6th Grade Chapter 16 Answer Key
1. An invisible form of energy with wavelengths that are a little bit shorter than visible light.
2. Infrared radiation is the form that most of the energy that heats Earth’s atmosphere.
3. The greenhouse effect is the process by which gases hold heat in the atmosphere.
4. Thermal energy is the total energy of motion in the particles of a substance.
5. Zero degrees Celsius
6. Conduction is heat transfer between two substances that in contact
7. Radiation
8. Convection is the transfer of heat by the movement of a fluid—Remember: cold air is more dense than warm air
9. Differences in air pressure
10. Anemometer
11. Local winds are caused by unequal heating within a small area; global winds are in large areas
12. Land breezes occur because land cools of faster than water
13. The way Earth’s rotation makes winds curve.
14. Weak winds
15. At about 30 degrees north and south latitudes
16. When water vapor in the air becomes liquid water or ice crystals
17. The cooling of the air and the presence of particles in the air
18. Large clouds that often produce thunderstorms
19. Very high feathery clouds
20. Layered clouds that often cover much of the sky and are a dull gray color
21. Any form of water that falls from clouds
22. The temperature of the ice pellets and the size of the ice pellets
23. Electromagnetic waves are the form of energy that travels through space to Earth.
24. Visible light, infrared radiation, and ultraviolet radiation.
25. The process in which gases in the air hold much of the energy that is radiated from Earth’s surface
26. To measure air temperature
27. The increased cooling that wind can cause
28. Uneven heating of the atmosphere leads to differences in air pressure, which causes wind.
29. The process in which water vapor becomes liquid water
30. Clouds that form near the ground and look like fluffy heaps of cotton
31. Flat, layered clouds that cover most of the sky
