Why does it rain?Multiple choice question.Air warms as it rises, and water vapor condenses.Air cools, usually by rising, and water vapor condenses.Air cools as it rises, causing water to evaporate.
Solution
The correct answer is: Air cools, usually by rising, and water vapor condenses.
Here's why:
-
The process begins when the sun heats up the surface of the Earth, causing the temperature of the air at ground level to rise.
-
As the air warms, it becomes less dense and begins to rise.
-
As the air rises, it moves into areas of the atmosphere where the pressure is lower. This causes it to expand and cool.
-
When the air cools, its capacity to hold water vapor decreases. This is because cooler air is denser than warm air, and denser air can't hold as much water vapor.
-
When the air can't hold all the water vapor it contains, the excess water vapor condenses into tiny droplets of water, forming clouds.
-
When the droplets in the clouds combine and grow larger, they eventually become too heavy to stay in the air. This is when they fall to the ground as rain.
