Weathering

The action of wind and water is called weathering:
* Erosion.
* Transport.
* Sedimentation.
We are going to do a model with plasticine and cardbord to represent the weathering.

 

The Geosphere

The geosphere is made up of three layers.
    - The crust is the Earth's outer layer. It is mad up of solid materials.
    - The mantle is the Earth's middle layer. It is extremly hot. In some parts, there is magma (red-hot    liquid rock).
    - The core is the Earth's inner layer. It is also extremly hot.

 

A volcano eruption

A volcano eruption.
    * Half fill a plastic bottle with sodium bicarbonate and place on a tray.

* Put sand around the bottle.

   * Mix vinegar and food colouring and pour it into the bottle.
