erosion happens everywhere, however if the rock is soft it wears away faster. Which statement is correct

• sand appears at the base of the bay and this is because of chemical weathering

• the headlands stick out and the bay is the inside part. This is because waves erode the softer rock

• bays are formed as hard rock is worn away at a faster rock than the surrounding softer rock

• headlands are areas of rock jutting out into the sea and because of that they are made of igneous rock
