Coastal Landscapes And Change

Question 1

What is the littoral zone and what is it divided into

Answer 1

The wider coastal zone, including coastal land areas and shallow parts of the sea just offshore

Coast-land adjacent to sea
Back shore-area above high tide level
Foreshore-wave processes occur between high and low tide marks
Nearshore-shallow water area close to land
Offshore-open sea

Question 2

What are examples of inputs, processes and outputs in the coastal system

Answer 2

Inputs-marine, atmosphere, land, people

Processes-weathering, ,mass movement, erosion, depostion

Output-erosional, depositional landforms

Question 3

What are examples of inputs, processes and outputs in the coastal system

Answer 3

Inputs-marine, atmosphere, land, people

Processes-weathering, ,mass movement, erosion, depostion

Output-erosional, depositional landforms

Question 4

Where do coasts get their sediment supply from

Answer 4

Rivers

Cliff Erosion

Offshore sources

Wind

Longshore drift

Question 5

Difference between high and low energy waves

Answer 5

High energy

Destructive waves, rocky coasts, high erosion, due to strong wind and long fetch

Low energy

Constructive waves, sandy, depositional beach, little wind and short fetch

Question 6

What causes a submerging or emerging coastline

Answer 6

Where coast is rising relative to sea level-emergent

Coast is flooded by rising sea level- submerged
