Name : ___________________________ Period _____ Name : ___________________________ Period _____ How does energy form the sun heat the Earth? How does energy form the sun heat the Earth? Earth gets most of its energy from the Sun. This energy heats up the atmosphere and drives the processes that form both weather and climate. Weather is the states of the atmosphere at a given time and place. Climate refers to an area’s long-term weather patterns. Earth and its atmosphere are heated by radiation, conduction and convection. Radiation is the transfer of energy by waves, such as electromagnetic waves from the Sun. Conduction is the transfer of energy between objects that are touching. Convection is the transfer of energy by the movement of a liquid or gas, such as air. Radiation from the sun heats Earth’s surface. Conduction causes heat energy from the Earth’s surface to transfer to the atmosphere. Warm air is less dense that cooler air, so it rises, warming that air above the surface by convection. As the air rises, it cools, becomes more dense, and sinks back to the Earth’s surface. There it is warmed again. This warming and cooling cycle is creates air currents that constantly move through the atmosphere. Earth gets most of its energy from the Sun.
