If the space shuttle orbits the Earth at an altitude of 380 km, what is the
gravitational field strength due to
the Earth at that altitude? The
mass of the Earth is 5.98x 1024
kg, and the radius of the Earth is
approximately 6.37x106 m.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
