What else can I help you with?
What type of dating would be used to determine the age of rocks by using the fossil?
By using the geologic time scale. Certain organisms are only found during certain times and if a fossil of one of these organisms is found then you can determine the relative age of the fossil.
To compare the relative ages of fossils scientists sometimes use an easily recognized species called?
To compare the relative ages of fossils, scientists use an early recognized species called an index fossil. An index fossil must have existed for a short period time and must have covered a wide geographical range.
What is the value that tells you whether s fossil is younger or older?
Scientists use a method called Carbon Dating to find out the age of a fossil.
Why are index Fossil helpful for performing relative dating?
Because they give us the best estimate of how old all the other fossils are in that sedimentary layer.
Which fossil would most likely make the best index fossil?
A good index fossil is one of an organism that rapidly evolves and is widespread throughout a geologic time period or periods. This makes it useful in determining the age of the rock formation in which it is contained.
How does relative dating and absolute dating help scientists assemble a fossil record for an area?
Relative dating is the science determining the relative order of past events, without necessarily determining their absolute age Absolute dating is the process of determining an approximate computed age in archaeology and geology.
Could you tell the relative age of a fossil if layers of rock have been shifted by earthquake?
No, determining the relative age of a fossil relies on its position within the layers of rock, known as stratigraphy. If layers have been disrupted by an earthquake, it becomes challenging to establish the sequence of deposition accurately, making it difficult to determine the fossil's relative age relative to other fossils.
What is a fossil fuel that can not be separated from petroleum?
Petroleum is already a separated fossil fuel.
What is the method of determining whether a fossil is older or younger than other fossils found in the many layers of sedimentary rock is called what?
relative dating
What would be the two methods of dating fossils and explain each?
relative and absolute. relative is determining the relative order of past events, without necessarily determining their absolute age. Absolute is the process of determining an approximate computed age in archaeology and geology.
What is a fossil used to date surrounding rock layers called?
A fossil used to date surrounding rock layers is called a index fossil. Index fossils are particularly useful for determining the relative ages of rock layers in different locations.
What 3 requirements do index fossils have?
To be an index fossil, it must be widespread, commonly found (sometimes in groups) and have a short life span for which it lived. If a fossil meets all three of these requirements, it is considered an index fossil.
What is the relative age of a fossil that can be determined by comparing it to an index fossil is called?
The relative age of a fossil that can be determined by comparing it to an index fossil is called biostratigraphic dating. This method relies on the known age range of the index fossil to estimate the relative age of the fossil being studied.
What is the relative age of a fossil starfish?
the relative age of the rock where it was found.
Are Fossils used to correlate sedimentary rocks that are widely separated by using the rocks distinctive fossil content and applying the principle of fossil succession?
Yes, fossils can be used to correlate widely separated sedimentary rocks by comparing their distinctive fossil content and applying the principle of fossil succession, which states that older fossils in the rock layers are found at the bottom, and younger fossils are found in upper layers. By identifying similar fossil assemblages in rocks in different locations, geologists can establish a relative timeline of deposition and correlate the rocks.
How do you tell how old a fossil is by the rock layer?
You can determine the relative age of a fossil by looking at the position of the fossil in the rock layers. The closer a fossil is to the surface, the younger it is relative to fossils found deeper in the layers. To determine the absolute age of a fossil, scientists use radiometric dating techniques on the surrounding rocks to determine the age of the rock layer the fossil is found in.
What are fossil fuels separated from?
They are separated from the earth when we dig them up.They are separated from renewable fuel because they emit carbon dioxide when burnt.
