Year+7+Unit+4

== = Earth Structure and rocks; Rivers and how they change the landscape = Year 7 Lesson 18

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. Then we look at why there are different kinds of rocks and some of the uses we put them to, and the problems this can cause. The next section looks at ways in which the Earth’s surface can be changed and in particular, how rivers affect the landscape. For this I am hoping that most of you can arrange to go and explore a river sometime between week 18 and the end of half term!

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?
