A mystery in the Alps

(High) in the mountains you can

find fossils (+sedimentary rock).

How were the Alps formed? part 1

Sedimentary rock

Magma

How were the Alps formed? part 2

Africa (with Italy!!) moved in northern direction to Europe

==> the bottom of the sea came under pressure

How were the Alps formed? part 3

Folded rock

The bottom of the see got folded by the pressure of the moving plates.

Igneous rock

In some places the igneous rock (=rock from magma) almost reached the surface.

How were the Alps formed?

Put the sentences in the correct order. Fill in your answer on the next slide like a code (e.g. 12345)

1. There is a sea between Italy and the rest of Europe.
2. The sedimentary rock is compressed and pushed upwards.
3. Rivers end up in this sea and deposit sand and clay.
4. Sedimentary rock is formed slowly on the bottom of the sea.
5. Africa and Italy are moving North.
