Cliffs and wave-cut platforms Soft rock erodes quickly and forms gentle sloping cliffs, whereas hard rock is more resistant and forms steep cliffs.
What is the difference between hard rock and soft rock?

Which type of rock is more resistant to erosion?
Hard rock such as chalk is more resistant to the processes of erosion. When the softer rock is eroded inwards, the hard rock sticks out into the sea, forming a headland. Erosional features such as wave-cut platforms and cliffs can be found on headlands, since they are more open to the waves.
Which rocks erode faster sand or clay?
The bands of soft rock, such as sand and clay, erode more quickly than those of more resistant rock, such as chalk. This leaves a section of land jutting out into the sea called a headland. The areas where the soft rock has eroded away, next to the headland, are called bays.
Is sandstone a hard rock?
