they are useful by showing where the fossil is buried then on that certain layer, it will be studied to know the age.

Moon rocks resemble rocks from the Earth's crust layer. They are predominantly composed of igneous rocks like basalt and anorthosite, similar to those found on Earth's crust.
In order to be useful in determining the relative ages of rocks, an indicator must provide different indications for rocks of different ages, right? So how could something which doesn't change over time be useful?
The layer of the Earth that contains rocks, minerals, and soil is the Earth's crust. It is the outermost layer of the Earth and is divided into tectonic plates that float on the semi-liquid layer below called the mantle.
the outer most layer of earth is CRUST
The Asthenosphere.
Rocks are extracted from the Earth's crust, which is the outermost layer. This is where most of the solid rocks are found, including those suitable for mining and quarrying.
The layer of Earth made up of loose rocks and soil is the Earth's crust. It is the outermost layer of the Earth and is where most geological activity, such as earthquakes and mountain-building, occurs.
LITHOSPHERE.
A garden and rocks can be found in the Earth's crust, which is the outermost layer of the Earth. This layer includes the soil, where plants grow, as well as various types of rocks that make up the landscape. The crust varies in thickness and composition, but it is where most terrestrial life exists.
The layer of the Earth composed of rocks rich in silicon and aluminum is the crust. The crust is the outermost layer of the Earth, and it includes both the continental crust, which is thicker and primarily made up of granitic rocks, and the oceanic crust, which is thinner and predominantly composed of basaltic rocks. These rocks are characterized by their higher concentrations of silicon and aluminum compared to other layers of the Earth.
The layer of the Earth that is primarily made of rocks and soil is called the crust. The Earth's crust is the outermost layer of the planet and is divided into two types: continental crust (underlying land masses) and oceanic crust (underlying ocean basins).
