WebSedimentary rocks are usually formed in water. Streams and rivers carry sediments in their current. When the current slows around a bend or the river empties into a lake, or ocean, or another river the sediments fall out because of gravity. The larger sediments fall out first and the lightest sediments fall out last.

WebIt can occur in many different types of sedimentary rock, from coarse sandstone to fine shales, mudstones or in evaporites . Because lamination is a small structure, it is easily destroyed by bioturbation (the activity of burrowing organisms) shortly after deposition. WebIt happens when water, oxygen, and other reactants chemically degrade the mineral components of bedrock and turn them into water-soluble ions which can then be transported by water. Higher temperatures accelerate chemical weathering rates.

WebLocation. 1st Floor. There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies.
