How sedimentary rocks are formed long answer?
Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.
What is the life cycle of a sedimentary rock?
Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification.
How are sedimentary rocks formed easy?
Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area.
How long does it take for an igneous rock to become metamorphic?
It can take hundreds of thousands to millions of years for igneous rock to become a metamorphic one.
How long does it take for sedimentary rocks to form?
The formation of sedimentary rocks can take anywhere from thousands of years to millions of years. Depending on the type of sedimentary rock, there… See full answer below. Our experts can answer your tough homework and study questions.
How big is a layer of sedimentary rock?
A layer of a sedimentary rock is 2 m thick. How many years did it take for this layer to form if an average of 4 mm of sediment accumulated per year? | Socratic A layer of a sedimentary rock is 2 m thick. How many years did it take for this layer to form if an average of 4 mm of sediment accumulated per year?
How are clastic sedimentary rocks like coal formed?
Clastic sedimentary rocks, like sandstone, form from clasts, or pieces of other rock. Organic sedimentary rocks, like coal, form from hard, biological materials like plants, shells, and bones that are compressed into rock.
How are igneous rocks transformed into sedimentary rocks?
These igneous rocks are usually not eroded to form sedimentary rocks but remain in the oceanic plate until it is subducted some tens or hundreds of millions of years later. In the subduction process, the igneous rocks are transformed to metamorphic rocks directly without being sedimentary rocks. How this 19-year-old earns an extra $3600 per week.
