Question

How are clouds formed and what factors affect their formation?

Answer 1

$\huge\red{Answer}$

Clouds form when air that is warm and moist cools and expands. Clouds are just tiny droplets of water in the atmosphere.

As Clouds are formed by way of four processes :

1) surface heating

2) mountains and terrains

3) air masses that are forced to rise and cool

4) cold or warm weather fronts.

1) The first process is perhaps the simplest: the sunheats the earth and thus the air, this warm air rises, expands, and cools, forming clouds like in the image above.

2) Clouds are also formed when air encounters mountains or other topography. The air rises and cools and, again, the air cannot hold all of the water it held when warm so clouds form.

3) The air is also forced to rise when wind in a low pressure system forces the air to rise up. Related to number 2, if air is forced to rise because of topography that slopes upwards, clouds may also form.

4) Finally, weather fronts cause cloud formation. Specifically, warm fronts create clouds because the warm air rises above the cold air and cold fronts create clouds because the cold air displaces or moves the warm air up.
