The area where the ocean and the land meet and interact.
What is the shore?
100
A waste product that harms living things and damages an ecosystem.
What is pollution?
200
The process of moving sediment by wind, moving water or ice.
What is erosion?

When rocks are torn apart by physical force, with no chemical breakdown.
What is mechanical (or physical) weathering?
300
Large ocean wave usually caused by an underwater earthquake or a volcanic explosion.
