Neap, spring, high, and low are all types of

Tides

Explanation:

Tides are referred to the rise and fall of sea level. This happens due to the gravitational pull of moon and sun and rotation of Earth.

High tides occur on the side closest and farthest from moon.

Low tides occur on the other sides.

Spring tides and Neap tides occur twice a month. Spring tides occur when the sun, the earth and the moon align in a straight line i.e. during new moon and full moon. Highest high tides and lowest low tides occur at this time.

Neap tides occur during the first and third quarter of moon. At this time moderate tides occur.

Thus, Neap, spring, high and low are all types of tides.
