1) Convection currents<span> in the magma drive plate tectonics. Heat generated from the radioactive decay of elements deep in the interior of the </span>Earth<span> creates magma (molten rock) in the aesthenosphere. The aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the </span>Earth<span>that extends to 2900 km.
2) </span><span>The plates on the </span>Earth's<span> surface would be floating on top of the water. ...</span>Convection currents<span> in the liquid mantle </span>cause<span> the plates to </span>move<span>. At the top of the mantle, the rock encounters the thin </span>crust<span>, and, as it pushes it aside, lava flows out from the mantle to form new oceanic </span>crust<span>.</span>
Lines of latitude run from north to south and measure distances east and west of the prime meridian.
Latitude measures the distance north or south of the equator. Parallels, also called parallels, are imaginary lines that divide the earth. They run east-west but measure north or south distance. The equator is the best-known parallel. Latitude is measured by an imaginary line that divides the earth horizontally (the distance north or south of the equator).
The degree latitude, also called the meridian, is an imaginary line that divides the earth. They run north-south from pole to pole, but measure distances east or west. The prime meridian passing through Greenwich, England has 0 degrees longitude.
