Coastal Landforms and Processes
Year 7 Humanities
We learnt at the beach about dunes and parts of the beach. We measured the height of the sand and we saw the direction of the waves.
Hydraulic action is when waves smash into rocks eroding them
Attrition is when waves smash rocks on the shore into each other
Abrasion is when bits of rock grind down surfaces like sandpaper
Corrosion is when acids in sea water will dissolve some types of rock.
