Taos, New Mexico – Tasa Graphic Arts, Inc. is pleased to announce the release of Earth’s Rocks and the Rock Cycle, a new educational Earth Science app for iPad. 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:
* Hundreds of photos and animations by Dennis Tasa, with additional photos by Michael Collier and Ed Tarbuck;
