The answer is implicit in your question - they are physical "objects" of different characteristics so their appearances differ. That's the first way to determine a rock's type: look it it!
There are thousands of different types of rocks.
The three main types of rock are igneous (formed from cooled magma or lava), sedimentary (formed from compressed sediment), and metamorphic (formed from existing rock that has been subjected to heat and pressure). Each type has unique characteristics and formation processes.
Different rock are made by the many different events that lead to their creation. Other rock just have different amounts and types of minerals, creating different rock with hardness, texture, color, and shape patterns.
Different kinds of rocks are formed through different geological processes. Igneous rocks form from the cooling and solidification of magma. Sedimentary rocks are created from the accumulation and cementation of sediments. Metamorphic rocks result from the alteration of existing rocks through heat and pressure. These processes lead to a wide variety of rock types with unique characteristics.
Coal and Sandstone are two types of sedimentary rocks.
Each of the rocks form in a different way.
Differential media is able to distinguish different species or types of microorganisms based on an observable change in the colonies or in the medium. This type of medium contains specific nutrients or indicators that allow for differentiation between microorganisms based on their metabolic capabilities or other physiological characteristics.

There are thousands of different types of rocks...What type of rocks in particular?
Physical properties of matter, such as color, texture, density, and melting point, can be observed without changing the composition of substances. These characteristics help identify and classify different types of matter based on their observable features.

Yes, the type of rock used can affect the properties of the resulting glass, such as its color, transparency, and strength. Different rocks have varying compositions and impurities that can influence the characteristics of the glass when melted and formed. For example, silica-rich rocks like sand are commonly used to make glass as they provide a good source of silicon dioxide, the main component of glass.
sedimentary rocks
There are three different rock types which are called igneous; rocks formed by the cooling of lava and magma (molten rock), sedimentary; rocks formed when weathered particles of other rocks and fossils are compacted and cemented together at the bottom of rivers and the sea and metamorphic; formed when other rocks are changed by heat and pressure underground. There are many individual rocks within each of these categories.
There are lots of different types of rocks in the world.
