Coastal Geography Concepts

Hannah discusses shoreland erosion and deposition, explaining how natural processes shape shorelines, beaches, and various coastal features. She defines key terms like shoreline, beach, and currents, and describes the formation of sea stacks, arches, caves, headlands, and wave-cut terraces.

What is shoreland erosion primarily responsible for?

• Removing sediments from the shoreline

• Building new landforms

• Creating new water bodies

• Increasing water levels

How is a beach defined in relation to the ocean?

• A rocky area far from water

• A sandy or pebbly area between high and low water marks

• A grassy area near a lake

• A muddy area in a river

What is another term for an undertow current?

• Rip current

• Ocean swell

• Longshore current

• Tidal wave

Which current moves parallel to the shore?

• Longshore current

• Undertow current

• Tidal current

• Deep ocean current

What are sea stacks?

• Underwater caves

• Tall waves during a storm

• Offshore columns of resistant rock

• Large piles of sand on the beach

How do sea arches form?

• By volcanic activity

• By the accumulation of sand

• Through the deposition of sediments

• Through wave action eroding sea caves

What are sea caves composed of?

• Volcanic ash

• Igneous rock

• Sedimentary rock

• Metamorphic rock

What shape do headlands typically have?

• Triangular

• Finger-shaped

• Circular

• Square

What is a wave-cut terrace?

• A deep ocean trench

• A sandy beach

• A nearly level platform beneath the water at the base of a cliff

• A steep cliff above the water
