Learner Express: Modules for Teaching and Learning
Earth's active processes of erosion and plate tectonics help explain why craters on the Earth are less visible than on its nearest neighbor, the Moon. View Video
A demonstration of viscosity and gas content of different types of magmas using chocolate syrup, mayonnaise, and seltzer water. View Video
Students in a playground act out an analogy for how temperature and pressure control the behavior of rocks in the Earth. View Video
By following sediments moved from the mountains to the sea, a mountain stream illustrates the process of erosion. View Video
Ocean floor features reveal the signature of tectonic plates, large, sometimes continent-sized rigid structures in the Earth's crust that can move independently of each other. View Video
The hot spot below Hawaii provides evidence for plate movement: as the Pacific Plate moves over the hot spot, it creates a string of islands. View Video
On average, soil only extends about one meter below the surface. Compared to the size of the Earth, soil is just a thin veneer on the surface. View Video
Part 1 of a three-part investigation into the sediments revealed at the ocean shore in Cape Cod, Massachusetts. View Video
Part 2 of a three-part investigation: ice flowing in the form of mountain glaciers is an important source of erosion in colder climates. View Video
Part 3 of a three-part investigation: over several episodes ending about 18,000 years ago, continental glaciers formed over much of North America. View Video
Extreme drill holes for research have only reached 14km below the surface—less than 0.2% of the distance to the other side. View Video
The various planets are thought to have formed from the solar nebula, the cloud of gas and dust left over from the Sun's formation. View Video
