They are measured in degrees.
Since Earth is roughly a sphere, and there are 360 Degrees in a circle, you can expect that there will also be 360 degrees. And in fact, there are 180 degrees East and 180 Degrees West - which together makes it 360 Degrees.
Answer:
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.

<span>The correct answer is plate tectonics. The outermost shell of Earth, called the lithosphere, is partitioned into different tectonic plates (7 or 8 major ones). When a plate breaks along what are called faults, there is a release of energy, which causes seismic waves (the ground shaking). This shaking then causes several plates to rub against each other, and when they break, the earthquake results.</span>
