Earth’s Systems and Cycles For Chapter 3 Test Study Guide

Define heat flow The transfer of energy from warmer objects to cooler objects

How does heat from earth’s interior reach the surface? By convection

Explain the convection current It’s uneven heating and density differences in the oceans

Where does earth get its energy From the sun

Define temperature It is a measure of the average kinetic energy of an object’s particles

Define radiation The transfer of energy as electromagnetic waves, how energy is transmitted from the sun to Earth.

Define conduction The process by which heat flows from the warmer geosphere to the cooler atmosphere.

Define convection The transfer of energy due to the movement of matter; how most energy moves through the atmosphere and hydrosphere
