Real-World Examples of the Rock Cycle Happening in Nature

📚 Quick Study Guide

• 🔥 Igneous Rocks: Form from cooled magma or lava. Examples: Granite (intrusive), Basalt (extrusive).
• sedimentary Rocks: Form from compacted and cemented sediments. Examples: Sandstone, Limestone.
• ⛰️ Metamorphic Rocks: Form when existing rocks are changed by heat, pressure, or chemical processes. Examples: Marble (from limestone), Slate (from shale).
• 🔄 The Rock Cycle: A continuous process where rocks change from one type to another. Processes include weathering, erosion, compaction, cementation, melting, and metamorphism.
• ⏳ Time Scale: The rock cycle operates over vast geological timescales, often millions of years.
• 🌡️ Factors Influencing the Cycle: Temperature, pressure, and the presence of fluids play crucial roles in the rock cycle.
• 🌊 Erosion & Weathering: Breakdown of rocks into smaller pieces, transported by wind, water, or ice.
