Concord Consortium
Concord Consortium: Exploring Earth's Seismicity
This sequence is an introduction to plate tectonics using evidence from topographical maps, earthquake location and depth, and volcano location using the Seismic Explorer model to investigate patterns of earthquake data and to infer the...
Purdue University
Purdue University: Thermal Convection
Students build a model representing the properties of Earth's mantle, illustrating how thermal energy creates movement in a fluid.
Georgia State University
Georgia State University: Hyper Physics: Heat Convection
Using understandable words and exceptional graphics, this page describes the transfer of energy by means of the convection process. Contains several links to related topics.
Exploratorium
Exploratorium: Science Snacks: Pie Pan Convection
In this experiment, students observe what happens when a pan of soapy, colored water is heated. They will see that convection currents cause the fluid to rise and sink in a localized convection cell.
University of Calgary
University of Calgary: Energy Education: Geothermal Gradient
A good, concise explanation of the geothermal gradient and how and why the Earth's temperature gets hotter and hotter with increasing depth. Includes two diagrams showing this and the heat transfer mechanisms that are taking place.
