What are two major methods of dating artifacts or fossils?
Two major dating methods applied to artifacts and fossils are stratagraphic dating (based upon the particular layer of rock of sediment in which the object is found) or radiometric dating (which is based on the decay rates of certain radioactive isotopes). The type of radiometric dating used depends greatly on the approximate time period you are studying and so varies depending on if the material you are studying is an artifact or a fossil. The method most commonly used in archaeology is carbon dating.
Which method of archaeological dating determines an artifact's age in relation to other objects?
Dating using the isotope carbon-14. Carbon-14 dating is considered an "absolute" dating method as it will give a quantitative age (plus or minus an error). Relative dating techniques are typically based around the law of superposition which in an archaeological context broadly states that objects are buried by sediment in relation to their age whereby the older an object, the deeper it is buried. This form of ageing allows you to state that one object is older or younger than another, but not by how much or the actual age of either object, hence relative dating!

What is another word for tomb?
A Layer
What is the lower part of the oceanic crust?
The lower part of the oceanic crust is called the gabbro layer. It is formed when magma solidifies below the Earth's surface, creating a rock type that is rich in minerals like silica and magnesium. The gabbro layer is typically found beneath the basalt layer of the oceanic crust.
What were ziggurats built with?
Ziggurats were typically constructed with sun-dried bricks made from clay and sometimes reinforced with baked bricks or bitumen. These structures were built layer by layer, with each level slightly smaller in size than the one below it, creating a stepped pyramid shape. The exterior surfaces were often plastered and painted in vibrant colors.
Can fossils be used to determine the relative ages of rocks layers?
fossils can be used to determine the relative age of rock layer by using the classification of fossils to find the relative ages of rocks in which fossils are found. :] hoped i helped you out.

Which example describes method of relative dating?
using fossils to determine the oldest rock layer in a canyon
What fossil used to compare the relative ages of fossils?
An index fossil. An index fossil's age is known, allowing scientists to know the relative age of other fossils based on their position relative to the index fossil. (Ex. If a fossil is deeper in the earth, it is older than the index fossil)
How fossils can be used to determine the absolute and relative age of a sedimentary rock layer?
Perhaps by carbon dating and by comparing with the evolution and dominance of various organisms in the geological time scale.
What is the relative age of fossils found at the top layer of rock?
They are called index fossils, fossils of organisms that were widespread, evolving quickly, and only appeared in the geologic column for a specific length of time.
Why are index fossils so important to geologists?
Index fossils are very important to geologists because they identify geological time periods. Index fossils are found within a specific layer of rock- So when one finds the age of the rock layer, that is also the age of the index fossil.
Which of the following is most accurate in helping pinpoint a time period on the geologic time scale during which a rock layer was formed?
Fossils found in the rock layer are the most accurate method for pinpointing a time period on the geologic time scale. By identifying the specific types of fossils present, scientists can determine the age of the rock layer relative to the known age ranges of those fossils.
What does relative dating mean in biology?
Relative dating in biology refers to estimating the age of a fossil or rock layer based on its position relative to other fossils or rock layers. It does not provide an exact age, but rather an estimation of the order of events. This method relies on principles like superposition and stratigraphy to determine the relative age of different geological features.
Which layer is most likely to contain fossils that resemble existing species?
new layer of the fossils
What do geologist use index fossils for?
to date a rock layer and other fossils within that layer
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.
