In one word... radiation. More specifically... the sun heats the Earth's surface, and the absorbed heat radiates back into the atmosphere.
weak and strong,it depends
The process known as convection moves energy from Earth's surface to high in the troposphere. As the Earth's surface is heated by the sun, warm air rises due to its lower density, creating vertical air movements. This transfer of heat through convection helps redistribute heat throughout the atmosphere.
Cool Air! As the heated air rises the heated air starts getting cool. This is because the higher the air is the colder it gets. Then the heated air will be replaced with cold air. As the cold air then comes down near the ground the cool air will become heated because of the sun. Heated Air - Cool Air - Cold Air And On And On It Goes
Away from the poles because the air near Earths surface is warm.
The dense air sinking towards the Earth's surface is called subsidence. Subsidence can lead to high pressure systems and stable weather conditions.
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.
It's heated through the convection currents.
the air being heated by the sun
As air near Earth's surface is heated by the sun, it becomes less dense and lighter than the surrounding air. This lighter, warmer air rises due to convection, creating vertical air currents. As the air rises, it cools and may condense to form clouds and precipitation, playing a key role in the Earth's weather systems.
Frontal wedging
Convection within Earth's atmosphere is primarily driven by the unequal heating of the Earth's surface by the sun. As air near the surface is heated, it becomes less dense and rises, creating an upward flow. As the heated air rises, it cools, becomes denser, and eventually sinks back towards the surface, completing the convection cycle that helps drive weather patterns.
convection
air pressure is the highest near the earths surface
The atmosphere near Earth's surface is heated from below primarily through the process of conduction. This occurs as the Earth's surface absorbs solar radiation and heats up, transferring this heat to the adjacent air molecules through direct contact. As the air warms, it becomes less dense and rises, creating convective currents that distribute the heat throughout the atmosphere.
Air is heated by conduction when it comes into direct contact with a warmer surface, such as the ground or a heated object. The heat energy is transferred from the surface to the air molecules through direct contact, causing the air molecules to gain kinetic energy and move faster, increasing the air temperature.

A meteor. Technically, a "meteor" is the flash of light itself. Once the rock hits the Earth's surface (IF it survives) it is called a "meteorite".
