Tides

What would happen to the ocean if there wasn't a moon orbiting Earth?

• The ocean would be equally distributed around the earth and there would be no low or high tide

• The ocean would continually be in a state of low tide

• The ocean would continually be in a state of high tide

• No moon would cause the sun to dry up the ocean leaving no water on planet Earth

The Earth experiences a strong gravitational pull towards the moon. It is so strong it causes the water in the ocean to 'bulge' outwards towards the moon. What type of tides are formed in other areas where there is no bulge?

• No tides are formed

• High tide is formed

• Low tides are formed

• The ocean freezes

Why does the moon have a stronger influence on the Earth, than the sun, causing tides?

• The moon is larger than the sun, causing greater gravitational pull on the Earth and ocean.

• The moon is much closer to the Earth than the sun, causing a greater gravitational pull on the Earth and ocean

• The moon is further away from the Earth than the sun, causing a greater gravitational pull

Tides that have the largest daily tidal range occur during the new-moon and full moon phases (every 14 days). This happens when the earth, moon and sun are aligned. For example the moon is between the earth and the sun; or the earth is between the moon and the sun. What type of tide is this called?

• Tidal wave

• Neap tide

• Summer tide

• Spring tide

A neap tide occurs when the moon and the sun are at right angles with the Earth - When the moon is at its first and third quarter. This causes

• A tidal wave

• Smaller tidal range than average and known as the weakest tides

• Higher tidal range than average and known as the strongest tides

• King tides; when there is greatest difference between high and low tide
