Earth’s Rocks and the Rock Cycle

By Tasa Graphic Arts, Inc.

This app is only available on the App Store for iOS devices.


Explore the three types of rock found on Earth and understand the geologic processes that create and transform them. View high resolution photos of rocks and explore the environments in which they are found. Use what you have learned about composition, texture, and color to identify rocks. Animations show the geologic processes in action: volcanic eruptions, flowing lava, weathering of rocks, streams transporting sediment, glaciers moving, caverns being formed by water, rocks being deformed by intense heat and pressure deep underground.

Learn how the rock cycle illustrates the geologic processes as they change one type of rock into another. Investigate how the hydrologic cycle interacts with the rock cycle. In the Rock Builder activity, use what you learned about the rock cycle to build new rocks from existing ones.

Features of this app include:

• photos and animations by Dennis Tasa, with additional photos by Michael Collier and Ed Tarbuck;
• pinch and zoom high resolution photos of rocks and their environments;
• an intuitive navigation style: swipe, drop-down menu, thumbnail gallery;

With descriptive text and optional narration, this app provides everything needed for Middle and High School science classes that study rocks, rock identification, or the rock cycle. It even covers the hydrologic cycle and the role water plays in the rock cycle. Appropriate for grades 5 to 12; contains scored quizzes as well as essay questions. Quiz results can be shared by email and AirDrop. The new version adds a Total Score for all quizzes that encourages independent study to obtain the highest possible score.
