As a wave breaks air is compressed into cracks in the rock.
The rock is loosened so that the fragments are washed off.
Pebbles are repeatedly picked up from the sea bed and

The fragments are constantly rolled back and forth by the waves, so
that sharp edges are knocked off.

(i)
Plucking – loose rocks on the valley floor become frozen into
the glacier and are ‘plucked’ away as the glacier moves on.
Abrasion – the plucked rocks frozen into the bottom of the
glacier act like the teeth of a file and scratch and scrape the
rocks that the ice moves over.

60.
The meltwater rolls the pebbles so that sharp edges are smoothed
off. On the other hand, moraine is not rolled – it is frozen in the
ice, so fragments remain angular.
61.
They are sorted by the running water. When the current is strong
large fragments are laid down. When the current is weak only
small fragments are deposited.

34.
It has been more strongly metamorphosed.
35.
They are usually destroyed by the heat or the pressure.
