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 else can I help you with?
What type of rock is Law of superposition?
The Law of Superposition is a geologic principle that states in a sequence of undisturbed sedimentary rock layers, the oldest layer is at the bottom and the youngest layer is at the top. It is not a type of rock; rather, it is a fundamental concept used in geology to determine the relative ages of rock layers.
What is the oldest sedimentary rock?
In an undisturbed strata, the oldest layers are at the bottom. It's called the law or principle of superposition.
Which rock is mostly likely a sedimentary rock?
One showing an igneous nature.
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
According to the law of superposition the lowest layer in a cross section of rock is what?
According to the law of superposition, the lowest layer in a cross section of rock is the oldest, as sedimentary rocks are typically laid down in sequence with the oldest rocks at the bottom and the youngest at the top.

Which of the principle apply to sedimentary rock?
yes
How can the law of superposition be used to determine the relative age of sedimentary rock?
The law of superposition states that in an undisturbed sequence of sedimentary rocks, the youngest rocks are on top and the oldest are at the bottom. By observing the layers of sedimentary rock, geologists can determine the relative ages of the rocks based on their position in the sequence. The principle helps establish a chronological order of events in Earth's history.
Where are fossils preserved?
it is mostly preserved in sedimentary rock
Which rock is mostly likely a sedimentary rock?
One showing an igneous nature.

To date a sedimentary rock layer between two igneous rock units geologists use radiometric dating and assume that the sedimentary layers are?
Geologists use radiometric dating of the igneous rock units above and below the sedimentary layer to establish a time range for the sedimentary rock. They assume that the sedimentary layers are younger than the underlying igneous rock and older than the overlying igneous rock, based on the principle of superposition. This allows them to estimate the age of the sedimentary layer by determining the ages of the surrounding igneous rocks.
Which rock is mostly likely a non sedimentary rock?
One showing an igneous nature.
Why are fossils found mostly in a sedimentary rock?
Because when the lava killed the animals, their remains stayed in the lava and dried to become sedimentary rock.
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...
