settekivimeid
Settekivimeid, also known as sedimentary rocks, are one of the three main rock types, alongside igneous and metamorphic rocks. They are formed from the accumulation and cementation of mineral or organic particles on the Earth's surface. This process, called lithification, typically occurs over vast stretches of time.
The origins of these particles, or sediments, are varied. They can be fragments of pre-existing rocks that
Settekivimeid are often characterized by distinct layers, or strata, which reflect changes in the depositional environment
