What else can I help you with?
Why are fossil found in sedimentary rocks and not in igneous rocks?
== ==
Why shouldn't you look for fossils in igneous rocks?
Well, Igneous Rocks are formed from Magma and the bones of an animal or a plant wouldn't have the time to become a fossil
Do sedimentary rocks contain fossil?
yes fossils are found in sedimentary rocks but not in igneous and metamorphic rocks. hope this helps
Why aren't you likely to find a fossil in metamorphic or igneous rocks?
the fossils would be turned into another rock if it was in a metamorphic rock or igneous rocks. it requires a blanket of sediment
Fossils found in younger rocks?
The youngest rocks would be igneous, those created by cooling magma. Impossible to find a fossil there.
What aren't you likely to find a fossil I metamorphic rock or igneous rock?
The fossils will be crushed under the pressures required to create metamorphic rocks and they will melt in the heat required to make igneous rocks.
When molten rocks cools what rocks form?
igneous rocks
What are igneous rocks that form over the surface?
Rhyolititcen rocks.
What do you call rocks that have been formed from the hot molten material within the earth's crust that has cooled and hardened?
Igneous rocks are formed by the solidification of molten materials.
Are igneous rocks made up of igneous rocks?
Sedimentary rock can be made up partially of igneous clasts, but igneous rock is igneous rock.
How does determining the ages of igneous rocks help to date fossils?
Determining the ages of igneous rocks helps to establish the age of the rock layer in which fossils are found. By dating the igneous rocks above and below the fossil-containing layer, scientists can narrow down the possible age range of the fossils found within that layer. This helps to provide a more accurate estimate of the fossil's age.
Are volcanic rocks igneous rocks?
Yes. Volcanic rocks are extrusive igneous rocks.
