Sedimentary Rocks- Formation and Types

Turn your class discussion of rock formation from ho-hum to holy hornfels! Junior geologists gain experience in identifying rock types and rock origins, with an emphasis in hypothesizing the environment needed to form certain rocks. The...

Fascinating photos of sedimentary rocks and formations supply a brief overview for your geology class. By viewing these slides, learners discover that sedimentary rocks are made of tiny bits of rock, dirt, or shell that have settled,...

Students investigate the stripes in sedimentary rocks, using a structure at Petra, Jordan, as an example, and then do a hands-on activity using mixed nuts to illustrate the layering of sedimentary rocks.

A thorough description of different types of sedimentary rocks, their formation, their mineral structure, and where they are found in the world is present in this geology video. Some excellent images, tables, and graphs are used to...

Photographs of magnificent metamorphic rock formations make up the bulk of this brief slide show. Along with the upbeat background music, slow-moving slides, and informational captions of the slide show, you will also find key...

Dynamic music pumps up viewers as they learn about intrusive and extrusive igneous rocks. Presentation slides include a graphic depiction of magma below Earth's surface , photographs of lava exploding and flowing, and close-ups of...

Students review the three types of rocks and the rock cycle. They participate in an experiment in which they discover the lithification process of sedimentary rocks. They record and share their observations.

This video, meant for older students, clearly explains how each of the three types of rocks on the earth's surface are formed. I learned that 75% of the earth's land area is made up of sedimentary rocks! Interesting details about the...

A simple activity goes a long way in demonstrating the property of porosity to your rock hounds. They will mass a specimen of dry sandstone and then soak it in a pre-measured amount of water. After seven minutes, they once again measure...

Math rocks! Cavern design teams determine the rankings of rock types based upon desirability points. The points are connected to the properties of the rocks and their usefulness in building a cavern.
