, evolve, and proliferate in order to survive while pitted against

ever-evolving opposing organisms in a constantly changing environment, as well as to gain reproductive advantage.

explanation:

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.
