24
Q

horizontal lines (measuring north to south)

A

latitude

25
Q

vertical lines (measuring east to west)

A

longitude

26
Q

how is the earth’s surface warmed by the sun

A

unevenly

27
Q

helps drive the ocean and atmospheric circulation

A

heat

28
Q

does the ocean or atmosphere absorb more heat

A

ocean

29
Q

drive currents at the ocean’s surface

A

wind

30
Q

deeper currents are driven by differences in

A

density

31
Q

mixing and upwelling in the ocean transport nutrient rich waters to the ocean’s

A

surface

32
Q

extreme variation in sea surface ______ and ______ affect the ocean and atmosphere circulation

A

heat and temperature

33
Q

replacement of _____ and ______ water leads to air temperture swings and changes in humidity

A

cold…hot

34
Q

when heat is exchanged from the ocean’s surface to the atmosphere, it influences the

A

climate

35
Q

what 3 factors help form currents

A

climate, corolis effect, and landforms

36
Q

cirular patterns of cuurents are called

A

gyres

37
Q

names of the 5 gyres

A
Indian Ocean Gyre (generally flowing counter-clockwise)
North Atlantic Gyre.
North Pacific Gyre.
South Atlantic Gyre.
South Pacific Gyre.
38
Q

where do many gyres originate

A

the equator

39
Q

where is water equal in temperture

A

the equator

40
Q

surface currents transport warm water from the equator to the

A

poles

41
Q

factors that play a role in deep and surface currents are

A

winds, tempertures, density, corolis effect, coastal land, sea floor features, and salinity

42
Q

why is warm air less dense

A

The molecules are packed closer together. The amount of water vapor in the air also affects the density of the air.
