Shoreline Erosion and Deposition

Imagine you are at a beach. What would you consider as shoreline erosion?

• Sudden collapse of the beach or land along the shoreline due to activities like construction or mining.

• Formation of new beach or land along the shoreline due to natural forces like wind or water currents.

• Gradual wearing away of the beach or land along the shoreline due to natural forces like waves or tides.

• Gradual buildup of the beach or land along the shoreline due to human activities like sandbagging or beach nourishment.

During a field trip, you noticed a hillside where new soil and rocks were being added. What process is this an example of?

• The process of melting ice or snow into water.

• The process of removing sediments, soil, or rocks from a landform or landmass.

• The process of adding sediments, soil, or rocks to a landform or landmass.

• The process of weathering and erosion.

Imagine you are on a vacation and you see a long, narrow island that is parallel to the mainland and separated from it by a lagoon or bay. What would you call this?

• You would call it a type of mountain range.

• You would call it a barrier island.

• You would call it a man-made structure used to block water flow.

• You would call it a type of coral reef.

Imagine you are at a beach. What natural phenomenon would you observe that causes shoreline erosion?

• People playing and running around

• Waves crashing onto the shore

• The movement of tides

• Rain falling on the beach

During a geography field trip, you come across a narrow coastal landform. Your teacher asks you, 'What is this landform called, which is created by sediment deposition from longshore drift?'.

• Is it a term used to describe a quick and forceful expulsion of saliva from the mouth?

• Is it a type of food that is roasted over an open fire?

• Is it a small pointed object used for holding meat while it is being cooked?

• Is it a Barrier spit?

A coastal town is facing severe shoreline erosion. As a town planner, what would be your recommendation to prevent further erosion?

• Dumping more sand on the beach

• Constructing more buildings near the shoreline

• Implementing measures such as building seawalls, planting vegetation, and creating offshore breakwaters.

• Removing vegetation along the shoreline
