Start-up exercise

Answer the following question in your notebook:

How do you think mountains are formed?

Write down as much information as you can come up with. 

Today:

1. Inside the earth

2. Endogenic versus exogenic forces

3. Homework assignments.

Inside the earth

The crust: The layer on which we all live. 

Mantle: First layer under the crust - magma flows.

Outer Core: Supports the Mantle

Inner Core: Boiling hot middle of the earth

Slabs/Plates

The earth's crust is divided in slabs/plates. These 'float'on the fluid mantle. 

This causes the earth's crust to change --> tektonic movement

Three different types of movement

Convergent

Divergent

Endogenic versus Exogenic

Mountainranges are formed through endogenic forces. 

But, exogenic forces also affect mountainranges. 

Endogenic

Exogenic

Endogenic forces help to form young mountainranges

Exogenic forces break down young mountainranges.

Mountainranges are affected by weathering and erosion

Weathering = breaking down of rock

Erosion = transportation of weathered material

Process of weathering/erosion

Process:

1. Weathering makes rock break down high in the mountains.

2. Weathered material falls down.

3. It is transported to other places by glaciers, rivers, wind and sea.

4. During this transportation process, the landscape is eroded.
