Learners observe and measure a model of slow down slope movement.  In this graphing lesson students collect, record, and organize data that apply to models.   

The resource explores the Earth. There are tutorials on plate tectonics, plates and boundaries, and the Earth's structure. There is also an introduction and an interactive activity to test the students on skills taught.

Discover Alfred Wegner's ideas relating to continental drift and seafloor spreading which are both evidence to the concept of plate tectonics.

[Free Registration/Login may be required to access all resource tools.] Discusses what a tectonic plate is and how scientists can recognize its edges, how the plates move by convection in the mantle, the three types of plate boundaries...

Flip over this interactive OLogy card to find fast facts, questions and answers, and similar bite-size pieces of information about plate tectonics.

In this interactive tutorial you will learn about the theory of continental drift and why it was ultimately rejected. Then learn about the theory of plate tectonics and the evidence to support it. Lastly discover the types of boundaries...

A simulation that demonstrates divergent plate boundaries and seafloor spreading. A focus is on evidence of the Earth's normal and reversed polarity over geologic time in the rock record.

The resource explores the Earth. There are tutorials on plate tectonics, plates and boundaries, and the Earth's structure. There is also an introduction and an interactive activity to test the students on skills taught.

The plate tectonics and other features of the Earth's lithosphere are explained and illustrated. Has links to definitions of the magnetosphere, atmosphere, and hydrosphere.

In this interactive tutorial you will learn how pressure creates stress and strain on rocks. Learn how different types of strain are produced by different plate tectonic settings, and explore the different types of mountain ranges and...

One of the first lines of evidence suggesting the existence of plate tectonics was the discovery of very similar fossils in rock masses separated by vast distances and by ocean expanses. It suggested that those land areas had in the past...

[Free Registration/Login may be required to access all resource tools.] The history of plate tectonics past and future.

In this interactive tutorial you will learn about the types, forms, and hazards of volcanoes. The types of landform common to volcanic activity is discussed. Then, the landforms commonly resulting from intrusive igneous activity are...

A quick, introductory lesson about how earthquakes happen, and what impact these natural events have on life.

Learn about the supercontinent known as Pangaea that broke apart into the continents that we know today. Answer questions when you finish reading.

This site contains information about we have learned about the San Andreas Fault since 1906.

Site from the Southern Kings Consolidated School about mountains. Learn what mountains are and how they form.

Did you know the continents on Earth are in constant motion? Our knowledge of this is thanks to both Alfred Wegener and Harry Hess. This article discusses the work of these two scientists.

Take this online quiz and test your knowledge of geological history, and the formation of our atmosphere, water, crust, oxygen, tectonic plates, Moon, and the rest of the Earth.
