A definition of the process of weathering.

Learn how salt crystallizes and the weathering effect that this has on rocks and on structures.

This series of photos dramatically illustrates the process of mechanical weathering known as rock abrasion. Taken over a 100 year span, you can see the effects of rock abrasion on Jump-off Joe, a sea stack at Nye Beach in Oregon. The...

The Gravestone Project, part of the global citizen science program called EarthTrek, seeks volunteers to visit cemeteries around the world and collect scientific data on how marble gravestones are weathering.

In this investigation, students will use sand to build a mountain and then use a straw and watering can to simulate wind erosion and water erosion. Students will make observations and then propose ways to slow the erosion and/or speed...

This lesson is a demonstration in how geological layers form and erode using just a stack of towels. The author describes this lesson as GeoArt, which means one looks at geologic processes through both a scientific and an artistic lens.

While visiting three separate sites in or near the Minnesota River valley, students will question the deposition environment of rock types found and the creation of the valley itself. Students will discover find types of rock found far...

Slope failure is the downslope movement of rock debris and soil in response to gravitational stresses. Three major types of mass wasting are classified by the type of downslope movement. The types of movement, falls, slides, and flows...

Soils may be formed in place from rock or formed in weathered rock and minerals that have been transported from where the original rock occurred.

A collection of video lectures from a course introducing students to the basics of engineering geology. Webpage includes forty lectures from a professor at the National Programme on Technology Enhanced Learning. Lectures vary in length...

The most recent ice age peaked between 24,000 and 21,000 years ago, when vast ice sheets covered North America and northern Europe, and mountain ranges like Africa's Mt. Kilimanjaro and South America's Andes were encased in glaciers. At...

This digital textbook covers core earth science concepts and includes interactive features, real-world examples, videos, and study guides.

Resource for earth science review, with the following topics covered: composition of the Earth, mapping, rocks and minerals, weathering, and earthquakes. Includes a collection of online quizzes, review materials, old exams, and references.

In this lab, students investigate whether the rate of water falling (rain) affects the amount of erosion (soil movement). This experiment could lead to further questions: how does grass or rocks effect soil erosion, does erosion lead to...
