Section 2 Energy Transfer in the Atmosphere

Section Goals I will describe what happens to the energy Earth receives from the sun. I will compare and contrast conduction, convection, and radiation. I will explain the water cycle.

Vocab Words (Chapter 1 due Friday) Radiation Conduction Convection Hydrosphere Condensation

Some energy from the Sun is reflected back into space some is absorbed by the atmosphere, and some is absorbed by land and water on Earth's surface

Heat—energy that flows from an object with a higher temperature to one with a lower temperature Radiation—energy transferred in rays or waves (Sun) Conduction—transfer of energy when molecules bump into each other through contact (Touching a hot plate) Convection—transfer of heat by the flow of a material (lava lamp)

The water cycle—water moves back and forth between Earth's atmosphere and surface http://www.crickweb.co.uk/assets/resources/flash.php?&file=watercycle

Energy from the Sun causes water to evaporate from the hydrosphere, and rise as vapor.

Water vapor in the atmosphere can cool and return to liquid form through condensation. a. When water vapor condenses, clouds of tiny water droplets may form. b. Water droplets collide to form larger precipitation

Condensation
