What causes tides on Earth?

Back

Tides are caused by the gravitational pull of the Moon and the Sun on Earth's oceans. The Moon has a greater effect because it is closer to Earth.

Front

What is high tide?

Back

High tide is the point in the tidal cycle when the water level is at its highest due to the gravitational pull of the Moon and the Sun.

Front

What is low tide?

Back

Low tide is the point in the tidal cycle when the water level is at its lowest, occurring between high tides.

Front

How often do tides occur?

Back

Tides typically occur twice a day, with two high tides and two low tides in a 24-hour period.

Front

What is the role of the Sun in tides?

Back

The Sun also affects tides, but its influence is less than that of the Moon due to its greater distance from Earth.
