Which part of the diagram supports her claim?



A.
Diagram of a larger Earth

B.
Diagram of a smaller Moon

C.
Longer lines of gravitational force moving towards Earth

D.
Shorter lines of gravitational force moving towards the Moon

Answer 1

C. Longer lines of gravitational force moving towards Earth.

Those longer/denser field lines indicate a stronger gravitational field from Earth than from the Moon, so the Moon is pulled more toward Earth and is kept in orbit.
