Nutrients are brought to the surface for phytoplankton to use at ________.

• upwellings

• downwellings

• eddies

• gyres

The layer in a large body of water in which temperature drops with increasing depth faster than it does in other layers is called the __________.

• thermocline

• pycnocline

• downwelling

• upwelling

What role do gyres, like the Gulf Stream, play in Earth's climate?

• transporting nutrients from poles to the equator

• transporting heat from high latitudes to low latitudes

• transporting warm Pacific Ocean water to Florida

• transporting heat from equator to poles

Why would you expect to find denser water at high latitudes?

• sea ice formation

• evaporation

• rapid glacial melting

• cold water can dissolve more salt and oxygen
