1a- coastal systems

Question 1

processes in coastal system

Answer 1

erosion
transportation
deposition
weathering

Question 2

outputs from a coastal system

Answer 2

beaches
sand dunes
bars
bays

Question 3

flows of energy, examples

Answer 3

kinetic- waves and wind- brings sand onto beaches

gravitational- cliff collapse, LSD, destructive waves, mass movement

solar- provides energy for waves, dries sand for aeolian processes

Question 4

flows of sediment, examples

Answer 4

LSD
rivers
aeolian flows- sediment from beach moves to sand dunes
ocean currents - provide sediment form off shore

Question 5

what are sediment sells

Answer 5

closed systems- sediment can move between stores within the cell but only the finer sediment can move out of the cell

Question 6

what are sinks and sub-sinks

Answer 6

sinks- sediment is outputted away from wave action
sub-sinks- sediment will be eroded and re-enter the cells system
