What happens during low tide?

When the moon's gravity is pulling on one side creating high tide, the side where the moon is not pulling become low.

What are the terrestrial planets?

Within the Solar System, the terrestrial planets are the inner planets closest to the Sun. The terms "terrestrial planet" and "telluric planet" are derived from Latin words for Earth (Terra and Tellus), as these planets are, in terms of composition, "Earth-like". Mercury, Venus, Earth, Mars

How do spring and neap tides occur?

Spring tides occur when the moon, earth, and sun are in alignment. During the full and new moon faces. Neap tides occur when the sun, moon, and earth form a right angle.

When is gravity stronger?

The greater the mass and the closer the distance of two objects.

How is the moon's gravity able to create high and low tides?

The moon is revolving more slowly than the earth is rotating, which allows the moon's gravity to pull on the earth's ocean waters creating a bulge during a high tide.

What happens during high tide?

The moon's gravity is pulling the ocean water into a bulge.

Why do we always see the same side of the moon?

The reason we always see the same side of the moon is because the moon rotates at the same speed at which it revolves.

What happens during a total solar eclipse?

The sun, moon, and earth are aligned and the moon is blocking the earth from the sun. The daylight will become dark.
