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.
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.
In an undisturbed strata, the oldest layers are at the bottom. It's called the law or principle of superposition.
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 the oldest, as sedimentary rocks are typically laid down in sequence with the oldest rocks at the bottom and the youngest at the top.

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.
The law of superposition states that in undisturbed sedimentary rock layers, the oldest layers are at the bottom and the youngest are at the top. This principle applies primarily to sedimentary rocks because they are formed from the accumulation of sediments over time, with new layers deposited on top of older ones. In contrast, igneous and metamorphic rocks often undergo processes like intrusion and deformation that can disrupt this layering, making the law of superposition less applicable. Therefore, the organized stacking of sediments in sedimentary rocks provides a clear chronological record of geological history.

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.

Because when the lava killed the animals, their remains stayed in the lava and dried to become sedimentary rock.
