|
|
|
What is Convection? |
The transfer of thermal energy by the movement of particles within matter |
|
|
|
Where does conduction occur? |
Conduction occurs where the atmosphere contacts earth |
|
|
|
What do convection cells do? |
Convection cells, redistribute, thermal energy around the world |
|
|
|
Does warm air or cold air rise in the atmosphere? |
Warm air rises |
|
|
|
What kind of air puts more pressure on the earth? |
Cold air sinks and put more pressure on the earth |
|
|
|
Are polar easterlies, cold winds, or warm winds? |
Polar easterlies are cold winds they blow from east to west near the North Pole and the south pole |
|
|
|
Which direction do the prevailing westerlies flow? |
The prevailing westerlies flow from west to east. They are also steady winds. |

|
|
|
What type of wind carried Christopher Columbus to the New World in 1492? |

|
|
|
What is the phenomenon that causes moving air and water to appear to curve to the right in the northern hemisphere, and to the left in the southern hemisphere? |
Coriolis effect |
|
|
|
What happens when wind hits a mountain? |
It is deflected or forced upward |
|
|
|
Why are winds really strong over the ocean? |
There isn’t a landmass to break it up |
|
|
|
Name one thing that causes water to become more dense |
high salinity and cold temperatures cause water to become more dense |
|
|
|
True or false: dense water rises to the top |
False, dense water sinks |
|
|
|
What is a density current? |
density current is the vertical movement of water caused by differences in density |
|
|
|
What is a surface current? |
A surface current is a wind driven current that carries ocean water horizontally across the oceans surface |
|
|
|
True or false: as wind blows over ocean waterwater, it transfers, energy to the water |
True. As wind blows over the ocean, it transfers energy to the water. |
|
|
|
What causes the surface of the ocean water to move? |
Moving air particles that drag along the surface of the water cause the top portion of the ocean to move |
|
|
|
What is upwelling? |
Upwelling is the vertical movement of water toward the ocean surface. |
|
|
|
When does upwelling occur? |
Welling occurs when wind blows across the ocean surface and pushes water away from an area |
