Sedimentary rock formation involves three main stages: weathering, transportation, and deposition. First, existing rocks break down into smaller particles. These particles are then transported by wind, water, or ice. Finally, they are deposited in layers, compacted, and cemented over time to form sedimentary rocks. This process can take millions of years and creates various rock types like sandstone or shale.
FAQs & Answers
- What are the main types of sedimentary rocks? The main types of sedimentary rocks include sandstone, shale, limestone, and conglomerate.
- How long does it take for sedimentary rocks to form? The formation of sedimentary rocks can take millions of years, depending on various environmental factors.
- What is the difference between igneous and sedimentary rocks? Igneous rocks form from cooled magma or lava, while sedimentary rocks form from compressed sediments.
