For our online topic this term we will be learning all about Mountains, Volcanoes and Earthquakes.
Lesson 1 - What is the earth made of?
In this lesson, we are going to be learning about the structure of the earth, what the earth is made of and where volcanoes and earthquakes occur and why.
This first lesson goes into a lot of detail about the Earth and its structure, so please don't worry if by the end of the lesson you have forgotten some of the information. The main points we would like you to remember are the names of the four main layers of the Earth.
