Natural Hazards.

Lesson aims.

1. What is a natural hazard and how are they defined.

2. What examples of natural hazards are there.

3. To start looking at an example- Plate Tectonics.

Starter.

• Together we are going to watch a clip about the worlds natural hazards.

• In your books I would like you to note down all the hazards you recognise.

What is a natural hazard.

• 2 minutes- write down a sentence in your books that defines a natural hazard.

• We will then compare this to a text book definition to see how close you were.

A natural hazard is a natural event which is perceived by people as a threat to life and property. It may be generated from within the earth, upon the surface or happen within the atmosphere.

Pate Tectonics.

Cross section of the Earth

Continental drift

Why do the plates move?

Task.

• Using your base map of the world and page 74 of People Places and Themes add on the names of all the worlds plates and the direction in which they are moving.

Constructive plate boundary

Destructive plate boundary

Collision plate boundary

Conservative plate boundary

Homework.

• To find out the date and location of a recent earthquake and volcano and the impact these had on human activity.
