They are used to determine the relative ages of rocks by stating that younger rocks lie above older rocks, and that rocks that cut through a layer are younger than the existing layer.

relative age
A horizon is often darker than B horizon or C horizon because it is the topsoil and the topsoil might be covered with litter. The litter decompose and as you know become soil and it will be fresh soil. So the fresh soil is darker than B and C horizon
Index fossils
The C horizon rocks are the least weathered and least affected by soil formation processes. They are typically made up of parent material, representing the unaltered material from which the soil developed. In contrast, the B horizon rocks are generally more weathered and altered by soil-forming processes such as leaching and translocation of minerals.

Rocks have color, grain, specific density, and relative hardness.

The A horizon has smaller rocks and mineral particles than any other layers.....
No, its erosion that causes rocks to change
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.
Determining the order of events and the relative age of rocks by examining their positions in a sequence is called stratigraphy. This technique involves studying the layers of rock (strata) and using principles like the Law of Superposition to understand the chronological order of rock formations.
The principle of relative dating helps geologists determine the age of rocks that are separated by distance. This principle states that in an undisturbed sequence of rock layers, the youngest rocks are at the top and the oldest rocks are at the bottom. By comparing the relative positions of rock layers in different locations, geologists can infer the relative ages of the rocks.
No, sedimentary rocks are commonly used for relative age determination due to their layering and formation process. However, other types of rocks like volcanic rocks and metamorphic rocks can also be used to determine relative age based on principles of superposition, cross-cutting relationships, and faunal succession.
