== = Earth Structure and Volcanoes; Ice and how it changes the scenery = = = == Textbook Reference: Revise KS3 Geography Study Guide:pages 24 - 32 - the role of Ice is not covered in the textbook. But this more than covers what we will be talking about: http://www.bbc.co.uk/schools/gcsebitesize/geography/glaciation/ ==

Introduction
This half term we are looking at the Changing Earth. First of all we will look at what the structure of the Earth is like, and how it is due to this structure that movements take place, some of which give rise to volcanoes. We will look at what a volcano is like when it erupts and what can be done to help you through it as well as possible. The next section looks at ways in which the Earth’s surface can be changed and in particular, how this has happened in the past due to movement of Ice (glaciation), the ice sheets advanced and retreated during the Ice Ages. We will then look at the scenery that the Ice Ages left us with and impact it has on how humans have adapted to it.

This the mountain evidence:
The Appalachian Mountains of North America, some mountains in Newfoundland, Northern Ireland, Scotland and Norway are all the same - they were created at the same time, they are made of the same minerals - so how come?

===This is how come - can you see?===
