Volcanic Landforms, Volcanoes and Plate Tectonics

Jan. 11, 2008 -- Four decades after the rise of the great, unifying theory of plate tectonics, geologists are still scratching their heads over a lot of the details.
ScienceDaily (Jan. 3, 2008) — Plate tectonics, the geologic process responsible for creating the Earth's continents, mountain ranges, and ocean basins, may be an on-again, off-again affair. Scientists have assumed that the shifting of crustal plates has been slow but continuous over most of the Earth's history, but a new study from researchers at the Carnegie Institution suggests that plate tectonics may have ground to a halt at least once in our planet's history--and may do so again. A key aspect of plate tectonic theory is that on geologic time scales ocean basins are transient features, opening and closing as plates shift.

Surface Ocean Currents
The water of the ocean surface moves in a regular pattern called surface ocean currents. the currents are named.
Ocean Currents and Climate
These deep waters sink into the deep ocean basins at high latitudes where the temperatures are cold enough to cause the density to increase. Solar heating cause water to expand. Near the equator the water is about 8 centimeters high than in middle latitudes.Thousands in D.C. protest pipeline - CBS News
