Not going into depth on any one topic, this Earth science presentation skims the crust. It touches on the materials that construct the crust and then moves into plate tectonics. This is a useful and colorful note-taking guide for your...

Young scholars discuss convection currents in the Earth's mantle, how they form, and how they move as well as the causes of earthquakes. Working in a group, they analyze a color coded World Earthquake Map and try to determine which...

Students examine the movement of plate tectonics. In this lesson on the spreading of the seafloor, students use maps and models to observe how the sea floor spreads.

In this earth and space science activity, students complete a crossword puzzle given 9 clues and a word bank on topics such as sea floor spreading, tectonic plates, faults, lava and the big bang theory.

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

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.

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...
