radiation & gravity
Only partially, by warm winds. Mainly radiation from our Sun gives us heat.
Earthquakes occur all over earths surface because isolated regions are ice and for example California is not ice it is heat
Rock is a very poor conductor of heat and there is quite a lot of it between the surface and the mantle. As a result heat conducts to the surface very slowly and quickly radiates into space. As a result the vast majority of heat at Earth's surface comes from the sun. The heat from the mantle is felt at erupting volcanoes where magma, which ultimately gets it heat from the mantle, reaches the surface.
well hot goes up and cold goes down
troposphere
The sun heats the atmosphere. Solar radiation largely passes through the atmosphere and warms the surface of the earth. The earth then radiates heat up into the lower levels of the atmosphere where greenhouse gases warm. The warmed greenhouse gases then continue to radiate heat in all directions warming the atmosphere and again the earth's surface.
Energy is transferred between the earths surface and the atmosphere via conduction, convection, and radiation. Conduction is the process by which heat energy is transmitted through contact with neighboring molecules.
pressure from the heat under the earths surface
Earth's surface is free to radiate heat into space. The interior is not. The interior does transfer heat the the surface, but rather slowly. It is hot due to residual heat from Earth's formation and from the heat generated by the decay of radioactive elements.
Beneath the surface of the earth temperature remains the same. Within the Earth, irregular convection cells within the mantle transfer heat from the core to the surface of the planet. Volcanoes and earthquakes are two examples of heat transferring from the interior to the surface.

the answer is radiation
Convection, radiation, and conduction
Because of the heat and light
