Which human activity is a major contributor to coastal erosion?

Beach Nourishment
Mangrove Restoration
Seawall Construction
Sustainable Fishing

How does the construction of groynes affect coastal erosion?

It reduces erosion by trapping sediment.
It increases erosion by disrupting sediment transport.
It has no significant impact on erosion.
It enhances sediment deposition, leading to beach growth.

What is the primary cause of accelerated coastal erosion in recent decades?

Increased Sea Level Rise
Deforestation in Coastal Areas
Unsustainable Sand Mining
Overfishing

How does the removal of sand from beaches impact coastal erosion?

It reduces erosion by lowering the beach profile.
It increases erosion by disrupting sediment balance.
It has no significant impact on erosion.
It enhances sediment deposition, leading to beach growth.

Which human activity can contribute to the loss of coastal wetlands?

Mangrove Restoration
Dredging for Navigation Channels
Beach Nourishment
Sustainable Fishing

How does the construction of jetties affect coastal erosion?

It reduces erosion by trapping sediment.
It increases erosion by disrupting sediment transport.
It has no significant impact on erosion.
It enhances sediment deposition, leading to beach growth.

What is the primary consequence of coastal erosion?

Increased Biodiversity
Enhanced Coastal Tourism
Loss of Coastal Habitats
Improved Water Quality

How does the construction of breakwaters affect coastal erosion?

It reduces erosion by dissipating wave energy.
It increases erosion by disrupting sediment transport.
It has no significant impact on erosion.
It enhances sediment deposition, leading to beach growth.

Which human activity can contribute to increased coastal erosion due to the removal of natural vegetation?

Mangrove Restoration
Beach Nourishment
Deforestation in Coastal Areas
Sustainable Fishing

How does the construction of seawalls affect coastal erosion?

It reduces erosion by protecting the shoreline.
It increases erosion by disrupting sediment transport.
It has no significant impact on erosion.
It enhances sediment deposition, leading to beach growth.

What is the primary cause of coastal erosion in areas with minimal human activity?

Increased Sea Level Rise

Natural Geological Processes

How does the construction of offshore breakwaters affect coastal erosion?

It reduces erosion by dissipating wave energy.
It increases erosion by disrupting sediment transport.
It has no significant impact on erosion.
It enhances sediment deposition, leading to beach growth.

Which human activity can contribute to increased coastal erosion due to the alteration of sediment transport patterns?

Mangrove Restoration
Beach Nourishment
Construction of Groynes and Jetties
Sustainable Fishing

How does the construction of artificial reefs affect coastal erosion?

It reduces erosion by dissipating wave energy.
It increases erosion by disrupting sediment transport.
It has no significant impact on erosion.
It enhances sediment deposition, leading to beach growth.

What is the primary goal of beach nourishment as a coastal erosion management strategy?

To restore lost beach sand and protect the shoreline.
To increase the height of coastal dunes.
To create new coastal habitats for wildlife.
To improve water quality in coastal areas.
