Coastal Landscapes #5

Weathering is the...

• removal of material

• breakdown of material in its place (in situ)

• physical breakdown of material

Which type of weathering is more common with lower temperatures and precipitation?

• Physical weathering

• Chemical weathering

Which type of mass movement is most likely on steep, unvegetated slopes?

• Rockfall

• Mudflow

• Solifluction

• Landslide

Which of these descriptions would result in the highest energy waves in South West England?

• Stormy conditions 20km from the coastline for 24 hours

• Hurricane conditions in the mid-Atlantic Ocean for 10 days

• Calm conditions in the Atlantic Ocean for 20 days

How are waves formed?

• The transfer of kinetic energy from the wind due to friction with the sea surface

• The transfer of potential energy from the wind due to friction with the sea surface

• The transfer of energy from the wind due to friction with the sea surface

The _____ _____ is the difference between the levels of ocean water at high tides and low tides. That range depends on the sun-Earth-moon;s position.

• ocean waves

• mountain level

• sea level

• tidal range

The intertidal zone is...

• The coastal area between mean high water (tide) and mean low water (tide)

• The space exposed between tides

• Difference between high tide and low tide

Larger tidal ranges will...

• Have low levels of transportation of sediment

• Help to erode more of the coastline (have a larger 'attack zone')

• Move more slowly

• Reduce weathering processes

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
