Rocks and Minerals

This guide explores the three main types of rocks: sedimentary, igneous, and metamorphic. Sedimentary rocks form in layers from mud, sand, and fragments of other rocks underwater, often containing fossils of ancient life. Igneous rocks are created when magma cools, with some even floating due to trapped air bubbles. Metamorphic rocks result from intense pressure and heat transforming existing rocks into new forms. Discover the fascinating processes and features that define each rock type and their significance in the Earth's geology.

  1. Rocks and Minerals By Colin

  2. Sedimentary Rocks • Sedimentary rocks are formed when mud, sand, and bits of rock pile up in layers under water. • Sedimentary rocks often contain fossils, pieces of animals or plants that lived long ago. • Sedimentary rock has been formed in layers often found near water sources with fossils from decayers.

  3. Igneous Rocks • Igneous rocks are formed when magma cools. • Igneous rocks have been here since the earth was born. • Some igneous rocks float because the large number of trapped air bubbles.

  4. Metamorphic rocks are new rocks formed by pressure and heat. Metamorphic rocks are like rock makeovers. Metamorphic rocks are made out of other rocks. Metamorphic Rocks
