Atmosphere Vocabulary Practice
Science/Key/Block # ________ Date: _________
Directions: Use vocabulary words to fill in the blanks.
*Not all the words will be used!!
1. The layer of air that surrounds the Earth (like a blanket). The atmosphere is made up of a mixture of gaseous
elements and compounds and a small amount of tiny solids and liquids. The atmosphere is held close to Earth
due to gravity. ______________________
2. A layer of a special kind of oxygen (ozone = O3) found in the stratosphere that protects life on Earth from the
sun’s harmful ultraviolet rays.________________________
3. “Rivers” of high-speed air in the atmosphere, found in the stratosphere. It affects air masses and affects aircraft
by speeding or slowing their path._____________________
4. The movement of air from a region of high pressure to low pressure. ____________________
5. The outermost atmospheric layer that merges with space and contains very few
molecules.________________________
6. The middle layer of Earth’s atmosphere where most meteoroids burn up.
The temperature decreases as altitude increases.___________
7. The height above a specific point, as the surface of Earth or sea level._________________________
8. The atmospheric layer between the mesosphere and the exosphere where the molecules contain the most heat
energy; the Northern and Southern lights, known as the auroras are found here. The ionosphere. The
temperature increases as altitude increases.____________
9. The second layer from the Earth’s surface. It contains the ozone layer. The temperature increases as altitude
increases due to the ozone layer’s absorption of ultraviolet rays from the sun._________________
10. The average amount of energy from the motion of the molecules of a substance._______________________
11. When warm air enters a region the molecules move further apart and rise usually bringing clouds and
precipitation. ________________________________
12. The transfer of heat energy by the movement of molecules from one place to another through a liquid or gas.
Hot air or liquids rise because they become less dense while cold air/liquids sink due because they become
denser. The fluids move in a circular pattern, or convection current as a result.___________________________
13. The lowest layer of the atmospheric, containing about 75% of all the air in the atmosphere. It contains the air
we breathe and is where weather, clouds, and air pollution are found.________
The temperature decreases as altitude increases.___________
14. The upper parts of the atmosphere where ions (charged atoms) are found. Radio waves bounce off the
ionosphere.__________
15. A form of energy given off by light with wavelengths that is shorter than visible light. Ultraviolet rays are harmful
to living things._________________
16. The transfer of energy (including heat) through electromagnetic (light) waves. Examples include: radio,
microwave, infrared, ultraviolet, visible light, x-rays, gamma rays ________________________
17. When heat is transferred between solid substances by direct contact. _______________________
