Sediments are solid materials that settle at the bottom of liquids, often found in rivers, lakes, and oceans. They can include particles like sand, silt, and clay, which are transported by water and deposited when the flow slows down. Over time, these sediments can build up and form layers, providing valuable information about the Earth's history. Liquids, such as water, play a crucial role in the movement and deposition of sediments. When water flows, it can carry sediments along with it, shaping landscapes and creating features like river deltas and beaches. Understanding the interaction between sediments and liquids is essential for fields like geology and environmental science.
