1.1 Mountains form, mountains wear down

2EH

In this paragraph we study how mountains form and get shaped

Which of the following learning targets you think would interest you most?

You know the difference between a young and an old mountain range

you understand how mountains can form out of oceanfloor or volcanism

you can recognise fossils and igneous rock from a photo

Magma

Volcanism

Subduction

Trench

oceanic plate

Continental plate

The formation of the Himalaya's

• Platetectonics
• After pangea broke up India and Asia became a convergent boundary
• Before they collided there was a massive ocean between the two continental plates
• Subduction formed after their collision which coused volcanism when the two continental plates crashed the himalays became very high

Oceanfloor or mountain?

• Layers of sandstone and other rocktypes got squashed and folded to form a mountain range
• Fossils came with the rock

So to answer the question of this slide, maybe they are both at the same time

Fossielen

Fossils 

Igneous rock

• Not all rock is formed at the bottom of the ocean
• Magma within the earth's mantel can be pushed towards the surface. The magma then cools, sollidifies and forms rock.
• A very common igneous rock is granite
• Magma -> igneous rock-> granite

Note!

What is this?

1. Fossil
2. Granite

Young and old mountain ranges

• Mountains also wear down / break apart
• Young mountain ranges are high, pointy and steep
• Old mountain ranges are lower, less steep and rounder

Note!

These are the Scottish highlands. Are they a young- or old mountain range?

1. young
2. old

What does granite look like?

1. Hot red magma
2. regularly spotted
3. irregularly spotted
4. Black or greyish colour

Get to work please 

• Put away your chromebook and get your workbooks out. 
• Write down the homework (check teachers whiteboard) into your diaries
• Start working on your assignments
