One of the most important forces of change in the coastal system is:
global warming.
the power of waves.
holiday makers.
local community.
the fishing industry.
Waves are created by the:
wind blowing over the sea.
pull of the Moon over the Earth.
pull of the magnetic north pole.
position of the Sun in the sky.
gravity.
The distance a wave has travelled is called the:
Peak.
trough.
fetch.
catch.
carry.
When a wave breaks on a beach it is washed up the beach. This is called the:
swash.
swawl.
swish.
switch.
swoosh.
A wave rushing back down a beach towards the sea is called the:
backwash.
backswish.
backswitch.
backcrawl.
backswoosh.
A constructive wave occurs when:
the swish is stronger than the backswish.
the backswish is stronger than the swish.
the swoosh is stronger than the backswoosh.
the backwash is stronger than the swash.
the swash is stronger than the backwash.
Waves bring with them bits of rock and sand that grind down the cliffs. This is called:
abrasion.
corrosion.
infiltration.
Waves cause rocks and pebbles on the shore to smash into each other and break down. This is called:
hydraulic action.
attrition.
Deposition is likely to occur when:
waves enter an area of shallow water.
waves enter a sheltered area.
there is longshore drift.
where there are constructive waves.
all of the above.
