Atmosphere and Heat

Layers of Atmosphere, Heat Transfer, Factors of Weather

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.
