Name the landform visible in the photo.
tombolo
spit
arch
coral reef
Which of these is not a form of coastal erosion?
Attrition
Hydraulic action
Sub-aerial weathering
Solution
Which of these is NOT a condition that coral reefs need to form?
Water temperature of 27-29 degrees C
Shallow salty water
A good amount of sunlight
Clear water
Which is the correct definition of hydraulic action?
When particles of rock and pebbles are thrown up against the cliffs and break the rocks apart.
When waves smash against the cliffs, water is pushed into cracks and breaks rocks apart over time.
When waves smash against the cliffs, air becomes trapped in the cracks in the rock and causes the rock to break apart.
It's the sheer power of the waves hitting the cliffs.
