Convection currents in the Earth's mantle are caused by:

• Less dense hot magma moving downward

• Less dense hot magma moving upward

• Tectonic plate movement

• More dense cooler magma moving upward

• Dense cold water rising

• Less dense water sinking

• Less dense warmer water rising and more dense cold water sinking

Wind is created when..

• Warm air moves in to replace cool air

• Dry air moves in to replace moist air

• Cool air moves in to replace warm air

• Both air masses are the same temperature
