The ozone layer is located in the_______. |
Stratosphere |
|
Convection is defined as the______. |
Transfer of heat by currents |
|
What is not a greenhouse gas? |
Nitrogen |
|
Liquid water turns into gaseous water vapor in a process called_______. |
Evaporation |
|
Currents at the surface of the ocean are moved mostly by______? |
Wind |
|
Which of the following statements about the biosphere is not true? |
Matter is constantly added to the biosphere |
|
Why does land that is near the ocean change temperature less rapidly than land that is located farther inland? |
The ocean absorbs over half of the solar radiation, it absorbs and releases heat more slowly than land. The temperature in the atmosphere changes slower too, than further inland does. |
|
__% if the air we breathe is made up of nitrogen. |
78% |
|
__% of the air we breathe is made up of oxygen. |

Troposphere, Stratosphere, Mesosphere, Thermosphere |
|
_____ moves the energy through space in waves from the sun to heat the Earth's surface. |
Radiation |
|
_____ is the flow of heat from a warmer object to a colder one. |
Conduction |
|
_____ is the transfer of heat by air currents. |
Convection |
|
How does solar energy reach the Earth? |
Solar energy reaches the Earth as electromagnetic radiation, which includes visible light, infrared radiation, and ultraviolet light. |
|
Explain what causes Earth's weather. |
The troposphere is the layer of the atmosphere where weather occurs. It's Earth's densest atmosphere, the temperature decreases as altitudes increase in the troposphere. |
