What is a Neap Tide?

Back

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

Front

What is a Spring Tide?

A Spring Tide is a tide that occurs during a New Moon or Full Moon when the sun and moon are aligned, resulting in the greatest difference between high and low tides.

Front

When do Neap Tides occur?

Back

Neap Tides occur during the first and third quarters of the moon, also known as Half Moons.

Front

Which celestial body has the greatest gravitational effect on tides?

Back

The Moon has the greatest gravitational effect on tides, followed by the Sun.

Front

What is a Tidal Bore?

Back

A Tidal Bore is a strong tide that pushes up a river against the current, creating a wave that can be surfed.

Front

What is the difference between High Tide and Low Tide?

Back

High Tide is the maximum level of the sea reached at a given time, while Low Tide is the minimum level of the sea.

Front

What causes tides?

Back

Tides are caused by the gravitational pull of the moon and the sun on Earth's oceans.

Front

What is the role of the Sun in tidal movements?

Back

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

Front

What is the tidal range?

Back

The tidal range is the difference in height between high tide and low tide.

Front

What is a tidal cycle?

Back

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