The major processes in the formation of clastic sedimentary rocks include weathering, erosion, transportation, deposition, and lithification. Weathering breaks down rocks into smaller particles. Erosion and transportation move these particles to new locations. Deposition occurs when particles settle, and lithification compacts and cements them into solid rock.

FAQs & Answers

  1. What is weathering in sedimentary rock formation? Weathering is the breakdown of rocks into smaller particles through physical, chemical, or biological processes, which is the first step in forming clastic sedimentary rocks.
  2. How does erosion differ from transportation in sedimentary processes? Erosion involves the removal of rock particles from their source area, while transportation is the movement of these particles to new locations by agents like water, wind, or ice.
  3. What role does lithification play in sedimentary rocks? Lithification is the process where deposited sediments are compacted and cemented together to form solid sedimentary rock.
