Tides

Tide:

• The regular rise and fall of ocean surfaces.
• Tides are caused by the gravitational pull of the Moon and Sun.

Tidal Bulge:

• A bulge of water formed by the pull of the Sun and Moon’s gravity.
• Typically there are two tidal bulges. One is located on the side of Earth that faces the Moon. The other is on the opposite side of Earth, away from the Moon.
• When a location on Earth’s surface rotates into a tidal bulge, it experiences high tide.

High Tide:

• The maximum height reached by a rising tide.

Low Tide:

• The minimum height of a falling tide.

Gravity:

• The force of attraction between all objects in the universe.

Spring Tide:

• A tide with a relatively large difference between high and low tide.
• Spring tides occur when the Sun, Moon, and Earth are aligned (in a line).

Neap Tide:

• A tide with a relatively small difference between high and low tide.
• Neap tides occur when the Sun, Moon, and Earth form a right angle.
