Question 1.1.(TCO 9) Every day tremendous amounts of the sun’s energy strikes the earth. Why doesn’t the earth overheat? (Points : 3)
Much of the heat melts rocks forming lava deep inside the earth.
Most of the energy is used in photosynthesis to help plants grow and survive.
The energy mostly is absorbed in various weather systems.
The energy is ultimately radiated back to space.
