Superplume Concept Applies To Tharsis Area On Mars

This online article, published by the now defunct Daily University Science News (the article is still available in their archives), reports on the proposal of Victor Baker and Shigenori Maruyama, ...

Isostasy

This website provides animations, static diagrams, and photos are depicting the isostatic adjustments associated with the emplacement and removal of ice sheets. The website addresses the question: ...

Geochemistry of the Solid Earth I: The Mantle and Core

This site is a chapter from a book on geochemistry by Dr. W. M. White that is used in a geochemistry course at Cornell University. The 39-page PDF document discusses the composition and evolution of ...

Ultra-High-Pressure Experimentalist Who Studies the Deep Earth

This article profiles the work of Elise Knittle, whose research specialty is mineral physics. The essay gives an overview of the core, mantle, and crust of the Earth, including what we know about ...

Geol 202: The Earth's Interior

This beginning geophysics course is designed for geology majors. It provides a relatively rigorous and homework-intensive overview of the structure and evolution of the Earth and terrestrial planets, ...

The tr660 Program

The tr660 program models the mineralogy and physical properties for various chemical compositions in the Earth's mantle where a transition occurs in these properties at about 660 km depth. The ...

Earth's Interior

This web-based laboratory material explores the ways in which heat controls mantle dynamics, how seismic waves move through the mantle and may be used to investigate its properties, and how the ...

When North Goes South

This is a report of a computer numerical model of the electromagnetic, fluid dynamical processes of Earth's interior that reproduced key features of the magnetic field over more than 40,000 years of ...

Hot Spots and Mantle Plumes

This site describes mantle plumes, which are areas of hot, upwelling mantle. A hot spot develops above the plume. Magma generated by the hot spot rises through the rigid plates on the lithosphere and ...

Structure of the Earth

This site explains that seismologic studies of the Earth have revealed that it has several distinct layers. Each of these layers has its own properties and this information has helped to give ...

The Earth's Layers

This site contains information about the crust, lithosphere, mantle, convection currents, outer core and inner core of the Earth. The composition and thickness of each of the layers are described ...

Farallon Plate remnants

The Rockies are fifteen hundred kilometers, or one thousand miles, to the east. The cause must be the tectonic plate that built these mountains. Its name is Farallon. Farallon started off normally ...

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. ...

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 ...

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 ...
