Unit 4 - Role of Oceans and Weather

Earth's land areas, oceans, and atmosphere maintain fairly constant average temperatures. What is the best explanation for these constant average temperatures?

• Earthś Northern Hemisphere and Southern Hemisphere have opposite seasons

• Earth is tilted and rotates daily on its axis

• The continuous motion of air and water distributes the sun's energy

• Global weather systems generally move from west to east
