coastal landforms and sandspits

what are bays

• A bay is an inlet of the sea where the land curves inwards, usually with a beach.

• When the softer rock is eroded inwards, the hard rock sticks out into the sea, forming a bay

• A bay is a wide gently-sloping surface found at the foot of a cliff.

• A headland is an inlet of the sea where the land curves inwards, usually with a beach.

• A headland is a wide gently-sloping surface found at the foot of a cliff.

what are wave-cut platforms

• A wave-cut platform is a wide gently-sloping surface found at the foot of a cliff.

• Wave-cut platforms are shaped through erosion and weathering

• A wave-cut platform is an inlet of the sea where the land curves inwards, usually with a beach.

• When the softer rock is eroded inwards, the hard rock sticks out into the sea, forming a wave-cut platform.

what are cliffs

• Cliffs are shaped through erosion and weathering

• When the softer rock is eroded inwards, the hard rock sticks out into the sea, forming a cliff

• A cliff is a wide gently-sloping surface found at the foot of a cliff.

describe relation of sandspits and bays

• a sandpit shelters the bay from storm waves

• longshore drift moves sandy mud along the coast

• a spit may join up with an island

• if the lagoon is completely cut off, it becomes a bay

describe relationship between bays and lagoons

• if the bay is completely cut off, it becomes a lagoon

• a bay may join up with the lagoon

• the lagoon keeps growing until it joins the bay

• lagoon shelters bay from storm waves
