Coastal Erosion | Baamboozle - Baamboozle | The Most Fun Classroom Games!

What happens to sediments removed from one part of a shoreline?

They may be transported and deposited elsewhere

They vanish

They transform into magma

Ocean currents play a role in moving sediment along the coast over time.

True

False

Currents only move water, not sediment

What natural feature can help slow coastal erosion?

Vegetation like mangroves

Concrete jets

Plastic barriers

Erosion does not always mean permanent land loss

sometimes material is deposited elsewhere.

True

False

Erosion always destroys everything

Which of these is NOT caused by coastal erosion?

Underground oil formation

Loss of beaches

Habitat destruction

_______ can accelerate erosion by increasing wave energy and flooding low coastal areas.

Climate change

Cloud formation

Soil harvesting

Why does coastal erosion occur?

Because waves and currents remove shoreline material

Because mountains rise

Because the sun melts ice

Which of these is an example of coastal protection?

Beach nourishment

Deforestation

River mining

Buildings and roads near the shoreline are at risk because erosion removes supporting land.

True

False

It makes the land more stable

Which feature is formed by continued coastal erosion?

Sea arches and stacks

Volcano craters

River deltas

What term describes the movement of sediment parallel to the shoreline?

Longshore drift

Friction decay

Tidal shuffle

When heavy rainfall increases surface water flow toward the sea, it can contribute to erosion.

True

False

Rainfall has no effect

Waves that deposit more sand than they remove are called what?

Constructive waves

Destructive waves

Explosive waves

Which natural force compresses air into cracks in coastal rock and helps break it apart?

Hydraulic action

Magnetism

Glacial carving

Climate change is expected to increase coastal erosion through higher sea levels.

True

False

It decreases sea levels

Storm surges associated with severe weather can dramatically accelerate coastal erosion.

True

False

A storm surge always builds up beaches

What is the loss of land along the coast called?

Coastal erosion

Ocean expansion

Volcanic intrusion

Which of these human actions can worsen coastal erosion?

Sand mining from beaches

Building coral reefs

Planting mangroves

A coastline can slowly retreat over years due to the net removal of sediment.

True

False

It becomes permanently fixed

Which of the following is NOT a cause of coastal erosion?

Tree planting on dunes

Storm surge

Strong wind

Waves, currents, and wind reshape shorelines by removing and depositing sediment over time.

True

False

They only affect underwater landscapes

Deposition is the opposite of coastal erosion and involves materials being dropped along the shore.

True

False

It means the sea level rises permanently

Human activities like coastal development can increase erosion by disrupting sediment flow.

True

False

It prevents all erosion entirely

What kind of wave action can most rapidly erode a cliff face?

Destructive waves

Silent waves

Constructive waves

Abrasion in coastal erosion refers to rocks and sediment being hurled against cliffs by waves.

True

False

It refers to wind blowing inland

Which of these is a natural process that changes the coastline over time?

Hydraulic action

Car engine exhaust

Asteroid impacts

Sea level rise causes coastal erosion because it increases wave impact on the shore.

True

False

It decreases wave energy

What term describes sand and soil being carried along the shore by current and wave action?

Longshore drift

Plate tectonics

Earthquake uplift

Which of the following primarily contributes to coastal erosion?

Wave action

Forest growth

Mountain formation

Coastal erosion is the wearing away of land along the coastline by waves, currents, tides, and wind.

The wearing away of land by the sea

The building up of land from deposited sediment

The sinking of land due to earthquakes
