Rocks are the Earth's ancient storytellers, shaped by millions of years of geological processes. Here's a glimpse into their fascinating world:
🪨 What Are Rocks?
Rocks are naturally occurring solid aggregates of minerals. They form the foundation of the Earth's crust and come in three main types:
- Igneous (fire-born): Formed from cooled magma or lava
- Sedimentary (sediment-strewn): Built from compacted layers of sand, silt, and organic material
- Metamorphic (transformed): Created when existing rocks undergo heat and pressure changes

🌊 The Rock Cycle
Nature continuously reshapes rocks through the rock cycle:
- Weathering breaks rocks into smaller pieces
- Erosion transports these fragments
- Deposition layers them into sedimentary rocks
- Melting forms igneous rocks
- Metamorphism transforms rocks under extreme conditions
This cycle highlights Earth's dynamic balance, where mountains wear down and new landforms rise. 🌍
