What is sedimentary rock in simple words?
Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth’s surface. Sedimentary rocks often have distinctive layering or bedding.

How are sediment formed for kids?
Some is formed when rocks of any kind are worn away by rain, wind, and other elements. Through a process called erosion tiny fragments of the original rock, along with dissolved minerals, are carried away to another site. There they may combine with other materials, such as mud. This settled matter is called sediment.
What are sediments short answer?
Sediment is solid material that is moved and deposited in a new location. Sediment can consist of rocks and minerals, as well as the remains of plants and animals.

Why are sedimentary rocks important?
Sedimentary rocks contain important information about the history of the Earth. They contain fossils, the preserved remains of ancient plants and animals. Coal is considered a type of sedimentary rock. The composition of sediments provides us with clues as to the original rock.
Where does sedimentary rock form?
Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.
How is a sedimentary rock formed?
Introduction. Sedimentary rocks are formed from deposits of pre-existing rocks or pieces of once-living organism that accumulate on the Earth’s surface. If sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.
How to make your own sedimentary rock?
STEP 1: Cut one of each color Starburst into fourths to act as sediments. STEP 2: Compact the pile of Starburst sediments together but do not form them, this will act as the Sedimentary Rock. STEP 3: Apply heat and pressure to the “Sedimentary Rock” with your hands or press into a ziplock/Starburst bag. How do you make sediment?
