| #3 | Hot air balloon | CONVECTION |
| #4 | Ice cooling down your hand | CONDUCTION |
| #5 | Heat from a fire | RADIATION |
| LAYERS OF THE ATMOSPHERE | ||
| #1 | Layer of the atmosphere that we live in. | TROPOSPHERE |
| #2 | Layer of the atmosphere that absorbs ultraviolet radiation. | STRATOSPHERE |
| #3 | Layer of the atmosphere that is most dense. | TROPOSPHERE |
| #4 | Temperature rises in this layer due to ozone. | STRATOSPHERE |
| #5 | Most meteors that enter the atmosphere burn up within this layer. | MESOSPHERE |
| TRUE OR FALSE | ||
| #1 | Air density increases with altitude. | FALSE |
| #2 | About 50% of solar energy is absorbed by Earth's surface. | TRUE |
| #3 | Most visible light that enters Earth's atmosphere is reflected back out into space by greenhouse gases | FALSE |
| #4 | The troposphere, the layer of atmosphere closest to the ground, is heated by Earth's surface through the process of conduction. | TRUE |
| #5 | If there was less ozone in the atmosphere, more UV radiation would reach Earth's surface because fewer ozone molecules would be present to absorb the solar UV radiation. | TRUE |
| MISCELLANEOUS | ||
| #1 | Two most common elements that make up Earth's atmosphere. | NITROGEN AND OXYGEN |
| #2 | 56dm = ______ m | 5.6 m |
| #3 | In which cycle does rain return liquid water to Earth's surface? | WATER CYCLE |
| #4 | Volcanoes and the burning of fossil fuels which add gases and particles to the air are two sources of this. | AIR POLLUTION |
| #5 | List the following pollutants as either gases (g) or particles (p): dust, ozone, pollen, carbon monoxide, methane | PARTICLES: pollen, dust GASES: ozone, carbon monoxide, methane |
| Final Question | |
| When weather conditions and sunlight are likely to produce smog, cities may ask motorists to refuel their cars at night instead of early in the day. Why would this behavior make a difference? | SMOG FORMS WHEN CHEMICALS REACT WITH SUNLIGHT. AT NIGHT, THE SUN IS NOT SHINING SO LESS SMOG WOULD FORM. |
