Atmospheric movements We learned that energy is transferred from the Sun to the Earth creating convection currents. But, what type of currents???
Convection Regions, Global Winds, Jet Streams. Atmospheric Convection Regions Since earth is unevenly heated, climate zones occur (different convection.
Solar Energy & The Greenhouse Effect The driving energy source for heating of Earth and circulation in Earth’s atmosphere is solar energy (AKA the Sun).
