We get virtually all of our energy from the Sun. Therefore the answer must be either A or B. The Earth's surface receives little energy from the Sun (relative to how much is radiated) because most of it is absorbed and reflected by our atmosphere (clouds, ozone, etc.). Therefore I believe the ... It's heated by the sun.

Mostly by the sun, but without an atmosphere that heat would quickly radiate back to space. So the answer is that the sun provides the energy and the atmosphere helps to to trap that energy. Certain molecules in the atmosphere are better at...

Heat is transferred to the surface of the Earth from the hot Earth's core by conduction and from radiation from the Sun. The atmosphere is heated by absorption of some of the electromagnetic radiation from the Sun, and contact with the warm surface of the land and water. ... How is the Earth's surface heated?

When air near the Earth's surface is heated, it becomes less dense and rises. Cooler, denser air from above sinks. As the cool air sinks, it is heated by the ground and begins to rise. This process of warm air rising and cool air sinking forms convection currents.

Geothermal systems rely on the Earth's temperature for heating and cooling; in the winter, the system transfers heat from the ground into the building, and in the summer, the heat is transferred from the building back into the ground. Most of the campus buildings are heated by oil or propane. ACM already has...
