Q

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:

A

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

Q

High and low energy waves how do they contrast in there type of rates of deposition and erosion

A

low energy - higher rate of deposition lower rate of erosion

high energy - Lower rate of deposition higher rate of erosion
