Coastal Erosion and Mass Movements Quiz

Study Figure 1. State the wind direction that major storms often come from.

• North

• South

• East

• West

Study Figure 1. Name the UNESCO World Heritage Site that this coast is a part of.

• Great Barrier Reef

• Jurassic Coast

• Galápagos Islands

• Ha Long Bay

Study Figure 5. Which of the following are ways in which the weather can cause mudflows?

• Heavy rainfall saturates the soil, leading to instability.

• Strong winds erode the topsoil, causing it to slide.

• Rapid snowmelt increases water content in the soil.

• High temperatures cause soil expansion and movement.

Study Figure 7 on page 5, which shows coastal management work taking place at West Bay. Identify three main land uses that appear to be at risk from coastal erosion.

• Residential areas, agricultural land, and recreational facilities

• Industrial zones, shopping centers, and highways

• Forests, mountains, and rivers

• Deserts, lakes, and urban parks

Coastal defences on this cliff and beach can reduce the risks of mass movement by:

• Preventing erosion and stabilizing the cliff

• Increasing the rate of sediment deposition

• Enhancing the natural beauty of the coastline

• Promoting tourism in the area

Climate change is likely to increase the size and frequency of mass movements along the coast because:

• It leads to rising sea levels and increased erosion.

• It causes a decrease in coastal vegetation.

• It results in more frequent and intense storms.

• It reduces the amount of sediment available for coastal protection.

What should an information leaflet include for people living in towns at risk from mass movements?

• Explanation of what mass movements are

• Signs to look out for

• How the cliffs could be managed

• All of the above

Which type of graph should be used to illustrate the figures with months on the x-axis, rainfall as bars, and the number of landslides as a line?

• Bar graph with line overlay

• Pie chart

• Scatter plot

• Histogram

Describe what pattern your graph shows.

• Linear pattern

• Exponential pattern

• Cyclical pattern

• No discernible pattern

Suggest reasons for the pattern shown. How strong is the correlation between the number of landslides and rainfall total for the period shown?

• Very strong correlation

• Moderate correlation

• Weak correlation

• No correlation
