πŸ“š Quick Study Guide

  • 🌍 Sedimentary rocks are formed from sediments, which are small pieces of other rocks, minerals, and organic matter.
  • πŸ’§ Weathering and erosion break down existing rocks into sediments.
  • πŸ“¦ Transportation of sediments occurs via wind, water, ice, or gravity.
  • 🧱 Deposition is the process where sediments settle out of the transporting medium.
  • ⏳ Compaction occurs as layers of sediment are buried and squeezed together.
  • cementation is when dissolved minerals precipitate out of water and act like glue to bind the sediments together.
  • 🌱 Examples of sedimentary rocks include sandstone, limestone, shale, and conglomerate.
