The Work of the Sea
Tremendous amounts of energy are needed to erode and transport all the tonnes of rock which are removed from cliffs each year. The energy ultimately is provided by the Sun, via the convection currents (= winds) that the Sun generates in our atmosphere. Energy is transferred from the wind to the waves, and from one part of the ocean to another.
- waves transfer energy;
the water particles stay in the same average position - breakers (or breaking waves) transfer the water itself, causing erosion and transport.
