Water in nature always contains minerals.
Sediments are deposited when wind or waterways slow down or when glaciers melt.
Layers of sediment form over many years, leading to compaction.
Sedimentary rock forms when sediment is buried and compressed, and salts from fluids cement the grains together.
Strata can be used to create a relative timeline and provide clues to the environment when the sediments were deposited.
