Coasts Flashcards
True or False: Longshore drift is a process that moves sand and sediment along the coastline.
True
Fill in the blank: Longshore drift occurs due to the angle of ________ and the direction of waves.
wave approach
What are the primary factors influencing coastal erosion?
Wave action, tidal forces, and human activities.
Multiple Choice: Which of the following is NOT a factor that affects longshore drift? A) Wave direction B) Wind speed C) Coastal vegetation
C) Coastal vegetation
What is the role of longshore currents in coastal processes?
Longshore currents transport sediment parallel to the shore, contributing to longshore drift.
True or False: Longshore drift can lead to the formation of features such as spits and bars.
True
Short Answer: Name one human activity that can disrupt the natural process of longshore drift.
Construction of groins or jetties.
What is a spit in coastal geography?
A spit is a narrow landform that extends from the mainland into the water, formed by longshore drift.
Multiple Choice: Which type of coastline is most affected by longshore drift? A) Rocky B) Sandy C) Cliff
B) Sandy
Fill in the blank: The angle at which waves hit the shore is known as the ________ angle.
wave incidence
What is the effect of sea level rise on coastal areas?
Sea level rise can lead to increased flooding, erosion, and loss of habitat in coastal areas.
True or False: Coastal management strategies often include beach nourishment.
True
What is the difference between erosion and deposition in coastal environments?
Erosion involves the removal of sediment, while deposition is the accumulation of sediment in a new location.
