This ambitious course in Earth Science is the first of its kind. DJ Lake inspires wonder, explaining challenging scientific concepts clearly and easily.

Starting billions of years ago at the beginning of time, we bring you right to the present day. The veil is lifted on why the Earth works as it does, how we know what we know about our planet, and how all this affects your daily experience of the world.

This course is an introduction to Earth Science topics through the history of geology and chemistry. It is aimed at giving the student knowledge of why and how we know what we know in Earth Science. If you are looking for a course that will teach you identification of common rocks & minerals, you might find another course more appropriate because the focus here is big-picture ideas. 

We'll answer the fundamental questions...

• How are mountains made?
• Why do oceans exist?
• What is a crystal?
• How old is the Earth?
• and many more…
