Erosional landforms

What process leads to the formation of a wave-cut notch in cliffs?

• Hydraulic action and abrasion

• Biological weathering

• Freeze-thaw action

• Chemical weathering

What is a common feature of shore platforms in chalk or limestone geology?

• Sand dunes

• Rock pools like pot-holes

• Coral reefs

• Volcanic rocks

What causes headlands and bays to form in a discordant coastline?

• Uniform rock resistance

• Bands of resistant and less resistant rock

• Volcanic activity

• Tectonic plate movement

What effect does wave refraction have on headlands?

• It reduces erosion

• It concentrates wave force onto the sides

• It creates sandbars

• It forms coral reefs

What geological process contributes to the formation of caves and arches on concordant coastlines?

• Sedimentation

• Hydraulic action and abrasion

• Volcanic activity

• Tectonic uplift

What happens to the top of an arch over time due to erosion and weathering?

• It becomes a mountain

• It collapses under gravity

• It forms a valley

• It turns into a plateau

What is left after the collapse of an arch on a headland?

• A cave

• A stack of rock

• A lagoon

• A sand dune

What is the main cause of erosion in geos?

• Wind erosion

• Hydraulic action

• Glacial movement

• Biological activity

What is a geo?

• A vertical shaft from a cave

• A tunnel-like cave running inland

• A type of rock formation

• A type of plant

What happens when the roof of a tunnel-like cave collapses?

• It forms a blowhole

• It creates a waterfall

• It becomes a mountain

• It forms a river
