Question 1

Which of the following events will occur as an ocean current moves from an equatorial region towards a polar region?

Accepted Answer

A)  The current will be warm as it leaves the equatorial region and begins to cool as it moves towards the polar region.This in turn will cause the air currents to become cooler as they move closer to the poles,creating a tundra type of biome.
B)  The current will be cool as it leaves the equatorial region and begins to warm as it moves towards the polar region.This in turn will cause the air currents to become cooler as they move closer to the poles,creating a tundra type of biome.
C)  The current will be warm as it leaves the equatorial region and begins to cool as it moves towards the polar region.This in turn will cause the air currents to become warmer as they move closer to the poles,creating a grassland type of biome.
D)  The current will be warm as it leaves the equatorial region and begins to cool as it moves towards the polar region.This in turn will cause the air currents to become warmer as they move closer to the poles,creating a desert type of biome.
E)  The current will be warm as it leaves the equatorial region and become even warmer as it moves towards the polar region.This in turn will cause the air currents to become warmer and drier as they move closer to the poles,creating a tundra type of biome.F) A) and C)
G) A) and B)
