Geo-thermal force is needed in forming the sedimentary rocks. The fragments of igneous rocks by erosion are carried by water currents and deposited in the basin for millions of years. The upheaval in the earth strata bring these deposits deep. The pressure of earth mass and its heat converts these deposits in to sedimentary rocks. The red sand stone is the best example of sedimentary rock formation.

Why sedimentary rocks could not have been the first rocks on earth?
water is needed, and long periods of deposit of sediment at the bottom, to form the sedimentary rocks. A hot, molton earth could not have created such rocks.
What rocks are formed when sediments are compressed compacted and cemented togerther?
Sedimentary rocks.
What rocks are formed from broken rocks?
Clastic sedimentary rocks and Cataclasites (a form of metamorphic rock) are formed from broken rocks.
What class of sedimentary rocks is made of fragments of rock minerals and shells?
== == Clastic sedimentary rocks.
What percentage of rocks on earth are sedimentary?
Sedimentary rocks are the most common types of rocks that cover the earths surface because they are layered rocks. Approximately 65% of the rocks are sedimentary.
What is the or-gin of sedimentary rocks?
weathering of preexisting rocks form clastic sedimentary rocks, Oversaturated water basins form chemical sedimentary rocks after the water evaporates and dead sea organisms settle at the bottom forming biochemical sedimentary rocks.
What are the 5 major processes involved in forming sedimentary rocks?
Sedimentary rock formation begins with igneous, metamorphic, or other sedimentary rocks. When these rocks are exposed at the earth's surface they begin the long slow but relentless process of becoming sedimentary rock.
Forms as pieces of loose material get pressed or cemented together?
Sedimentary rocks form as pieces of loose material get pressed or cemented together. The process of forming sedimentary rocks is lithification.
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
Why sedimentary rocks could not have been the first rocks on earth?
water is needed, and long periods of deposit of sediment at the bottom, to form the sedimentary rocks. A hot, molton earth could not have created such rocks.
Are sedimentary rocks classified tofoliated sedimentary rocks?
Metamorphic rocks are classified by foliation or lack there of, not sedimentary rocks. They are classified into Clastic Sedimentary, and Chemical Sedimentary.
What force causes sedimentary rocks to be transformed into metamorphic rocks?
Pressure and heat from being buried under mountains.
Are sedimentary rocks being formed right now?
Yes, sedimentary rocks are being formed right now. Sediment is continually being deposited by erosion and transported by wind, water, and ice. Over time, these sediments are compacted and cemented together to form new layers of sedimentary rock.
What are forming fossils?
Fossils are formed in sedimentary rocks, which has multiple layers to show the level of soil back then.
Are sedimentary rocks formed from fragments of other rocks chemical sedimentary rocks?
No. The rocks you describe are clastic or detrital sedimentary rocks.
What has the author Sam Boggs written?
Sam Boggs has written: 'Petrology of sedimentary rocks' -- subject(s): Sedimentary Rocks 'Petrology of sedimentary rocks' -- subject(s): Rocks, Sedimentary, Sedimentary Rocks
Are there any fossils in sedimentary rocks?
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.
