Exploring Coastal Environments

What is coastal erosion?

• Coastal erosion is the process of the coastline being worn away by natural forces.

• The process of building new land along the coast.

• A method of increasing coastal vegetation.

• The study of marine life in coastal areas.

Name one process of coastal erosion.

• Coastal deposition

• Hydraulic action

• Wave refraction

• Sedimentation

How does wave action contribute to coastal erosion?

• Wave action strengthens coastlines by depositing more sand.

• Wave action only affects marine life, not the coastline.

• Wave action erodes coastlines by breaking down rocks and transporting sediments.

• Wave action creates new landforms without eroding coastlines.

What is not a type of coastal landforms?

• Headland

• Reef

• Beach

• Bay

Describe a cliff and how it is formed.

• A cliff is a rock that is made in the mountains.

• A cliff is a flat area of land formed by volcanic activity.

• A cliff is a steep face of rock formed by erosion and weathering processes.

• A cliff is a gentle slope created by sediment deposition.

What is a beach and how does it form?

• A beach is found in a freshwater pond surrounded by trees.

• A beach is a marine landform and an accumulation of sand and sediment.

• A beach is a flat area of sand covered in grass.

• A beach is a landform created by volcanic activity.

What human activities can lead to coastal erosion?

• Building artificial reefs

• Mining, deforestation, and urban development.

• Planting trees along the coast

• Creating wildlife reserves

How does urban development impact coastlines?

• Urban development negatively impacts coastlines by increasing erosion, disrupting sediment flow, and causing habitat loss.

• Urban development enhances coastal habitats and biodiversity.

• Urban development has no effect on coastal erosion.

• Urban development improves sediment flow along coastlines.

What are some common soft engineering strategies?

• Groynes

• Mangroves

• Sea Walls

• Beach nourishment

Define hard engineering in coastal management.

• Hard engineering focuses on community education about coastal issues.

• Hard engineering uses natural materials to enhance coastal ecosystems.

• Hard engineering promotes the use of soft solutions like beach nourishment.

• Hard engineering involves the construction of physical structures to protect coastlines from erosion and flooding.
