In which layer of the earth's atmosphere are clouds and weather formed?

A.
troposphere
B.
thermosphere
C.
stratosphere
D.
mesosphere

Troposphere

Explanation:

The air is heated from the ground up because the surface of the Earth absorbs energy and heats up faster than the air. The heat is mixed through the troposphere because on average the atmosphere in this layer is slightly unstable. Weather occurs in the Earth's troposphere. In fact, most clouds form in this layer.

Troposphere.

Explanation:

Troposphere is the lowest layer of the atmosphere. Clouds and weather are formed in this layer.

Tropopause , a layer of air bond to the top of troposphere and it separate it from stratosphere. Air is densest at the Troposphere.

It provide oxygen to the Earth which we breathe in.

The air contain 78% nitrogen, 21% oxygen and 1% is made of water vapour, argon and carbondioxide.
