Something that is static does not move or change

A flood is when there is too much water in a waterway, such as a river, and it overflows onto land that is normally dry

Energy is the power used to make things work, for example to provide heat or light or to operate machinery

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?

A {{}} is when there is too much water in a waterway, such as a river, and it overflows onto land that is normally dry.

Why are the cliffs at Happisburgh easy to erode?

{{}} engineering solutions are usually designed to act as a barrier between the sea and the land.

A {{}} fence-like framework built at a right angle to the shore. They help hold sand on the beach, instead of drifting away.

Which of these are soft engineering coastal defence strategies?

Waves approach the coast at an angle because of {{}}

sediment carried or transported by waves along the coastline

the process of Earth’s surface, e.g. rock or soil, being worn away

when sand, mud and rocks are dropped by the water carrying them

The backwash carries sediment back down the slope of the beach because of...

Waves approach the coast at an angle because of the direction of prevailing wind

The swash will carry the sediment towards the beach at an angle.

The backwash carries sediment back down the beach because of gravity.

The process repeats itself along the coast in a zigzag movement.

When water loses its energy, any sediment it is carrying is...

Which three of these coastal features was created by the process of deposition?

This lesson will soon be taken down.
