The Rock cycle is a process whereby all types of rock are formed then eroded and "recycled" through different depositional processes. Sedimentary rocks can provide evidence that the rock cycle exists by looking at it under a microscope. Sedimentary rocks are formed by the lithification of grains of different sizes shapes and compositions. By detemining the compositions of the grains within a sedimentary rock through a petrographic microscope or through a scanning electron microscope (SEM) then it can be seen that some grains are composed of minerals that are solely igneous in origin. Likewise, sedimentary rocks can be metamorphosed to form meta-sediments.
What else can I help you with?
What evidence does fossils found in sedimentary rocks provide?
It can provide evidence of the environment the area was in in the past. For example, if you found a fossil with tentacles, you could guarantee that it is a marine creature (as tentacles are useless on land). You can then go on to imply that the rock was also formed in a marine environment. An example is shale, which is formed in a tranquil marine environment. This gives evidence of the past environment and also climate. Coal is also a fossil. A coal seam is sure evidence of a warm climate and a deltaic/marshy landscape.
In which rock type are fossils usually founs?
Sedimentary, since the other two types involve extreme heat and/or metamorphism which could destroy any fossil evidence
Which type of rock is where fossils are found?
They are mostly found in Sedimentary Rocks
How did fossils provide evidence for contental drift?
Because, similar fossils could be found on different continents, in rocks of the same age.
What is the cementing material between the grains in a sedimentary rock?
The cementing material could be calcite, clay minerals, iron minerals, or quartz in a clastic sedimentary rock.

How fast can Bigfoot run?
As there is no credible evidence that such exists, figures on how fast it could run are unavailable.
Could people be werewolves?
Werewolves are mythical creatures and no scientific evidence has ever been found that one exists.

Can you provide an example of weak evidence in a criminal investigation?
Weak evidence in a criminal investigation could be a single unreliable witness testimony without any corroborating evidence, such as physical evidence or surveillance footage.
In which rock type are fossils usually founs?
Sedimentary, since the other two types involve extreme heat and/or metamorphism which could destroy any fossil evidence
Which type of rock is where fossils are found?
They are mostly found in Sedimentary Rocks
What does a sedimentary rock have?
it could have sand in it
How did fossils provide evidence for contental drift?
Because, similar fossils could be found on different continents, in rocks of the same age.
What do you call documents evidence at a crime scene?
They are typically referred to as "forensic evidence" or "crime scene evidence." These documents can include things like photographs, maps, diagrams, witness statements, and any other materials that could provide insight into a crime.
From the rock cycle describe the changes that a sedimentary rock could undergo?
A sedimentary rock could undergo further compaction and cementation to become a metamorphic rock due to increased heat and pressure. It could also melt and solidify into an igneous rock through volcanic activity. If exposed to erosion, it could break down into sediments and form new sedimentary rocks through deposition and lithification.
Which discovery could provide evidence against the theory of evolution?
A discovery that shows species appearing suddenly in the fossil record without any preceding ancestors would provide evidence against the theory of evolution. This would contradict the gradual changes in species predicted by evolution.
