How can you find directions using satellite orbiting?

Satellites may move north to south, or south to north, or west to east, but never from east to west. When satellites are launched, they always head eastward to take advantage of the Earth's rotation, going more than 1,000 miles per hour near the equator. This saves a lot of fuel.

Igneous rocks are formed from solidification and cooling of magma. The magma can be obtanied from partial melts of pre-existing rocks in either the planet's mantle or crust. Plutonic or intrusive rocks area result of when the magma cools and crystallizes slowly within the Earth's crust. A example is granite.
