How do ocean currents affect costal region? |
|
Answer» CAUSES Just as the heating of air close to the ground causes convection that is the source of virtually all meteorological phenomena, the heating of equatorial waters is the cause of virtually all ocean currents. As water heats, it expands and this expansion causes it to push outward into cooler areas. As it cools, it contracts, and this contraction causes it to flow toward the area vacated by warm water. EFFECTS When land borders the ocean, the currents of the ocean warm or cool it, depending on the nature of the particular current that flows by that land. In cases where a warm current flows along a particular coast, that coastal area will generally be warmer than it would otherwise be if it were landlocked. Similarly, cool currents cause coastal lands to remain cooler than they would be if they were landlocked. |
