It is true that the composition of a sedimentary rock depends upon the composition of the rocks and living things its sediments come from. Sedimentary rocks form through lithification.

What type of sedimentary rock is made out of dead living matters?
organic/biochemical sedimentary rocks are formed of once-living organisms
Why have sedimentary rocks been very important to scientists who study how living things have changed over the ages?
The vast majority of fossils are found in sedimentary rocks. Fossils are they key to understanding what living things used to be like.
What does sedimentary rock and fossils have in common?
Most organic matter(living plants,insects,animals etc,) gets fossilized by the layers of sediments and with heat and pressure in millions of years become fossils.This process of preservation is not possible in other types of rocks.
Chemical composition of non living things?
Basic Geology lists over 200 different types of non living minerals.
Why are fossils formed in sedimentary rocks but not in igneous rocks?
Because sedimentery rock is formed under the sea, sediment collects at the bottom of the ocean, and so does a few dead sea creatures, then t gets squashed by other sediment, igneous rock is formed by lava cooling, so there is no fossils in it.
When sediments of living things are pressed together you are left with what?
Sedimentary Rocks are formed when sediments and pressed and cemented together. It is also formed from minerals that are left after a solution is evaporated.
What kind of rock is made when rock minerals and remains of living things are made when these sediments are cemented together?
sedimentary rock
What are the steps that turn sediment into rock?
Sedimentary rocks are formed by the lithification (cementing, compacting, and hardening) of existing rock or the bones, shells, and pieces of formerly living things. Rocks are weathered and eroded into tiny particles which are then transported and deposited along with other pieces of rock called sediments. Sediments are cemented together and compacted and hardened over time by the weight and pressure of up to thousands of feet of additional sediments above them. Eventually, the sediments are lithified and become solid sedimentary rock. These sediments that come together are known as clastic sediments. Sediments usually sort themselves by the size of the particles during the deposition process so sedimentary rocks tend to contain similarly sized sedimentary particles. An alternative to clastic sediments are chemical sediments which are minerals in solution that harden. The most common chemical sedimentary rock is limestone, which is a biochemical product of calcium carbonate created by the parts of dead creatures. Approximately three-quarters of the earth's bedrock on the continents is sedimentary.
What is the composition of a sedimentary rock?
Small solid materials that come from pieces of rocks and living organisms
What are the remains of once-living orgainismsfound in sedimentary rocks?
All fossils are found in sedimentary rocks. Some sedimentary rocks are made of nothing but fossils such as chalk. A creature ( microscopic or larger) skeleton is deposited after death usually on the ocean floor. Sediments cover it, and over time turns into a fossil.
Why do rock fossils form in sedimentary rock and not igneous rock?
Sedimentary rock can be made from sediments cemented together, or formed in the shape of remains of living things. Igneous rock is made from cooled magma, inside or outside the crust.
How do Sedimentary rocks formed and what are they made of?
Sedimantary RocksThese rocks are formed from th ehot lavaJk jk i was bored i dont reall know what they mean and i real HATE STAaR
What is a rock and how it is form?
A sedimentary rock is formed from sediments, that is particles of preexisting rocks that have been broken down by weathering process and transported to new locations by water, ice or wind. The sediments accumulate over time as layers deposited parallel to the Earth's surface and, as they become buried by overlying deposits, they harden to form rock - sedimentary rock. During their deposition process, they may include burrows, shells or bones of living creatures and these become fossils as the sediments harden.

What are sedimentary rocks from living or once-living material called?
They are called organic sedimentary rock.
What type of rock is clastic and non-clastic?
Clastic sediments are sediments that have particles or pieces of rock (clasts) in them. The clasts can be of igneous, metamorphic or sedimentary rock. Non-clastic sediments are made up of dissolved minerals or organic matter.
How do chemical rocks form?
The key is the sediments. ... Biochemical sedimentary rocks are formed from organic processes that involve living organisms producing the sediments. These living organisms can be snails and clams whose discarded calcium carbonate shells can form limestone.
