Sedimentary rock is formed by silt and mud accumulating and being compressed into stone mostly by time and it's own weight. A few years of heavy rains would likely leave dirtier and darker deposits. Any violent change in the area ( earthquakes, volcanoes, etc. ) might completely change the nature and colour of the deposits on a short term or permanent basis. Biologics ( anything from bacteria to dinosaurs ) might have a period of unrestrained growth, affecting the type and shades of the layers.

What are the layers of rock made of?
Layers or strata in sedimentary rock are composed of deposited smaller rock particles and possibly organic matter.
How would you know the difference between igneous and sedimentary and metamorphic rock?
Sedimentary rocks tend to have layers. Igneous rocks tend to have crystals. If you don't see layers or crystals, the rock might be metamorphic.
What clues or characteristics do you look for i n order to identify sedimentary rocks?
== == Sedimentary rocks may exhibit strata, or layering. Sandstones will have visible sand grains. Limestones will fizz when placed in vinegar. Fossils usually only appear in sedimentary rocks. A rock made of an assortment of other rocks is usually sedimentary.
Are all rocks sedimentary rocks?
No. Actually, some rock is metamorphic, or Igneous. See, there is a rock cycle and rocks go in different stages(never the same way every single time!) . The rocks go through weathering. erosion etc.
Why can you see layers in foliated rocks but not in nonfoliated rocks?
Because layers from foliated rocks came from the same direction and nonfoliated rocks came from several directions

Talk about the patterns you can find in sedimentary rocks. Where do you see these patterns?
Sedimentary rock is formed when many rocks are broken into small pieces by erosion, after a long time the small rocks fuse together and become a rock with many different layers.

What makes up a sedimentary rock and what characteristics does it show?
Sedimentary rocks are simply the result of erosion, deposition, and cementation of different types of rock and there particles. They almost ALWAYS have layers that you can clearly see, because of being pushed together. Sometimes they may even have fossils in them.
How are Sedimentary rocks and Igneous rocks different?
Igneous rocks are formed from the cooling of molten lava or magma. Sedimentary rocks are formed by the deposition and compaction of sediment grains or by their chemical precipitation in water. For more information please see the related link.

Is sand stone a sedimentary a metamorphic or a igneous rock?
sandstone is a sedimentary rock because of the layers or lines you can see on it

Because layers from foliated rocks came from the same direction and nonfoliated rocks came from several directions
How can you tell sedimentary rocks from others?
== == The age of a sedimentary rock formation can be estimated by comparing it to radiometrically dated rock formations that contain the same fossil organisms. Geologic time categories have been identified according to the radiometric dating of fossils and the fact that they appear only in certain time periods. Therefore, if you look at a rock formation and find a trilobite fossil that has been identified by previous dating techniques as Cambrian, you can be fairly certain that the formation you are looking at is also Cambrian.
What is an intrusive rock is?
Sedimentary rocks are not intrusive. Igneous rocks are though. See the link below.
Where would you likely see sedimentary rocks?
under depths of water
