What else can I help you with?
Are you more likely to see sedimentary rocks on the surface or deep in earth's crust?
Of all the rock on Earth's surface, 75% is sedimentary rock. But, sedimentary rock is only about 5% of the whole crust. Unlike igneous rock, which forms underground, sedimentary rock forms from materials at Earth's surface. Which this means that sedimentary rocks are more likely to be seen on the surface. Hope this helps :)
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.
Is volcanic rock older than sedimentary rock?
Not necessarily. There are volcanic rocks that date back to the precambrian time, much older than most sedimentary rocks around today. At the same time, as there is still continuous volcanic activity on earth, some volcanic rocks may be only minutes old, making them the youngest rocks on earth.
What 3 kinds of sedimentary rocks make up coquina?
Coquina is a sedimentary rock made up of shells, shell fragments, and skeletons of small marine creatures.
Do you ever think we will run out of sedimentary rocks. Why or why not.?
We can only run out of them if we ship them off the planet. They are being formed as we speak, under the surface of the land and at the bottom of the ocean.
What is the name of six sedimentary rocks?
clastic,organic,chemical those are the only ones i know.
Fossils are found only in .?
Sedimentary rocks
What Sedimentary rocks are the only rocks that can potentially contain?
fossils
What are the 4 types of sedimentary rocks?
There are only 3 types of sedimentary rocks and they are...Clastic RocksChemical RocksOrganic rocks
Do all sedimentary rocks bubble in acid?
No. Only sedimentary rocks containing carbonate minerals will bubble with acid.
Why can only sedimentary rocks contain in tact fossils?
Sedimentary rocks form three horizontal layers: strata, singular and stratum. The organisms that fall into the sedimentary rocks, will then be fossilized in each layer.
Do igneous rocks usually contain fossils?
Igneous rocks are formed from cooling and solidifying of molten rock, so they usually do not contain fossils. This is because fossils are typically found in sedimentary rocks, which form from the accumulation of sediment and organic materials, preserving the remains of plants and animals.
Why are sedimentary rocks the only ones that contain fossils?
Sedimentary rocks form from the accumulation and cementation of sediments, which can entomb and preserve the remains of plants and animals as fossils. Igneous and metamorphic rocks form from molten material or intense heat and pressure, which would destroy any fossils present.
Are fossils found in sedimentary and metamorphic rocks?
no, fossils are found only in sedimentary rock.
Is coal an extrusive or an intrusive?
Coal is neither extrusive nor intrusive. Coal is a sedimentary rock that forms from the accumulation and compaction of plant material over millions of years. It is typically found near the Earth's surface in sedimentary basins and is not formed through volcanic or igneous processes like extrusive or intrusive rocks.
Sedimentary rocks formed when they undergo?
Sedimentary rocks are formed when pre-existing rocks, minerals, or organic material undergo weathering, erosion, transportation, and deposition. These sediments then undergo compaction and cementation to form solid rock layers.
Are metamorphic rocks only formed by igneous rocks?
No. Metamorphic rocks can also from front sedimentary rocks and from other metamorphic rocks.
