Energy from the Sun The sun provides most of Earth’s energy This energy causes winds and ocean currents and allows plants to grow and produce food providing nutrition for animals The sun provides most of Earth’s energy This energy causes winds and ocean currents and allows plants to grow and produce food providing nutrition for animals

Energy from the Sun When Earth receives the sun’s energy 3 things can happen: It’s reflected back into space by clouds, particles, and Earth’s surface It’s absorbed by the atmosphere It’s absorbed by land or water When Earth receives the sun’s energy 3 things can happen: It’s reflected back into space by clouds, particles, and Earth’s surface It’s absorbed by the atmosphere It’s absorbed by land or water

Heat Energy that flows from an object with a higher temperature to an object with a lower temperature Heat from the sun heats the Earth’s surface Energy that flows from an object with a higher temperature to an object with a lower temperature Heat from the sun heats the Earth’s surface

Heat Transfer Heat is transferred through the atmosphere to Earth in 3 ways: Radiation Conduction Convection Heat is transferred through the atmosphere to Earth in 3 ways: Radiation Conduction Convection

Radiation Energy that is transferred in rays or waves Example: The sun warms your face Energy that is transferred in rays or waves Example: The sun warms your face

Conduction Energy that is transferred by direct contact Example: Touching a hot stove Energy that is transferred by direct contact Example: Touching a hot stove

Convection The transfer of heat in a fluid or gas that Happens when the substance warms, expands, and rises Example: Warming Soup The transfer of heat in a fluid or gas that Happens when the substance warms, expands, and rises Example: Warming Soup
