Tides

Front

What are tides?

Back

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

Front

What causes high tides?

Back

High tides occur when the gravitational pull of the moon and sun is strongest on a particular side of the Earth.

Front

What is a spring tide?

Back

A spring tide is a tide that occurs when the sun, moon, and Earth are aligned, resulting in higher high tides and lower low tides.

Front

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 lower high tides and higher low tides.

Front

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 on Earth.

Front

Why do we experience different tide heights?

Back

Different tide heights are caused by the varying gravitational pull of the moon and sun at different positions relative to Earth.

Front

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 effect of the sun on tides?

Back

The sun also affects tides, but its effect is less than that of the moon due to its greater distance from Earth.

Front

What is tidal range?

Back

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