What you will learn

Learn about the history and workings of planet Earth.

Learn about global phenomena, rocks, crystals, plate tectonics, geologic time, and how rocks form.

Learn how geology influences everything from the shape of the landscape to natural events (often called disasters.)


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…

The presentations lack visual content, the presenters style is awkward and stilted. This is supposed to be audio visual. Poor audio, very little visual.

I have a huge passion for the natural sciences, namely earth sciences and physics. I haven't had any opportunities to learn about these sorts of things in my education thusfar so I am definitely looking forward to this course!

Though I was expecting a course on 'rocks and minerals', I am exceedingly happy to have found an exploring over time of the BIG picture in geology. From the original question 'How old is the Earth', the course follows the convoluted logic of human discoveries that have resulted in the theory of plate tectonics. I am very pleased and very greatful for this learning opportunity.

So Far, I am really enjoying this class! The teacher is very easy to follow and has made it very interesting.

I am learning so much. At first I thought you were speaking so slow but then realized how much I was retaining. I am 64 years old and it's been a long time since I took any classes. I am learning so much.

This is interesting for someone has not taken a Geology-related course in a few years. I am attempting to get into Grad School under Geology. I am curious if you could grant some of advice for someone trying to enter a Master's Program (How to look, personal statements) or your experiences during the program?

First of all his voice is just magic. His pace is slow but I think this is a great thing. It is easy to follow along. Great so far!

He takes it at a nice steady pace. Not so fast and is a wonderful start to learn Geology for first timers.

Excellent and fascinating in terms of the big picture, concepts and the history of geological investigation, but I'd like to have learned more about identifying rocks I see when out walking or at the sea shore, and the various eras of geology one hears about e.g. devonian, pre-cambrian etc.

Really enjoying this. I love his presentation. It’s well paced and acknowledges the overwhelming nature of the information.

it was really a very successful education. I learned a lot as a basic knowledge about geography. Thank you.

Yes, it was a good match for me because I have a limited understanding about when the earth started or what is the age of the earth.

It was a nice course. Simple and entertained. The teacher could have talked about some branches of geology or related fields of research, such as geophysics, geochemistry, seismology, stratigraphy, sedimentology, economic geology, ore deposits, paleontology, and so on.

I have learned more than I ever thought I would! I would recommend this course to anyone interested in geology; I really like the teacher and his teaching methods. The topics presented are described with ease, and I can tell he is knowledgable on them. Furthermore, like any good scientist, he admits when he has gaps in knowledge. Also, the lectures are well spaced out and allow me to study at my own pace. If you want to learn geology, this is the place to go. What makes this course even better is that it is completely free! I never thought I could learn so much from a free online course! (My favorite quote was "Geological phenomena don't happen in a vacum.")!

definitely a good match for me! I have always been fascinated by geology but I started my family very young and did not have a chance to pursue it. So happy to be able to now!
