Coastal Erosion Quiz

What is coastal erosion?

• The process by which waves, wind, and tides wear away the land along a coast.

• The process by which rocks form along a coast.

• The process by which sand dunes form along a coast.

• The process by which coastal habitats are created.

What are the primary drivers of coastal erosion?

• Hydraulic pressure, friction, and dissolution.

• Wind, tides, and rain.

• Waves, currents, and sediment.

• Temperature, humidity, and pressure.

What is hydraulic pressure?

• The force exerted by water as it moves along the coast.

• The force exerted by wind as it moves along the coast.

• The force exerted by tides as they move along the coast.

• The force exerted by rain as it falls along the coast.

What is attrition?

• The process by which waves and currents carry sediment and debris along the coast.

• The process by which waves crash against cliffs or rocky outcroppings.

• The process by which seawater can dissolve certain types of rock and sediment.

• The process by which waves pick up rocks and other debris and hurl them against the coastline at high speeds.

What is abrasion?

• The process by which seawater can dissolve certain types of rock and sediment.

• The process by which waves crash against cliffs or rocky outcroppings.

• The process by which waves and currents carry sediment and debris along the coast.

• The process by which waves pick up rocks and other debris and hurl them against the coastline at high speeds.

What is corrosion?

• The process by which seawater can dissolve certain types of rock and sediment.

• The process by which waves crash against cliffs or rocky outcroppings.

• The process by which waves and currents carry sediment and debris along the coast.

• The process by which waves pick up rocks and other debris and hurl them against the coastline at high speeds.

How do these different processes interact with each other?

• They operate independently of each other.

• They interact in complex ways, often leading to more dramatic erosion and landscape changes.

• They interact in ways that are predictable and easily understood.

• They interact in ways that do not contribute to coastal erosion.

What are the effects of coastal erosion?

• Loss of land, loss of habitats for a variety of plant and animal species, and economic impacts.

• Increased flooding, decreased habitat availability, and increased biodiversity.

• Increased tourism, decreased property values, and decreased biodiversity.

• Increased economic growth, increased property values, and increased habitat availability.

What are some strategies for reducing erosion?

• Building seawalls, planting vegetation to stabilize the soil, and dredging sediment from rivers and other sources.

• Building homes and businesses further inland, reducing water use, and increasing carbon sequestration.

• Reducing pollution, increasing public transportation, and reducing waste.

• None of the above.

What is the importance of managing coastal erosion?

• To protect human communities and the environment, and to recognize that some erosion is a natural and necessary part of coastal ecosystems.

• To increase economic growth and property values, and to reduce biodiversity loss.

• To increase tourism, reduce flooding, and increase habitat availability.

• To protect natural resources, increase ecological resilience, and decrease climate change impacts.
