Which best describes how energy from the sun helps to maintain life on Earth?

• It heats Earth’s atmosphere and surface, which helps stabilize temperatures on Earth and creates environments more favorable for life to exist.

• It forms the ocean’s water and the oxygen in the atmosphere that organisms need for life functions.

• It prevents the destruction of the magnetic field around Earth that protects all life forms

• It is absorbed by Earth’s mantle, which drives plate tectonics to form new land masses for organisms to live.
