Yr7 Tidal Cycle

What causes the rise and fall of water levels in the oceans?

• The Moon's rotation

• The Earth's orbit around the Sun

• The Sun's rotation

• The gravitational pull of the Moon

Answer explanation

The rise and fall of water levels in the oceans are caused by the gravitational pull of the Moon.

What phenomenon creates the regular pattern of tides on Earth?

• Clouds

• Wind

• Rain

• Tidal forces

Answer explanation

Tidal forces create the regular pattern of tides on Earth by exerting gravitational pull on the oceans.

Why do we experience high and low tides throughout the day?

• Because of the Earth's rotation

• Because of the Moon's rotation

• Because of the Sun's rotation

• Because of the Moon's orbit

Answer explanation

We experience high and low tides throughout the day because of the Moon's orbit.

What causes the gravitational pull on the Earth's oceans?

• The Moon's rotation

• The Earth's rotation

• The Sun's rotation

• The Moon's orbit

Answer explanation

The gravitational pull on the Earth's oceans is caused by the Moon's rotation, which creates the tides.

What happens to the water levels in the oceans during high tide?

• They rise

• They stay the same

• They decrease

• They disappear

Answer explanation

During high tide, the water levels in the oceans rise due to the gravitational pull of the moon and the sun.

What causes the bulges of water that create high tides?

• The Moon's orbit around the Earth

• The Earth's orbit around the Sun

• The Earth's rotation around the Sun

• The Sun's orbit around the Earth

Answer explanation

The bulges of water that create high tides are caused by the Moon's orbit around the Earth, which creates gravitational forces that pull the water towards the Moon.

Why do we experience two high tides and two low tides each day?

• Because of the Earth's rotation

• Because of the Moon's rotation

• Because of the Sun's rotation

• Because of the Earth's orbit

Answer explanation

The correct answer is because of the Moon's rotation, which causes the gravitational pull that creates the tides.

What causes the gravitational pull that creates tides on Earth?

• The Moon's rotation

• The Earth's rotation

• The Sun's rotation

• The Moon's orbit

Answer explanation

The gravitational pull that creates tides on Earth is caused by the Moon's rotation.

What happens to the water levels in the oceans during low tide?

• They rise

• They stay the same

• They decrease

• They disappear

Answer explanation

During low tide, the water levels in the oceans decrease as the gravitational pull of the moon causes the water to recede from the shore.

What phenomenon is responsible for the regular pattern of tides we observe?

• Wind

• Rain

• Tidal forces

• Clouds

Answer explanation

Tidal forces are responsible for the regular pattern of tides we observe.
