Answer to Question 1

True

Answer to Question 2

Tides are produced by small differences in the gravitational force exerted on different parts of an object. The side of Earth nearest the Moon feels a larger force than the side farthest away. Relative to Earth's center, small forces are left over, and they cause the tides. Both the Moon and the Sun produce tides on Earth; sometimes they add together, and sometimes they partially cancel.
