Coastal Landscapes Review #4

What causes a spring tide?

• When the moon and sun's gravity are in alignment

• When the moon and sun's gravity are at 90 degrees to each other

How does tidal range affect the coastline?

• It creates a larger or smaller zone of attack for waves

• It can flood areas

• It doesn't move large volumes of sediment

Why is the land and sea at the equator warmer?

• It receives more intense solar radiation

• It is sunnier

• It is closer to the sun

How do ocean currents affect the coastline?

• They regulate temperature therefore influence weathering

• They regulate temperature therefore influence erosion

• They move vast quantities of sediment

What forms ocean currents?

• Wind

• Wave

• Tide

• Gravity

What is the ocean current near the UK?

• Warm and at the surface

• Warm and deep water

• Cold and at the surface

• Cold and deep water

What two weathering processes are more likely at the UK because of the warm ocean currents?

• Physical

• Chemical

• Biological

What weathering process is more likely where there are cold ocean currents?

• Physical

• Chemical

• Biological
