the highest layer of atmospher 500km+
very few molecules

hydrogen and helium
a high-speed high-altitude airstream blowing from west to east near the top of the troposphere
the shifting of winds currents from their expected paths that is caused by earth's rotation
a current that forms in the ocean because a mass of a seawater becomes more dense than the surrounding water and sinks
a current in the ocean that moves water horizontially,or parallel to earth's surface
currents created during the day because solar radiation warms the land more than the water,so the sea moves towards the warm land.
movement of air from land to sea at night, created when cooler, denser air from the land forces up warmer air over the sea and the sea moves away from the land
layer of electrically charged particles in the thermosphere that absorbs AM radio waves during the day and reflects them back at night
layer of the startosphere with a high concentration of ozone; absorbs most of the sun's harmful ultraviolet radiation
prevaling winds that blow from west to east between 30 degrees & 60degrees latitude in the hemisphere.
