Understanding Longshore Drift and Coastal Erosion

This video explains the Longshore drift process, where waves move sand and debris along a beach. It describes how waves hitting the beach at an angle cause sand particles to be transported, altering the beach's shape over time. Groins are used to prevent erosion by trapping sand. The video also provides additional resources for further learning.

What is the primary cause of waves hitting a beach at an angle, leading to Longshore Drift?

• The time of day

• The temperature of the water

• The direction of the wind

• The shape of the coastline

In the Longshore Drift process, what happens to sand particles during the backwash?

• They are pulled straight back into the sea

• They are deposited in the ocean

• They remain stationary

• They are pushed further up the beach

What is the term used to describe the movement of sand and debris along the beach due to wave action?

• Tidal flow

• Longshore Drift

• Beach erosion

• Wave refraction

What is the effect of small waves on sand particles?

• They push sand particles into the ocean

• They move sand particles along the beach

• They do not affect sand particles

• They cause sand particles to settle

How do groins help in preventing beach erosion?

• By redirecting ocean currents

• By lowering sea levels

• By increasing wave energy

• By trapping sand particles on the beach

What material are groins typically made from?

• Plastic

• Metal

• Wood or stone

• Concrete

What can happen to beaches over time due to Longshore Drift?

• They can become more stable

• They can become less sandy

• They can change shape or disappear

• They can become larger

What is the main purpose of the video tutorial?

• To explain the Longshore Drift process

• To describe weather patterns

• To teach about ocean currents

• To discuss marine life
