Erosional Landforms Flashcards
(18 cards)
Headland definition
Section of land that sticks out into the sea
Headland formation
Formed when harder rock erodes slower than surrounding softer rock leaving it jutting out
Bay definition
Inward curve in the coastline
Bay formation
Softer rock eroded faster due to hydraulic action and abrasion forming sheltered inlet
Cliff definition
Steep or vertical rock face along coast
Cliff definition
Formed by the wave erosion at base causing collapse retreat of the upper cliff
Wave cut notch definition
Hollow at the base of a cliff
Wave cut notch formation
Created by concentrated erosion at high tide level
Wave cut platform defitnion
Gently sloping rocky surface at cliff base
Wave cut platform formation
Left behind as the cliff retreats due to repeated collapse from erosion at the notch
Cave definition
A hollow in a cliff face
Cave formation
Erosion of lines of weaknesses like joints or faults often through hydraulic action and abrasion
Arch definition
Natural bridge like feature through a headland
Arch formation
Two caves on opposite sides of a headland in rode through and join
Stack definition
Isolated pillar of rock near the coast
Stack formation
Formed when top of an arch collapses due to gravity and erosion
Stump definition
Short remnant of a former stack
Stump formation
Formed as the stack is further eroded by waves and eventually collapses leaving
