LANDFORMS

Choose the right land formation to match the description. "Low waves that bring sand and shingle to build up a beach."

STACK FORMATION. First, there is a [blank_start]crack[blank_end] opened up by hydraulic action. It eventually gets bigger and forms a [blank_start]cave[blank_end] by hydraulic action and [blank_start]abrasion[blank_end]. This becomes larger. Then it breaks through the headland forming a natural [blank_start]arch[blank_end]. This then gets eroded and collapses leaving a tall rock [blank_start]stack[blank_end]. This is further eroded forming a [blank_start]stump[blank_end].

Long shore drift occurs in areas where prevailing winds approach at a perpendicular angle.

Tick the three man made features that are meant to prevent erosion.

What is the distance that the wind blows over the sea called?

The stack goes through the process of erosion in the final stage of stack formation.

What is the proper geographical definition of a lagoon?

Headlands are formed when the sea attacks a section of coast with alternating bands of [blank_start]hard[blank_end] and [blank_start]soft[blank_end] rock.

Coastlines where the geology alternates between bands of hard rock and soft rock are called...?

When a wave breaks, water is washed up the beach - this is called the [blank_start]swash[blank_end]. Then the water runs back down the beach - this is called the [blank_start]backwash[blank_end]. With a constructive wave, the swash is [blank_start]stronger[blank_end] than the backwash. With a destructive wave, the [blank_start]backwash[blank_end] is stronger than the [blank_start]swash[blank_end].

Tick the 2 boxes that are advantages of groynes.

On a purely sand beach, the coarse sand will be at the top and the finest particles will be by the sea.

The water behind a spit is a .......... environment. Choose the correct answer.

The movement of eroded material up and down, and along the coast is called [blank_start]transportation[blank_end]. When the sea loses energy, it drops the sand, rock particles and pebbles that it has been carrying and deposits them. This is called [blank_start]deposition[blank_end].

Abrasion is when waves cause the rocks to crash against each other, breaking them down into smaller and rounder pieces.
