Short Term Processes Flashcards
Coasts can also be categorised by short-term factors
Waves - can be constructive or destructive
Tides - tidal range is the difference between high and low tide
Rivers
Storm events
Coasts can also be categorised by short-term factors:
Waves - can be constructive or destructive
Tides - tidal range is the difference between high and low tide
Rivers
Storm events
These create coastlines that can be:
Retreating or advancing which depends on whether erosion or deposition dominates
Dominated by land-based processes (primary coasts) or marine processes (secondary coasts)
Large or small tidal range
High or low-energy
High and low energy waves how do they contrast in there type of waves
high energy destructive
low energy constructive
High and low energy waves how do they contrast in there type of exposure
high energy- Exposed to strong winds and long fetches
low energy- Sheltered locations with short fetch
High and low energy waves how do they contrast in there type of rates of deposition and erosion
low energy - higher rate of deposition lower rate of erosion
high energy - Lower rate of deposition higher rate of erosion
High and low energy waves how do they contrast in the type of coast they form
high energy-Tend to be rocky coasts
low energy-Sandy beaches, salt marshes, estuarine and tidal mud flats
High and low energy waves how do they contrast in the type of relief
high energy waves -Steep cliffs - marine cliff profile
low energy waves-Gentle relief
High and low energy waves how do they contrast in the type of cliffs and sediment
high energy -Less steep cliffs - subaerial cliff profile
low energy- Sediment from land and sea
what kind of different landforms form at high energy and low energy wave locations
low energy-Beaches, spits, coastal plains
high energy-wave-cut platforms
