Layers of the Atmosphere
This is the layer closest to the surface of the earth, where weather occurs.
These are the layers of the atmosphere (must name them in order from lowest to highest).
troposphere, stratosphere, mesosphere, thermosphere
The temperature decreases as altitude increases in these two layers.
the troposphere and mesosphere
Which form of heat transfer is responsible for the formation of winds?
convection
Earth and the moon heat up because they receive energy from the sun. This form of heat transfer through empty space is called ___.
radiation
This layer of the atmosphere contains the ozone layer.
the stratosphere
These are layers in which large jets can fly.
the troposphere and the stratosphere
This layer is the hottest layer of the atmosphere.
the thermosphere
What is the main source of energy that creates the motion in both the atmosphere and ocean?
the sun
When you step out of the shower, your feet transfer thermal energy to the floor as soon as you step on it. This form of heat transfer is called ___.
conduction
This layer has the least dense air of the atmosphere.
the thermosphere
This is the layer where space shuttles fly.
thermosphere (or exosphere)
In these two layers, the temperature increases as altitude increases.
the thermosphere and stratosphere
What is the main cause of local winds?
the uneven heating and cooling of land and water.
As you sit next to a campfire or a heater, the heat is transferred directly to you through ___.
radiation
The atmosphere contains 78% _______, 21%______ and 1% other gases. (In order)
nitrogen, oxygen
This layer of the atmosphere has the most dense air.
the troposphere
This layer is the coldest layer of the atmosphere, in which meteors burn up.
the mesosphere
What time of day do land breezes occur? Which area is warmer and which area is cooler?
1. During the night
2. Land is cooler, water is warmer
This form of heat transfer is the main reason for changes in the weather in the troposphere.
This is the part of the atmosphere in which the auroras (Northern Lights) occur.
the ionosphere (or thermosphere)
This is found in the stratosphere and is responsible for absorbing the sun's harmful rays.
the ozone layer
As altitude increases, air pressure gradually...
decreases
What time of day do sea breezes occur? Which area is warmer and which area is cooler?
1. During the day
2. Land is warmer, water is cooler
Convection currents form when –
areas receive unequal amounts of heat energy.
