1.1.3 - landforms and landscape systems, theie distinctive features and distribution Flashcards
1
Q
what is the morphology of a coastline due to?
A
erosion, weathering, deposition, lithology
2
Q
what 3 things occurs at high-energy, erosive, rocky coasts?
A
mass movement - rockfalls from unstable cliffs, often during winter
weathering - biological, chemical, mechanical - loosen rocks
wave erosion - keeps coastline rocky and debris free, due to hydraulic action often forms landscapes
- high energy and long fetch
3
Q
what is occuring at low-energy, depositional, sandy coasts? example?
A
- production of sediment is more than the rate of removal of sediment
- often backed by sand dunes, with
- shallow shoreline gradient
constructive waves - mass movement - littoral drift
4
Q
what occurs at a tide-dominated?
A
beaches, spits
5
Q
what is an example of a rocky coastline?
A
the gower
6
Q
what is an example of a depositional coatsline?
A
the netherlands
7
Q
what landforms occur at wave-dominated stretches of coastline?
A
headlands, cliffs, wave-cut platforms
