Geography

This unit links to 'Global trade: How do we get our stuff?' by understanding how coastal development and jobs are linked to trade and travel. 

This unit develops the idea of land use in 'Farms and factories: where does our food come from?' and revisits briefly 'Settlements: Where do people live and why?' in considering coastal settlements, and also builds on the idea of sustainable travel explored in 'Sustainable world: Does it matter how we live?'.

Coasts: what happens where the land meets the sea?

{{}} is material that is moved by water or air and settles in another place.

{{}} is when sand, mud and rocks are dropped by the river.

Which process creates coastal features such as cliffs, caves and arches?

{{}} is the process of moving material from one place to another. 

Calm seas can only transport {{}} particles of sediment. 

{{}} are formed by the wind blowing over the surface of the sea.

Put the coastal features in the order they would form. 

Harder rocks erode more {{}} than softer rocks.

Coastlines made of hard rock will create:
