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 else can I help you with?
What are the layers of rock made of?
The layers of rock are primarily made up of minerals, which are naturally occurring inorganic substances with a specific chemical composition. These minerals can include quartz, feldspar, mica, and calcite, among others. Over time, these minerals accumulate and compact to form different types of rock, such as sedimentary, igneous, and metamorphic rocks.
How would you know the difference between igneous and sedimentary and metamorphic rock?
Igneous rocks form from cooling and solidification of magma or lava, sedimentary rocks form from the accumulation and cementation of sediment, and metamorphic rocks form from the alteration of existing rock through heat and pressure. By examining the texture, mineral composition, and sedimentary structures present in a rock sample, geologists can determine whether it is igneous, sedimentary, or 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 sedimentary rocks are porous?
they are often porous because of fossil imprints and pressure put on them at different spots
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.
Which rocks result from compacting and cementing particles together?
Sedimentary rocks are formed from the compaction and cementation of particles such as sand, silt, and clay. These particles are deposited in layers over time, and the pressure from the weight of the overlying material squeezes them together and binds them with minerals forming sedimentary rocks.
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
What is an intrusive rock is?
Sedimentary rocks are not intrusive. Igneous rocks are though. See the link below.
What type of rock if you are driving along a highway cut through walls of rocks made of layers?
If you are driving along a highway and see walls of rock made of layers, you are likely observing sedimentary rock. Sedimentary rocks are formed from the accumulation and compaction of mineral and organic particles over time, resulting in distinct layers or strata. Common examples include limestone, sandstone, and shale. These layered formations can often be seen in road cuts and cliffs.
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.
