Mo9-L4: Vocabulary Review

Direction: On each line, write the term that correctly replaces the underlined words in each sentence

conduction convection process radiation
ref ect stability temperature inversion

1. In the area of the atmosphere that is closest to Earth’s surface, the transfer of
thermal energy by collisions between particles of matter occurs.

2. About one-quarter of the Sun’s radiation does not reach Earth because clouds and
small particles in the air bounce back solar waves.

3. Visible light, ultraviolet light, and infrared radiation waves are types of
electromagnetic waves that transfer thermal energy from the Sun.

4. Close to Earth’s surface, where conduction occurs, the transfer of thermal energy
by the movement of matter from one place to another can also occur.

5. The formation of thunderstorms depends on the strength or weakness of
circulating air motions of the atmosphere.

6. A layer of cooler air near Earth’s surface is trapped by a layer of warmer air when a
condition in the troposphere that involves a temperature increase with altitude
occurs.

7. The Sun’s energy reaches Earth through an ordered series of actions known as
radiation.
