This site is designed to help students learn how mountains form, identify the components of mountain systems, and explore the transfer of matter and the role of energy during mountain building. It employs links to three other websites to lead students to information about the evolution of mountains, provide background information on the continent-continent collisions that resulted in the Himalayas, and explore geomorphology from space.
This web page is a module for Grades 5-8 on the topic of Earth’s atmosphere. It contains background information for teachers on atmospheric gases and their properties, explains how energy is transferred between the earth’s surface and the atmosphere, and discusses the role ocean currents play in transferring heat. Included are links to seven classroom activities and labs on radiation, conduction, convection, the water cycle, and more. NOTE: A few of the labs involve hot liquids and require close teacher supervision. See Related items on this page for additional resources by the same authors.
This diagram illustrates some of the most abundant stores of carbon and identifies some of the pathways in the carbon cycle along which carbon is transferred from one form to another. Long-term sinks of carbon are labelled in black; shorter-term fluxes are labelled in purple. Amounts are in billions of tons.
Respiration is a process in which electrons are transferred sequentially through a series of membrane-bound protein carriers, the electron transport chain. The figures and animations illustrate this.
