Currents in the ocean are caused by differences in water density. colder, denser water tends to
a.
rise and flow from west to east.
b.
sink and flow from the equator to polar regions.
c.
rise and flow from east to west.
d.
sink and flow from polar regions to the equator.

The answer is D.

Explanation:

Just like how cold air falls and warm air rises the same is with water.

Also the places with the coldest water is the north and south pole. The equator is relatively always warm so yeah.

b.

explanation:

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

mass:
