What causes high and low tides?

Back

High and low tides are caused by the gravitational pull of the moon and the sun on Earth's oceans, leading to bulges of water.

What is a neap tide?

Back

A neap tide occurs when the sun and moon are at right angles to each other, resulting in the least difference between high and low tides.

How often do tides occur?

Back

Tides typically occur twice a day, with two high tides and two low tides.

Front

What is the role of the moon in tides?

Back

The moon's gravitational pull is the primary force that causes tides, creating bulges of water on the side of the Earth facing the moon.

Front

What is the role of the sun in tides?

Back

The sun also exerts a gravitational pull on Earth's oceans, influencing the height of tides, but its effect is less than that of the moon.

What is the difference between high tide and low tide?

Back

High tide is the maximum level of the sea, while low tide is the minimum level of the sea.

Front

What is the lunar cycle?

Back

The lunar cycle is the 29.5-day cycle of the moon's phases, which affects the timing and height of tides.
