Coastal Landforms Flashcards
(23 cards)
What is a headland?
A headland is a coastal landform that extends into a body of water, typically characterized by steep cliffs.
What is a bay?
A bay is a body of water partially enclosed by land.
True or False: A cave is formed by the erosion of rock by water.
True
What is an arch in geological terms?
An arch is a natural rock formation that has an opening beneath it, formed by erosion.
What are stacks?
Stacks are vertical columns of rock that have been isolated from the mainland due to erosion.
What is the name of a coastal feature formed when a stack collapses, leaving behind a small rock pinnacle.
stump
What is a spit?
A spit is a narrow landform of sand or shingle that extends into a body of water from the mainland.
What is a bar?
A bar is a submerged or partly submerged ridge of sand or gravel that forms across a river mouth or along a coastline.
What is a tombolo?
A tombolo is a landform that connects an island to the mainland, typically formed by sediment deposition.
What are sand dunes?
Sand dunes are hills of sand formed by the wind, often found in desert environments or along coastlines.
True or False: Headlands are typically formed by sediment deposition.
False
What process primarily contributes to the formation of caves?
Erosion, particularly by water, contributes to cave formation.
What is the primary force that shapes headlands and bays?
Wave erosion
What type of shoreline feature is formed when waves erode the base of a cliff?
A cave can form when waves erode the base of a cliff.
True or False: Sand dunes can migrate due to wind action.
True
What happens to a stack when it erodes further?
It eventually collapses and may form a stump.
What is the difference between a bar and a spit?
A bar is a ridge across a river mouth, while a spit extends from the mainland into water.
Multiple Choice: Which feature is formed by the deposition of sediment? A) Cave B) Arch C) Spit
C) Spit
What role do waves play in the formation of coastal features?
Waves erode land and deposit sediment, shaping features like headlands, bays, and spits.
Fill in the blank: A __________ is a landform that can be created by the accumulation of sand in coastal areas.
sand dune
What is the main characteristic of a tombolo?
A tombolo connects an island to the mainland.
True or False: Stacks are usually formed from softer rock.
False
What is the primary cause of the erosion that forms caves?
The primary cause is the action of water, especially acidic water, on soluble rock.
