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
a vertical circulation in the ocean that brings deep, cold water to the ocean 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
thin layer of air that forms a protective covering around the planet
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
one of the many types of energy that copmes from the sun
steady winds that blow 30 degrees latitude north and south
prevaling winds that blow from west to east between 30 degrees & 60degrees latitude in the hemisphere.
Prevailing winds that blow from east to west between 60degrees-90degrees latitude in both hemisphere.
