What are tides?

Back

Tides are the regular rise and fall of sea levels caused by the gravitational forces exerted by the moon and the sun on the Earth.

What causes high tides?

Back

High tides occur when the bulge of water is on the side of the Earth closest to the moon, due to the moon's gravitational pull.

What are spring tides?

Back

Spring tides are the highest and lowest tides that occur when the sun, Earth, and moon are aligned, typically during new and full moons.

Back

Neap tides are the lower high tides and higher low tides that occur when the sun and moon are at right angles relative to the Earth, typically during the first and third quarter moons.

What is the gravitational effect of the sun on tides?

Back

The sun's gravitational pull also affects tides, but its effect is less than that of the moon, leading to variations in tide heights.

Front

What is a tidal cycle?

Back

A tidal cycle refers to the pattern of rising and falling sea levels, typically occurring twice a day.

Front

What is the role of the moon in tidal changes?

Back

The moon's gravitational pull creates bulges in the Earth's oceans, leading to high tides on the side facing the moon and the opposite side.
