Grade 8 Rock Types Quiz with Multiple Choice Questions and Answers

📚 Quick Study Guide

• 🌋 Igneous Rocks: Formed from the cooling and solidification of magma or lava. Examples: Granite, Basalt.
• sedimentary Rocks: Formed from the accumulation and cementation of sediments. Examples: Sandstone, Limestone.
• ⛰️ Metamorphic Rocks: Formed when existing rocks are changed by heat, pressure, or chemical processes. Examples: Marble, Slate.
• 🔍 Rock Cycle: The continuous process by which rocks are created, changed from one type to another, destroyed, and then formed again.
• 🧪 Key Processes: Weathering, erosion, compaction, cementation, melting, cooling, and metamorphism.
