“The Rock Cycle”

This interactive resource explores the concept of the rock cycle, identifying relationships between the three types of rocks (sedimentary, igneous, and metamorphic) and demonstrating the processes involved. Utilize visual aids, including videos, animations, and diagrams, to enhance your understanding of this fundamental geological concept.

Presentation Transcript

  1. “The Rock Cycle” • Mr. Rellinger • Earth Science • Geology

  2. Introduction: Objectives • Graphically present the concept of the rock cycle. • Identify relationships between the three general types of rocks. • Demonstrate processes of the rock cycle.

  3. Navigation Directions • Focus on the relationships between the key points and the visual aids presented. • Use the following buttons to view various visual aids. Video Clip Animation Diagram

  4. Sources of the Three Types of Rocks Sedimentary Rocks: • Sediments or fragments of other rocks • Once dissolved inorganic (non-living) material 3. Hardened organic (once-living) material.

  5. Sources of the Three Types of Rocks Igneous Rocks: • Magma below earth’s surface • Lava on earth’s surface. Metamorphic Rocks: 1. All other rocks! They just “change.”

  6. The Diagram of the Rock Cycle Diagram

  7. Processes of Forming Rocks • Igneous: • Magma cooling below earth’s surface. • Intrusive • Lava cooling on earth’s surface. • Extrusive Animation

  8. Processes of Forming Rocks • Sedimentary: • (Clastic) Other rocks are erodedinto sediments, which, are compacted and cemented together. • (Chemical) Water evaporates leaving behind inorganic (non-living) materials that are compacted and cemented. • (Organic) Once living materials are compacted and cemented.
