Why would you tend to find lots of fossils in sedimentary rocks Why not in other rock?
Most sedimentary rock is formed by layered sediment (sand,silt,clays, mud) packing on top on each other over millions of years which, under intense pressure, are compressed into rock. Dead animal corpses that existed in an oxygen deprived environment (swamps,bogs,seafloors) fail to entirely decompose before sediment completely buries them. They in turn are solidified by the same process and their bones go underneath a process where all the organic material is replaced (mineralization). The mineralized structures resemble the bone structure of the animal (a fossil!). This would not occur in metamorphic or igneous rock as the origin of these rock forms are too hot, too compressed, and too deep in the earths crust for mineralized animal remains to exist.
What else can I help you with?
In which type of rock are fossils least likely to occur?
Fossils would not likely be found in rock other than limestone, sandstone, and shale, or rock such as marble that has morphed from these sedimentary rocks. Fossils can basically be find in most Sedimentary rocks, but not in Igneous rocks because they are formed in volcanoes.
Why are fossils most likely to be found in sedimentary rock samples?
Most fossils are found in sedimentary rock, because igneous and metamorphic rock undergo great heat and pressure when forming, where as sedimentary rocks undergo much less pressure and heat to form, better preserving the fossil
Which bedrock would most likely to contain fossils?
sedimentary bedrock
How would you explain a horizontal sedimentary rock layer containing Cambrian fossils lying on top of a rock layer containing Ordovician fossils?
The Adirondack rocks have been both severely folded and sheared by ductile deformation and shattered by brittle.
Why do the lower levels of sedimentary rock on Earth show fossils of the simplest life forms?
The lower the level of a rock stratum, the older it is. Evolution is recorded in the sedimentary rock record, therefore, the simpler forms would show up in the oldest layers. The old life forms were usually very simple so the deeper down the sedimentary levels are, the older the fossils are their.
Would you find fossil in sedimentary rocks?
Yes, you can find fossils in sedimentary rocks.
What layer would old fossils be located?
Sedimentary rocks layers.
What might sedimentary rock contain that igneous rocks would not?
FOSSILS.
Would you be less like to find fossils in metamorphic rocks than in sedimentary rocks?
Yes.
In which type of rock are fossils least likely to occur?
Fossils would not likely be found in rock other than limestone, sandstone, and shale, or rock such as marble that has morphed from these sedimentary rocks. Fossils can basically be find in most Sedimentary rocks, but not in Igneous rocks because they are formed in volcanoes.
Which which mars rock contains fossils sedimentary igneous or metamorphic sedementary igneous or metamorphic.?
There is currently no confirmed evidence of fossils on Mars. Sedimentary rocks are usually associated with the formation and preservation of fossils on Earth, so if fossils were to be found on Mars, they would likely be in sedimentary rocks.
Why are fossils most likely to be found in sedimentary rock samples?
Most fossils are found in sedimentary rock, because igneous and metamorphic rock undergo great heat and pressure when forming, where as sedimentary rocks undergo much less pressure and heat to form, better preserving the fossil
ARE Fossils always found in igneous rocks?
No, fossils are typically found in sedimentary rocks rather than igneous rocks. Sedimentary rocks form from the accumulation and lithification of sediments, making them more likely to preserve fossils due to their layered nature. Igneous rocks, on the other hand, form from the cooling and solidification of molten rock and are less likely to contain fossils.
Does igneous sedimentary and metamorphic rocks contain fossils?
No. In general, there are no fossils in igneous or metamorphic rocks, because the high heat and pressure involved would destroy any fossils. Fossils are almost always found in sedimentary rock.
Why do rock fossils form in sedimentary rock and not in igneous rock-?
Fossils are formed in sedimentary rock because the rock is formed at temperatures that do not destroy the fossils like the igneous rocks would.
Where would you find a rock with fossils in it?
You can find rocks that are sedimentary rocks which are found in mountains, rivers and near the seashores.
What kind of rock do fossils form?
Sedimentary rock, its rarely found in metamorphic and never found in igneous rock because it would make the fossil of the animal worped and changed. It wouldn't be with the original form on metamorphic and igneous would destroy the whole fossil.
