Which type of dating provides an absolute age for a given fossil describe how this is done?
I think it's Radioactive dating, I've been reading for my homework and I can't seem to find carbon dating anywhere in the chapter which I've reread about 3 times so I'm going to assume its radioactive because relative dating is the estimation of a fossils age compared with other fossils.
What else can I help you with?
What must be true for a fossil organism to be useful as a index fossil?
The absolute age of the index fossil was determine by radioactive dating or another absolute method
What are two ways to date fossils?
Two ways to date fossils are relative dating, which involves determining the age of a fossil in relation to other fossils or geological layers, and absolute dating, which provides a numerical age for a fossil using techniques like radiometric 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.
Can you date a fossil by seeing how deep the rock is?
No, dating a fossil by the depth of the rock is not a reliable method. Fossils are usually dated using radiometric dating techniques, which analyze the decay of radioactive isotopes in the rocks surrounding the fossil. This provides a more accurate estimation of the fossil's age.
How do you determine the absolute age of a fossil?
How do you find a fossil's absolute age? The absolute age (or direct dating) of a fossil is determined by knowing the age of the surrounding rock. The most common way is by radiometric dating, a method that relies on the natural radioactivity of certain elemental isotopes. Different isotopic elements-such as uranium, rubidium, argon, and carbon-have varying (but constant) rates of radioactive decay. This constancy provides a "radiometric clock," allowing scientists to analyze rock samples and measure the relative ratios between the "parent" and "daughter" isotopes. The ratios reveal the age of the rock layer, and thus, the age of the associated fossil. As with many scientific measurements, although the method is called "absolute," the dates are not exact and there is room for potential errors.

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.
Main differences between relative dating and absolute dating?
Relative dating determines the age of a rock layer or fossil by comparing it to other layers, while absolute dating provides a specific age in years. Relative dating relies on stratigraphy and the Law of Superposition, while absolute dating uses techniques like radiometric dating to provide numerical ages. Both methods are used in combination to establish a more accurate timeline of Earth's history.
How can someone find the absolute age of a fossil?
By using radiometric or radiocarbon dating.
Does Absolute age examines the position of rocks in a sequence?
No, absolute age determines the actual age of a rock or fossil through various dating techniques like radiometric dating. It does not focus on the position of rocks in a sequence but rather provides a specific numerical age.
What does relative dating provides?
It provides how old a rock/fossil is compares to the rocks/fossils around them.
How is the absolute age of the fossil different from the relative age?
The absolute age of a fossil provides a specific numerical age in years, usually determined through radiometric dating techniques. Relative age, on the other hand, only allows us to determine the fossil's age in relation to other fossils or rocks, based on their layering or sequence in the rock record.
What are two ways geologists determine the age of fossils?
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)
What are two ways to date fossils?
Two ways to date fossils are relative dating, which involves determining the age of a fossil in relation to other fossils or geological layers, and absolute dating, which provides a numerical age for a fossil using techniques like radiometric dating.
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 is absolute age?
Absolute age refers to the exact age of a rock, fossil, or other geologic feature in years. It is typically determined using radiometric dating techniques that measure the decay of radioactive isotopes within the object. This method provides a more precise and accurate age compared to relative dating methods.
What is the purpose of absolute dating?
Absolute geologic age is determined through radiometric dating, and is the most precise method for determining the age of a rock or fossil within a small range. Relative geologic age is determined by the index fossils that may be contained within the rock that indicate a much broader range of possible ages based on the time the organism existed on Earth.
