Earth Quest provides comprehensive information about rocks, minerals, and the geophysical forces that shape our planet. Learn how Earth evolved over billions of years and how it continues to develop and change to this day! You'll see the Earth from a different perspective as you see each rock and mineral sample classified according to its structure and properties with in-depth information about each specimen. Students can create their own 3D volcano, set off an earthquake, and more. Photographs, audio, video and text all combine to provide a comprehensive geological reference source. Ages 9 and up.
