How do scientists use sedimentary rock to determine a fossils relative age?
Scientists use sedimentary rock to determine a fossil relative age by studying the rock.
How do you determine the sequence of events in rock layers?
By the law of superposition: Oldest at the bottom and youngest at the top.
Which phrase describes the relative age of a rock?
refers to how old a certain rock or rock layer is compared to another rock
What are three types of clues to the relative age of rock layers other than the law of superposition?
To determine relative age, geologists also study extrusions and intrusions of igneous rock, faults, gaps in the geologic record, and inclusions.
What do geologists use to determine the relative ages of a rock?
Relative dating refers to the process of determining the age of a rock, feature, or fossil by comparing it to the rocks around it. To use relative dating, you need to look at the order each rock layer was deposited.
How do a geologist use the principle of superposition?
A geologist uses the principle of superposition to determine the relative ages of rocks and sedimentary layers. This principle states that in undisturbed layers of rock, the youngest layers are at the top while the oldest layers are at the bottom. By observing the order in which different rock layers are stacked, a geologist can infer the sequence of events that happened over time in a particular location.
What two things did 19th century scientists do to determine the relative age of sedimentary rock all over the world?
They studied fossils and applied the principle that old layers of rock are below young layers! -
Does the law of superposition helps geologist determine the absoloute age of a rock layer?
no, the relative age
What type of rock is Law of superposition?
Sedimentary
How do geologist use the principle of superposition?
The principle of superposition states that a rock layer on top of another is younger than the one beneath it. Geologists use the principle of superposition to determine the relative ages of rock layers.
How do scientists use sedimentary rock to determine a fossils relative age?
Scientists use sedimentary rock to determine a fossil relative age by studying the rock.
One of the key principles of relative dating is the law of superposition which states that?
Younger layers of sedimentary rock are deposited on older layers
How do you determine the sequence of events in rock layers?
By the law of superposition: Oldest at the bottom and youngest at the top.
Which phrase describes the relative age of a rock?
refers to how old a certain rock or rock layer is compared to another rock
What are three types of clues to the relative age of rock layers other than the law of superposition?
To determine relative age, geologists also study extrusions and intrusions of igneous rock, faults, gaps in the geologic record, and inclusions.
Why does the law of superposition apply mostly to sedimentary rock?
The law of superposition applies mostly to sedimentary rocks because the law of superposition states that each layer is older than the one above it and younger than the one below it. Sedimentary rock is formed mostly by sediments which have been laid down over time, and then lithified into rock. Igneous and metamorphic rocks have different processes of formation which which are more to do with heat and pressure, and less to do with sequential deposition.
What is called when organisms are trapped in sedimentary rock?
when an organism is trapped in sedimentary rock, it will die and the organism will slowly decay, but it won't decay altogether and you get a fossil. the older the fossil is the lower down it will be in a sedimentary layer. that's called superposition...
