Mantle Convection Moving Plates

This demonstration models the manner in which the convection currents in the mantle of the Earth cause movement of the plates. Convection currents in the mantle were thought, for many years, to be ...

Solid Mantle in Full Flow: The DIY Potty Putty Simulation

This demonstration illustrates the properties of the mantle of the Earth, using potty putty mixed with a solution of borax and simple glue. When left on the desk the potty putty will sink and spread. ...

The Earth's Internal Heat Energy and Interior Structure

This resource identifies the sources of the Earth's internal heat energy as extraterrestrial impacts, gravitational contraction of the Earth's interior, and the radioactive decay of unstable ...

Isostasy

This resource provides information on isostasy and the effects of glaciation on the Earth's lithosphere. The descriptions and scientific illustrations demonstrate how glaciers and the growth of ...

Thermal Convection and Viscosity of a Fluid

In this activity, students construct a model that will allow them to experiment with thermal convection, illustrating how thermal energy can generate a flowing motion in a fluid. The thermal ...

Explorations in Earth Science: Three-D Earth Structure Model

In this activity, students use modeling clay or baker's clay to construct a 3-D model of the interior of the Earth to help visualize the main spherical layers or regions (the inner core, outer core, ...

Explorations in Earth Science: Journey to the Center of the Earth

This virtual journey to the center of the Earth introduces the traveler to the structure, material properties and conditions within the Earth's interior. The size and scale of the Earth and of its ...

Earth Structure and Changes (title provided or enhanced by cataloger)

In the first of these two modeling activities, students make a model and label the layers of the interior of the Earth including the inner and outer cores, the mantle and the crust. In the second ...

Journey to the Center of the Earth

This 1 hour 36 minute radio broadcast discusses the first direct evidence that the inner core of the Earth is spinning faster than its crust. Guest host Richard Harris talks with researchers about ...

Deep Mantle Plumes Help Explain Hawaii's Origins

This radio broadcast discusses a theory that says the Hawaiian Islands formed as a result of deep mantle plumes. The theory of plate tectonics does not explain their origin, since they are in the ...

Scientist Proposes Alternative to Deep Mantle Plumes

This radio broadcast continues the discussion from the previous show ('Deep Mantle Plumes Help Explain Hawaii's Origins') over whether the Hawaiian Islands were created by deep mantle plumes. Don ...

Magnetic Reversals: Fact and Fiction

In this activity students learn about Earth's magnetic reversals by reading two fiction stories and a scientific summary of past reversals, including graphical information. This will help students ...

Earth's Inconstant Magnetic Field

This article discusses our planet's magnetic field, which is in a constant state of change. The location of the North Pole has been moving north at an average speed of 10 km per year, lately ...

New Type of Deeper, Longer Quake Discovered

This radio broadcast reports on the discovery of a new kind of earthquake that is much deeper and longer lasting than other kinds of quakes. These long, super-deep tremors originate at a depth of ...

Rapid Earthquake Viewer

The Rapid Earthquake Viewer (REV) provides access to earthquake data from seismograph recording stations around the world. The Earthquake View lets users select an earthquake and see data at various ...

Hotspots: Mantle Thermal Plumes

This article discusses the idea of 'hot spot' volcanoes, those not associated with plate tectonic boundaries, but rather with relatively stationary sources of heat energy (thermal plumes) in the ...

An Introduction to Geomagnetism

This tutorial introduces students to geomagnetism, the Earth's magnetic field, and its changes through time and space. Topics include the properties of Earth's magnetic field, how it makes a compass ...

N.E. Pacific and W. North America Plate History, 38 Ma to Present.

This page presents an animation by Tanya Atwater of the evolution of the western margin of the North American plate from 38 Ma to present. Motions are shown with respect to a stationary North America.

Layers of the Earth

This activity is designed to familiarize students with the layers of the Earth and their approximate thicknesses. Students will cut and paste circles of paper to model the crust, mantle, outer core, ...
