Stream Deposition Patterns
This Flash animation reveals deposition patterns associated with a river flowing into a lake. The animation shows a cross-section of stream flow as it enters a lake, with decreasing velocity reducing the water's ability to carry sediments in suspension. The conditions create a predictable pattern of deposition with the largest sediments deposited near the shore and smaller sediments settling farther out where the water is calmer. The animation may be played, paused, forwarded, and rewound manually.
This Flash animation from Michigan Tech drapes a watershed boundary upon a mountainous landscape and then shows how, after rainfall, surface runoff is funneled into a hierarchical drainage net. The animation shows how the watershed's trunk stream leaves the confines of the basin to drain adjacent watersheds.
Animations of Glacial Processes
This site features four Flash animations of glacial processes. Topics include glacier basics, ice flow in a glacier, cross-section of an ice sheet, and crevasse formation. Each short animation includes captions and diagrams which define terminology and explain the processes depicted.
Seasonal Migration of Snow Cover on Mt. Ranier
This Flash animation shows the seasonal fluctuation of the snow line on Mount Rainier, Washington. A compilation of monthly images show the approximate amount of snow cover on the mountain for a full year and the image with the least amount of snow shows the position of the snow line. The animation can be paused and rewound to emphasize important points.
Observe Changes in the Channel of a Meandering River
This aerial photo of the Rio Puerco River in New Mexico shows the path of the river channel in four different years. Flash enabled slides superimpose meandering patterns from 1935, 1958, 1973, and 1990 to show how the river has changed course over time. Users can click to turn the river's path on or off for each year and examine the paths to see where straight sections of the river developed meanders or meandering sections were later straightened.
Oxbow Lake Formation
This animation shows the process of oxbow lake formation. Detailed captions and slides explain how differential flow velocities and the resulting patterns of deposition and erosion along river banks eventually lead to the development of an oxbow. Click play button to view each slide.
Resources for Earth Science and Geography Instruction
This website contains links to sites featuring maps, images and other topics related to an introductory earth science or physical geography class. Links are also available for environmental science, earth science/geography education, career opportunities, and more. The sites selected are based on image quality, ease with which lesson plans can be developed, organization, authenticity, scope, and format.
Climate Monitoring and Diagnostic Laboratory: Carbon Cycle Greenhouse Gases
The National Oceanic and Atmospheric Administration Climate Monitoring and Diagnostic Laboratory Carbon Cycle Greenhouse Gases group makes ongoing discrete measurements from land and sea surface sites and aircraft, and continuous measurements from baseline observatories and tall towers. These measurements document the spatial and temporal distributions of carbon-cycle gases and provide essential constraints to our understanding of the global carbon cycle. This website is an interactive atmospheric data visualization tool. This tool enables users to view data, obtain details about sampling locations, manipulate and compare data sets and create custom graphs. Data includes information on a variety of gases, and can be viewed as seasonal patterns, time series, or latitudinal distribution.
Climate TimeLine Information Tool
The Climate TimeLine (CTL) Information Tool summarizes climate history for time spans from 1 year to 100,000 years ago and beyond. The relation between human development, weather, and climate is explored. The CTL explains how past climate is measured, provides basic information on paleoclimatology, and explains the use of paleo proxies. There is a tutorial on drought and how to use the CTL to investigate that topic. There is also a climate glossary and links to climate and paleoclimate data.
The goal of the PALEOMAP Project is to illustrate the plate tectonic development of the ocean basins and continents, as well as the changing distribution of land and sea during the past 1100 million years. In the section on Earth history you can select any time period, read about that period, and see the plate distribution during that period. There is also a section on climate history where you can select a time period, see the climatic distribution of that period, and learn what evidence was used to reconstruct the paleoclimate. A collection of animations shows the plate distribution during different parts of Earth history. The site also has a section where you can print paleomaps that are formatted to be cut out and pasted on a 4 inch Styrofoam sphere to create your own paleoglobes.
