which statement best describes why liquid water exists on earth? a. earth has moderate temperatures and a strong gravitational force. b. earth has hydrogen bonds with the sun. c. earth experiences comet crashes and volcanic eruptions. d. earth experiences a strong magnetic field and lunar tides.

Answer

Answer:

A. Earth has moderate temperatures and a strong gravitational force.

Brief Explanations:

Moderate temps keep water liquid, gravity retains atmosphere which helps maintain conditions for liquid - water existence. Hydrogen bonds don't form between Earth and Sun. Comet crashes and eruptions aren't main reasons for liquid - water presence. Magnetic field and tides don't directly cause liquid - water existence.
