Uks evolving physical landscape Flashcards
What forms in concordant coaslines(parallel)
Bays and headlands
What are the three types of weathering
Biological, chemical and freeze thaw
What forms in discordant coastlines (perpendicular)
Coves
Name the four types of erosion
Hydraulic action, abrasion, attrition, corrosion
What erosion types are used in bays and headlands
Hydraulic action and attrition
What erosion types are used in coves
Hydraulic action and abrasion
Name 3 characteristics of a destructive wave
High energy, so tall. Strong backwash, plunging waves
Name 3 characteristics of constructive waves
More swash, low waves and energy, gentle waves
What rock type is needed for a wave cut platform
Hard rock (igneous and metamorphic)
What rock type is needed for cliff slumping
Soft rock (sedimentary)
Name the four processes to form a stump
Cave, arch, stack, stump
Name the two cliff erosion types
Cliff collapse and cliff slump
What is the longshored drift diagram
Prevailing wind comes at the coastline at a 5* angle, awash moves material up and back wash carrries it back until it runs out of energy
Name the two depositional features
A spit and a bar
Describe the formation of a spit
Due to longshore drift, material is deposited at the end of the headland, growing until the wind changes direction and it curves, forming a spit
