Inside Earth

Chapter One, Plate Tectonics

Chapter 1, Section 1, Earth's Interior

See what the seamounts and underwater canyons deeper than the Grand Canyon 150 miles off of Nantucket look like.

Plate tectonics is the continual slow movement of the tectonic plates, the outermost part of the earth. This motion is what causes earthquakes and volcanoes and has created most of the spectacular scenery around the world.

Chapter 1, Section 3

Drifting Continents

You will be Putting Together Pangaea

Here'a very good animation showing convection currents and tectonic plate boundaries.

Chapter 1, Section 2

Convection Currents and the Mantle

You and your lab partner will conduct a Convection Currents Lab and describe

the process observed in the purple water, like you have already for the 'Lava Lamp'.l

Chapter 1, Section 4, Sea-Floor Spreading

Here'a pretty good animation to show a sped-up version of the very slow process of the

formation of the Atlantic Ocean as Pangaea split up about 250 million years ago

Chapter 1, Section 5, The Theory of Plate Tectonics

You and your lab partner will conduct the Graham Cracker Plate Tectonics Lab to make models of the 5 kinds of Tectonic Plate Boundaries.

What's happening to East Africa?

Here's another excellent animation, of oceanic plate-ocean plate convergent boundary

The Þingvellir area is part of a fissure zone running through Iceland, being situated on the tectonic plate boundaries of the Mid-Atlantic Ridge. The faults and fissures of the area make evident the rifting of the earth's crust (Þingvellir National Park, Iceland, July).

This is the divergent plate boundary where the North American Plate is separating from the Eurasian Plate (Þingvellir National Park, Iceland, July).

What does a lava lamp have to do with convection currents?

An animation illustrating how convection cells in the asthenosphere drive sea floor spreading and move tectonic plates.

The plate boundary between oceanic and continental plates is also shown.

Plate TectonicsSee how mapping the location of volcanic eruptions and earthquakes can tell us where tectonic plate boundaries are. Dr. Elizabeth Cottrell explains how the plates interact and how volcanic eruptions actually cause earthquakes. Video from Smithsonian Institution.
