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:

  1. Weathering breaks rocks into smaller pieces
  2. Erosion transports these fragments
  3. Deposition layers them into sedimentary rocks
  4. Melting forms igneous rocks
  5. Metamorphism transforms rocks under extreme conditions

This cycle highlights Earth's dynamic balance, where mountains wear down and new landforms rise. 🌍
