- 2. Multiple Choice
In what direction will air currents most likely move
From the land towards the sea
straight down over land
straight up above the sea
from the sea toward the land

The wind will blow towards area A
The wind will blow towards area B
The wind will stop blowing
The wind will blow from both area A and B

A
B
C
D
- 5. Multiple Choice
Upward and downward currents of air which result fro the uneven heating of the air are called
Convection currents
Radiation currents
Winds
Conduction currents
- 6. Multiple Choice
Land breezes occur during the_____ and produce wind moving _______
night/in over the land
day/out over the water
day/in over the land
night/out over the water
- 7. Multiple Choice
What is the driving force for surface ocean currents?
global winds
density layering
moons gravity
salt concentration
- 8. Multiple Choice
Why does warm air rise and cold air sink?
because warm air is denser than cold air
because warn air is less dense than cold air
because cold air is less dense than warm air
because warm has less pressure than cold air does
- 9. Multiple Choice
What are the major controlling factors for deep ocean currents?
salinity and temperature
wind and pressure
continental deflection
- 10. Multiple Choice
Which two statements that explains why cold water currents are most likely be located deeper than warm water currents?
winds push cold water down
cold water is less dense due to higher salinity
ocean tides force cold water downward
cold water is more dense due to higher salinity
cold water is more dense and sink
- 11. Multiple Choice
Why does the rain shadow exist on the leeward side of the mountain ranges?
the air descends on the leeward side of the mountain is warm and dry
It is too far from the ocean to hold moisture long enough to drop it in the area of a rain shadow
Soils are too thin in these regions to hold moisture, so none is available for evaporation
These areas are generally very cold and all water is frozen and not available for evaporation
- 12. Multiple Choice
Which of these is an example of convection?
cool air rising and warm air sinking?
warm air rising and cool air sinking
the sun heating the Earth
burning your feet on hot pavement
- 13. Multiple Choice
What is the factor that drives the currents to continue to circulate?
continental deflection
the rotation of the Earth
the gravity of the moon
difference in density of ocean water
- 14. Multiple Choice
When the air above the water gets cold, what happens to the water molecules?
The molecules slow down and move closer together, increasing the water's density
the water's volume increases as molecules move closer together
the denser water floats on top of the chilled water
the water molecules evaporate, decreasing the water's density
- 15. Multiple Choice
Compared with surface currents, deep currents are
warmer and denser
colder and more dense
colder and less dense
warmer and less dense
- 16. Multiple Choice
What energy source formed this convection current in the atmosphere?
gravity from the moon
heat from sun
rotation of the Earth
action of tides
- 17. Multiple Choice
Which of these currents most affects the east coast of the United States?
Gulf Stream
Labrador Current
North Atlantic Drift
North Equatorial Current
- 18. Multiple Choice
Why are ocean currents important to coastal regions?
they produce both high and low tides along coastal regions
they can warm or cool the air temperature along coastal regions
They move vertically pushing warm water and nutrients to the surface along coastal regions
They increase the rate of precipitation as cold water moves along coastal regions
- 19. Multiple Choice
Which of the following best describes how the Gulf Stream affects the weather along the east coast (of the US) ?
it makes the air less humid and brings less rain to the area
it makes the temperature cooler and wind stronger
it makes the wind strong and brings less rain to the area
it makes the air temperature warmer and the air more humid
