4 marine transport processes
4 marine transport processes
Traction, saltation, suspension, solution
Traction process
Traction process
Rolling/pushing large sediment along seabed (high energy)
Saltation process
Saltation process
Bouncing/jumping of stones along seabed
Suspension process
Suspension process
Fine particles carried within moving water
Solution transport
Solution transport
Dissolved minerals transported invisibly in water
Longshore drift pattern
Longshore drift pattern
Zigzag movement along coast (swash up, backwash down)
When marine deposition occurs
When marine deposition occurs
When waves have low energy or abundant sediment supply
Aeolian processes
Aeolian processes
Wind entrainment, transport & deposition of sediment
Sub-aerial weathering
Sub-aerial weathering
Breaks down rocks in situ, weakening them
Carbonation weathering
Carbonation weathering
CO2 in rainwater creates carbonic acid, dissolves rock
