The 5 clastic rocks are conglomerate, breccia, sandstone, siltstone, and shale. Conglomerate consists of rounded gravel-sized particles. Breccia contains angular fragments. Sandstone is primarily composed of sand-sized particles. Siltstone has finer particles than sandstone but coarser than clay. Shale comprises clay-sized particles and is known for its fine-grained texture.

FAQs & Answers

  1. What is a clastic rock? Clastic rocks are formed from the accumulation of fragments derived from existing rocks, minerals, or organic materials.
  2. How are clastic rocks classified? Clastic rocks are classified based on the size of their grains, ranging from coarse conglomerate to fine shale.
  3. What are the characteristics of sandstone? Sandstone is primarily composed of sand-sized particles, known for its durability and is commonly found in sedimentary rock formations.
