In this video segment from Nature, learn the geological process by which the next Hawaiian island will be formed. [1:12]

This lesson introduces and explores the Pacific Ring of Fire. It is 1 of 3 in the series titled "Geology: Pacific Ring of Fire."

This lesson introduces the plate tectonics of the world and discusses their effects on the earth. It is 2 of 3 in the series titled "Geology: Plate Tectonics."

A science teacher demonstrates a number of simple models that teachers can use, or have students make, when teaching about plate tectonics and earthquakes. [5:38]

This video provides a brief explanation of the inner workings of plate tectonics. [2:36]

Material to begin an exploration of the Earth's interior. An hour-long video is accompanied by learning goals, an outline and overview, details on igneous rock, seismic waves, and the Earth's layers, and ideas for teaching this unit in...

This video focuses on earthquake preparedness in Arizona. It includes what to do and what not to do during an earthquake. The basic message is "Stop, drop, and hold on."

Discusses the idea of Pangaea and some of the evidence behind its existence.

Discusses the formation of the Hawaiian Islands by the stationary hot spot under the Pacific plate.

Get an introduction to plate tectonics with this video lecture. Video discusses the core, crust, and mantle as well as the difference between the crust and lithosphere [7:59]

Discover plate tectonics and the compositional and mechanical layers of the earth including: Crust, mantle, core, lithosphere, asthenosphere, mesosphere, outer core, inner core

The 1964 Great Alaska Earthquake occurred on Good Friday, March 27th. Liquefaction in and around Anchorage tore the land apart and was the second largest quake ever recorded by seismometers. This animation shows the underlying causes and...

A short video illustrates how a megathrust earthquake can create a tsunami. Check out the additional resources provided below the video. [1:16]

See how converging oceanic and continental tectonic plates react to one another.

Find the connection between earthquakes and volcanoes. This clip will illustrate volcanic earthquakes. [1:44]

Video introduces mantle convection which is the slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior of the Earth to the surface. It goes on to explain how the Earth's...

Explains in more detail the different layers that make up the structure of the Earth. [9:33]

A detailed discussion of plate tectonics, and the evidence of plate movement that can be found to support plate tectonic theories. [13:18]

A video lecture exploring how the plates in Earth's mantle move due to convection. [6:03]

A video lecture exploring plate tectonics. Learn about the core layers and what causes the layers to spread apart causing a divergent plate boundary. Video also gives examples of divergent boundaries found around the globe. [11:57]

Explore the geological features of convergent plate boundaries in this video. Learn that as the plates come together a volcano, a earthquake or more could occur. [6:03]

Nice, visual animation showing what happens under the Earth's surface at a divergent boundary.

Find out how scientists know that basin-range extension is ongoing. [1:00]

Watch this video to learn how every volcanic eruption and earthquakes are a reminder that Earth is very much alive and in motion. [4:27]
