Coastal Geography Concepts Assessment

The video tutorial explains coastal features formed by longshore drift, focusing on spits, bars, and tombolos. It describes how beach material is transported along the coast, forming spits when the land ends. The video also covers the development of salt marshes behind spits, where sediment and organic material accumulate, creating new land. Finally, it discusses the formation of bars and tombolos, where spits connect to other landmasses, forming lagoons.

What is the primary process responsible for the movement of beach material along the coastline?

• Erosion

• Longshore drift

• Deposition

• Weathering

What happens to beach material when the land ends at a river mouth?

• It stops moving

• It forms a cliff

• It creates a delta

• It continues into the sea as a spit

What is a spit?

• Beach material extending into the sea

• A river formation

• A type of fish

• A type of plant

What type of plants begin to grow in the sheltered area behind a spit?

• Halophytes

• Mangroves

• Cacti

• Conifers

What is the main reason salt marshes become higher over time?

• Erosion by waves

• Deposition of organic material and sediment

• Increased rainfall

• Earthquakes

What human activities might occur on land formed behind a spit?

• Mining

• Farming and recreational activities

• Building skyscrapers

• Fishing

What natural event can still flood a salt marsh?

• Volcanic eruptions

• Droughts

• High tides or storms

• Earthquakes

What is a bar in coastal geography?

• A type of fish

• A river formation

• A type of plant

• A spit that connects to another piece of land

What is a tombolo?

• A river delta

• A spit that connects to an island

• A mountain range

• A type of tree

Why don't spits usually form across large rivers?

• The land is too flat

• The water is too shallow

• The river's discharge is too strong

• There is too much vegetation
