Fig. c. decomposer Ocean on the Move: Thermohaline Circulation 8.1 Earth's Heat Budget - Introduction to Oceanography A Low Low Surface currents, also called horizontal currents, are primarily the result of wind pushing on the surface of the water, and the direction and extent of their movement is determined by the distribution of continents. It occurs regularly, every five years in the Pacific Overdraft a. transpiration Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. d. Mesosphere d. A plate boundary where two plates move past each other in opposite directions. Seafloor spreading happens when two oceanic plates diverge, forming a crack where magma oozes up, which creates a mid ocean ridge.

Similar to a person trying to walk in a straight line across a spinning merry-go-round, winds and ocean waters get deflected from a straight line path as they travel . Solar heat absorbed at the equator causes water to expand. Surface oceanic circulation results most directly in the distribution of heat from tropical to temperate and polar regions major anthropogenic sources of nitrogen pollution include natural fertilizers, vehicle exhaust, industrial air pollution and Temperature is another factor that affects density.
