what is the basis on which subdivisions are made
Fossils are made naturally by Geological processes.
The four principal compositional subdivisions of the Earth are the inner core, outer core, mantle, and crust. The inner core is solid and composed mostly of iron and nickel, the outer core is liquid and also made of iron and nickel, the mantle is a solid rocky layer, and the crust is the outermost layer that we live on.
No, the noun scale is not a material noun. A material noun is a word for something that other things are made from. Some examples are:goldplasticironmilkleathercottonflourcopperrubberpapercementpetroleum
Devils Tower is a natural geological formation, specifically an igneous intrusion that formed underground and was exposed through erosion. It is not man-made.
Devil's Tower is in Wyoming. It is a geological feature made of an igneous rock called phonolite porphyryl. The site is considered sacred to many tribes in the area.
Subdivisions are typically made based on geographical boundaries, population size, administrative purposes, or political organization. They can also be created to organize and manage resources, provide services, or facilitate governance within a region. The specific criteria for subdivision can vary depending on the country or jurisdiction.
By geological events.
The longest periods of the geological time scale are eons. Each eon is divided into eras and each era is made up of periods, which are further divided into epochs. Each division ended when a significant geological event occurred, such as a major ice age ending or a meteor impact resulting in a mass extinction of animal life, etc.

Resources that are found naturally and not man-made
The geologic time scale is a framework that organizes Earth's history into eons, eras, periods, epochs, and ages. While the broad structure of the time scale remains relatively stable, refinements and adjustments are made as new research and insights emerge. These changes help to improve our understanding of Earth's history and the relationships between different geological events.
Vertical scale is often larger in profiles of Earth to emphasize and show variations in elevation more clearly. This allows for a more detailed representation of the topography and geological features of the Earth's surface. Additionally, the magnitude of vertical changes is typically greater than horizontal changes, especially in mountainous regions, making the vertical scale more relevant and easier to interpret.
Modern thermometers are made of alcohol or Mercury, and uses the Fahrenheit scale and the Celsius scale.

Fossils are made naturally by Geological processes.
The chromatic scale is made up entirely of half steps.
