Which event typically causes upwelling? wind blows warm water away from the shore. warm water rises to the surface of the ocean. neap tides move cold water away from the shore. cold water falls to the bottom of the ocean and pushes warm water up.

The correct answer is option A, Wind blows warm water away from the shore

Reason:

During Upwelling, warm wind blows along a coastline and thus causes water at the ocean surface to move away from it through a process called Ekman transport. When surface water moves away from the coast, water from deeper in the ocean rises up and takes its place.

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.
