Is it true or false that metamorphic rock is rock that forms when sediments are compacted and cemented together?
False. Metamorphic rock forms when existing rock is subjected to high temperature and pressure, causing it to change its mineral composition and structure without melting. Sedimentary rock forms from sediments being compacted and cemented together.
Process by which sediments are stuck together to form sedimentary rock?
The process by which sediments are stuck together to form sedimentary rock is called lithification. Lithification involves the compaction and cementation of sediment particles to create a solid rock through pressure and mineral precipitation. This process typically occurs over long periods of time under the Earth's surface.
Is conglomerate a clastic rock?
No, conglomerate is a sedimentary rock composed of rounded rock fragments cemented together. Clastic rocks are composed of individual grains or fragments of minerals or rocks that have been compacted and cemented together.
Where are the oldest layers of a sandstone rock located?
Sandstone is a sedimentary rock. Sedimentary rocks form from sediments that deposited by the wind and water. Over the time those sediments will get pressed and cemented together. It can take millions of years for sediments to become a rock. So the oldest layers of a sandstone are on a bottom.
What is the cycle of the sedimmentary rock to show how it's formed?
Sedimentary rocks are formed through the process of weathering, erosion, transportation, deposition, compaction, and cementation. Weathering and erosion break down existing rocks into sediments, which are then transported by wind, water, or ice before settling and being compacted under pressure. Over time, these compacted sediments are cemented together to form solid sedimentary rocks.
What kind of rock is formed from sediments being cemented together?
sedimentary rock
What are sedimentary rocks ad how are they formed?
Rocks made from sediments being compacted & cemented together.
Is it true or false that metamorphic rock is rock that forms when sediments are compacted and cemented together?
False. Metamorphic rock forms when existing rock is subjected to high temperature and pressure, causing it to change its mineral composition and structure without melting. Sedimentary rock forms from sediments being compacted and cemented together.
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.
Process by which sediments are stuck together to form sedimentary rock?

Lithification involves the compaction and cementation of sediment particles to create a solid rock through pressure and mineral precipitation. This process typically occurs over long periods of time under the Earth's surface.
What types of rocks would be associated with fossils?
Fossils are usually found in sedimentary rock. Processes hardened them into sedimentary rock, as pressure squeezed the water out and the grains were cemented together. Often plants and animals were trapped, being buried in the sediments. As the sediments hardened into sedimentary rock, the dead things hardened into fossils.The following are examples of sedimentary rocks:ShaleSandstoneLimestoneSiltstoneMudstoneChalkClaystoneItacolumiteBituminous coalOoliteOil shaleArkoseArgilliteConglomerateDiatomiteRock saltRock GypsumCoquinaAsphalt rockAlabasterGreywacke or wackeTravertineBanded ironGritstoneJaspilliteOrthoquartziteRadiolariteLigniteMarlDolostoneFlintChertIronstoneBreccia
How are each of the major types of rocks formed?
Igneous rocks are formed from magma or lava cooling and hardening. Sedimentary rocks are formed from sediments being compressed and cemented together. Metamorphic rocks are rocks that are changed by extreme heat and pressure.
Is conglomerate a clastic rock?
No, conglomerate is a sedimentary rock composed of rounded rock fragments cemented together. Clastic rocks are composed of individual grains or fragments of minerals or rocks that have been compacted and cemented together.
How is erosion part of the formation of sedimentary rock?
Sedimentary rocks are, by definition, rocks that are composed of layers of sediments. Sediments are particles of rock and other materials. So if you have a rock that's being weathered and eroded, it's getting broken down and carried by water and wind. Eventually the rock will be broken down so much that what's left will be sediments. These sediments will pile on top of each other, compacting under the pressure from higher layers and creating a sedimentary rock.
What is the uniformitarian explanation for how most sedimentary rocks formed?
According to uniformitarians, sediments are laid down slowly over millions of years. Eventually, conditions change and the sediments harden to form rocks. The conditions during which the sediments were laid down determine the type of sediment, which in turn determines the kind of rock formed.
