Is aragonite more likely to be found in younger or older fossils?
Aragonite is more likely to be found in younger fossils. This is because aragonite is a less stable form of calcium carbonate compared to calcite, which tends to recrystallize into calcite over time in older fossils.
Why are the oldest fossils sometimes not on the bottom layers of rocks?
Older fossils may not always be found at the bottom layers of rocks due to geological processes like folding, faulting, or erosion, which can disrupt the original order. In these cases, older fossils may be found at higher layers while younger fossils are found in lower layers.
Are fossils found in upper layers of sedimentary rocks are older than fossils found in no one there is a sedimentary rocks?
Fossils found in the upper layers of sedimentary rocks are generally younger than those found in lower layers, due to the principle of superposition, which states that in undisturbed layers, older sediments are deposited first and are buried by younger sediments. If there are no sedimentary rocks present, it is impossible to compare their ages directly. Thus, the age of the fossils can vary significantly depending on their specific geological context.
How do you determine the relative age relationship of faults to the rocks they cut?
Relatively, they are younger than the rock they cut through.
How do fossils in rock layers help scientists identify the age of rocks?
Fossils in rock layers can be used for relative dating, where older fossils are found in lower layers and younger fossils in higher layers. By comparing the fossils in different layers to known fossil sequences, scientists can estimate the age of the rocks. Fossils provide a timeline of life on Earth and can help determine the relative ages of rock layers.
Younger fossils and not older fossils are more like?
this is an incoherent question that cannot possibly be answered
Why can carbon-14 only be used to measure young geologic material?
It can only be used for younger fossils and such because carbon-14 has a relatively short half-life of around 2400 years.
What are the difference between reworked fossils and leaked fossils?
From the law of faunal succession,older beds are characterized by fossils of older age and the younger beds are characterized by younger age fossils.But in some exceptional condition the younger fossils are reported in the older formation and those are termed as leaked fossils. whereas,Fossils of older age occur in younger rock are known as reworked fossils.They are derived from the older rocks by reworking ad recycling of sediments.
Where are older fossils mostly found under or above younger fossils?
If the rocks containing the fossils have been involved in a mountain building episode they would be folded and if some of the folds were laid in a recumbent position and later eroded you would have older above younger rocks. Of course, it would be easy to find out if this was the case because of the various sedimentary structures in each separate layer of rock.
Why would fossils found at the top of a canyon probably be younger than those found at the bottom of the canyon?
The fossils found at the top of a canyon will probably be younger than those at the of the bottom of the canyon because the fossils at the bottom of the canyon would have been there earlier when the so called "canyon" was once a flat land, so as time went by, the flat land began growing and getting taller and finally became a canyon so the fossils at the top of the canyon WOULD be younger than those at the bottom because the bottom fossils were there before the top of the canton even existed.
Is aragonite more likely to be found in younger or older fossils?
Aragonite is more likely to be found in younger fossils. This is because aragonite is a less stable form of calcium carbonate compared to calcite, which tends to recrystallize into calcite over time in older fossils.
What evidence is there that earth has had a succession of flora and fauna?
Fossils!Fossils are the 'remains' of plants and animals (including humans) which lived in the past. Millions of fossils have been found all over the world. They show clearly that different species of plants and animals lived in the past and that they changed over long periods of time. Older fossils are simpler than younger fossils and we can work out the sequence of evolution from these fossils.For example the oldest vertebrate (backboned) fossils are fish. Younger than these are the first amphibians. Then reptiles appear as fossils, followed by birds and mammals.See:http://animals.about.com/od/evolution/a/vertebrateevolu.htmhttp://txtwriter.com/Backgrounders/Evolution/EVpage01.htmlhttp://evolution.berkeley.edu/evosite/lines/Ifossil_ev.shtmlhttp://www.fossilmuseum.net/

Where can you find the oldest fossils in sedimentary rock layers?
The oldest fossils are typically found in the deepest sedimentary rock layers, which are located at the bottom of a rock formation. This principle is known as the law of superposition in geology, where older rock layers are found beneath younger ones.
Fossils found in younger rocks?
The youngest rocks would be igneous, those created by cooling magma. Impossible to find a fossil there.
What is a cradles?
1. cradle snatcher A person who prefers relatively younger sexual partners or courtship partners. Someone who dates a person considerably younger than themselves.
