Coastal Geography Concepts Assessment

The video explores the dynamics of shorelines, focusing on how ocean forces like waves, currents, and tides shape and erode them. It discusses the composition of beaches, the impact of longshore currents, and the formation of features like spits and lagoons. Human interventions such as sea walls and jetties are examined for their role in coastal protection. The video also addresses the implications of rising sea levels due to climate change and how they affect coastal areas.

What is the area between the highest water level during a storm and the lowest water level at low tide called?

• The bay

• The headland

• The beach

• The ocean

How do waves behave when they encounter a narrow constriction?

• They move in a straight line

• They stop moving

• They refract and bend around corners

• They increase in speed

Which coastal feature is formed by the continuous carving of water into rock, creating a structure that doesn't go all the way through?

• Sea cave

• Arch

• Lagoon

• Sea stack

What causes longshore currents to form?

• Waves hitting the shore at a perpendicular angle

• Waves hitting the shore at an angle

• Tides rising and falling

• Currents moving parallel to the shore

What is a spit in coastal geography?

• A narrow strip of land connecting two larger land masses

• A deep underwater trench

• A sandbar that connects the mainland to an island

• A narrow strip of sand extending into the water

What is the primary purpose of a sea wall?

• To create new beaches

• To increase the speed of longshore currents

• To protect structures from wave damage

• To enhance the beauty of the coastline

How do groins help in managing beach sand?

• By allowing sand to move freely along the coast

• By preventing sand from being carried away by currents

• By increasing the speed of incoming waves

• By creating new sand dunes

What is the effect of rising sea levels on coastal cities?

• They are at risk of flooding

• They experience increased erosion

• They gain more land area

• They become more accessible for tourism

What is an emergent coast?

• A coastline that is sinking

• A coastline that is rising

• A coastline that is eroding

• A coastline that is stable

What natural process can cause a coastline to rise?

• Tectonic uplift

• Wave action

• Sediment deposition

• Erosion
