Atmosphere and Heat
Layers of Atmosphere, Heat Transfer, Factors of Weather
| Question | Answer |
|---|---|
| What gas appears the most in our atmosphere? | nitrogen |
| List the layers of the atmosphere in order starting with the Earth. | troposphere, stratosphere, mesosphere, thermosphere, exosphere |
| layer of the atmosphere where weather happens | troposphere |
| layer of the atmosphere where most meteors burn up | mesosphere |
| Explain the Greenhouse Effect. | During the day, the sun shines through the atmosphere and heats the Earth's surface. At night, the surface cools and releases the heat back into the air. Some of the heat is trapped by the greenhouse gases in the atmosphere. |
| What do we call meteors that burn up? | shooting stars |
| hottest layer of the atmosphere | thermosphere (Think: "Therm-" means heat.) |
| outermost layer of the atmosphere | exosphere (Think: "Exo-" means outside.) |
| layer of the atmosphere that contains the ozone layer | stratosphere |
| conduction | Energy is transferred by direct contact. |
| convection | movement in liquids or air where hot, less dense materials rise and cooler, more dense materials sink |
| radiation | Energy is transferred by electromagnetic radiation. |
| weather | atmosphere over short periods of time |
| climate | average weather of an area over a long period of time |
| type of air that moves faster | warm |
| type of density and pressure caused by warm air | lower density and lower pressure |
| What is wind? | air moving in a specific direction |
| What does wind do? | helps spread the Earth's heat by making the temperature in an area cooler or warmer |
| What is humidity? | the amount of water vapor present in the air |
| type of air created by low humidity | dry |
| More water vapor is found in what type of air? | warm |
| How does a cloud form? | Warm air rises, expands, cools, and condenses. |
| What makes up air pressure? | temperature, wind, and humidity |
| What causes weather? | water, sun, air |
| How can clouds affect weather? | blocking the sun's heat (radiation), trapping heat, reflecting heat |
| What determines whether rain, sleet, snow, or hail forms? | air temperature |
| Why is it important to protect the stratosphere? | It contains the ozone. The ozone protects from the sun's radiation. |
