The Moon: Tides & Eclipses

Front

What is the primary reason the Moon has a greater influence on Earth's tides than the Sun?

Back

The Moon is closer to Earth than the Sun, resulting in a stronger gravitational pull.

Front

How does increasing the distance from the Earth to the Moon affect the tides?

Back

The difference between high and low tide would be much less.

Front

Explain the concept of gravitational pull in relation to tides.

Back

Gravitational pull is the force exerted by the Moon and the Sun on Earth's water, causing tides.
