The sun
The air in the troposphere is warmed by heat from the Earth's surface through the process of conduction and convection. As the Earth's surface absorbs solar radiation, it heats up and transfers some of this heat to the air directly above it. This warming of the air creates temperature gradients and drives weather patterns and atmospheric circulation.
Air warmed by heat from the Earth's surface is known as "thermal air" or "warm air." When the Sun heats the Earth's surface, it in turn warms the adjacent air, causing it to rise due to its lower density. This process is crucial for weather patterns and atmospheric circulation, as the rising warm air can lead to cloud formation and precipitation. Additionally, this warmed air plays a significant role in regulating the Earth's climate.
The sun can only shine on part of the earth's surface at any one time. This is why we have day and night in a rolling approach as the earth rotates.

There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
