Because of the pressure in the center of the earth. Which also cause earthquakes.
Edit:
No. Most of the heat comes from the sun and is reflected back out.
The atmosphere is heated from below because the Earth's surface absorbs solar radiation, which warms the ground. The warm ground then heats the air in contact with it through conduction and convection, causing the lower atmosphere to be warmer than the upper atmosphere. This temperature difference sets up vertical air movements that drive weather systems and the circulation of the atmosphere.
Mercury and the Moon do not have significant atmospheres. Mercury's thin exosphere mainly consists of atoms blasted off its surface by the solar wind, while the Moon has virtually no atmosphere, making them both airless bodies in our solar system.
the US is not in the southern atmosphere. it is in the northern atmosphere. northern is on the north of the equator.
Precipitation that is stored below the ground is referred to as groundwater. It fills the spaces between rocks and soil particles in the subsurface and can be accessed through wells for drinking water or irrigation purposes. Groundwater is an important natural resource that plays a vital role in supporting ecosystems and human activities.
The Earth's atmosphere traps heat through a process called the greenhouse effect. Greenhouse gases in the atmosphere, such as carbon dioxide and water vapor, allow sunlight to pass through and warm the Earth's surface. When this heat radiates back towards space, the greenhouse gases trap some of it, preventing it from escaping and leading to an overall warming of the planet.
Reykjavik, the capital of Iceland, is heated by volcanic springs. The city's geothermal energy infrastructure harnesses the heat from underground geothermal sources to provide heating for homes and businesses in the area.
The atmosphere is more heated from below because the air is thicker the farther down you go, and so it traps the heat in the air.
by the radiation that is reflected back ar re-radiated by the land or water bodies
The lower atmosphere is heated by the ground, which is heated by sunlight.

air gets heated with carben dioxid and the rays of the sun
Earth is heated by the sun, which is a star.
Because sunlight is absorbed mostly by solid objects (not the gasses of the atmosphere), so the ground heats up, and warms the air adjacent to it.
When Earths surface is heated it radiates some of the energy back into the atmosphere as "Infrared Radiation."
