Heating the troposphere refers to the process by which the Earth's surface is warmed by the sun and then in turn heats the air above it. This heating creates temperature variations that drive weather patterns and atmospheric circulation within the troposphere, which is the layer of the Earth's atmosphere where weather occurs.
The main layers of Earth's atmosphere, starting from the surface outward, are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has distinct characteristics and plays a role in regulating the planet's climate and environment.
The Earth's surface is heated by the sun's radiation. The heated surface then warms the air in the troposphere through conduction and convection. This heating creates temperature gradients that drive atmospheric circulation patterns and weather systems within the troposphere.
Planetary wind belts in the troposphere are primarily caused by the uneven heating of Earth's surface by the sun. This differential heating leads to variations in air temperature and pressure, creating convection currents which result in the formation of the wind belts. The Earth's rotation also plays a role in shaping these wind patterns through the Coriolis effect.
The two main gases found in the troposphere are nitrogen (about 78%) and oxygen (about 21%). These gases make up the majority of the Earth's atmosphere and are essential for supporting life.
The major direct source of heat in the troposphere is the sun. Solar radiation warms the Earth's surface, which then heats the air above it through conduction, convection, and radiation. This process creates temperature variations that drive weather patterns and atmospheric circulation.

The major contribution in heating the troposphere comes from the sun's radiation. The sun warms the ground by radiation, which in turn warms the air heating the troposphere.

The sun heats the Earth, and then longwave radiation heats the troposphere via convection currents.

Infrared heat rises from the surface of the earth into the troposphere (the lowest level of the atmosphere). It is captured there by greenhouse gases, so the troposphere warms. This is called the greenhouse effect, and too much greenhouse gas means global warming.
