To identify a mineral, you can examine its color, which may provide initial clues, though it can be misleading due to impurities. Hardness is another critical characteristic, measured by the Mohs scale, indicating how easily a mineral can be scratched. Additionally, the mineral's luster, or how it reflects light, can help distinguish it, as it may be metallic, glassy, or dull.
They look at the elements of the landmass.
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!
Look, smell/taste (these are related) and texture.
To find the hardness of a mineral, you would look at its ability to resist scratching by harder substances. This is typically measured using the Mohs scale of mineral hardness, which ranges from 1 (very soft) to 10 (very hard).
Living things typically exhibit characteristics such as growth, reproduction, response to stimuli, metabolism, and organization. Look for traits like movement, respiration, sensitivity, and the ability to adapt to the environment to help determine if an object is a living thing.
Look if is solid, is it formed in nature.
The scratch test, use a series of mineral with known hardness and scratch the mineral. From softest to hardest, and note where a scratch is made. You can also look for distinctive physical characteristics.
The first step would be to determine what type of rock it is, based on the classifications of igneous, sedimentary, or metamorphic. All three have sets of characteristics common to them that indicate their method of formation. Beyond that, to find the actual place of origin geographically of a specific rock sample that may have been transported by erosional processes far from its place of origin, you would have to have some knowledge of formations--bodies of rock with specific characteristics that are found only in that formation. Factors to look at in the sample would be texture, type, fossils, and mineral composition.
It looks for distinguishing characteristics called virus signatures.
They look at the elements of the landmass.
When classifying organisms, scientists look for three main things: shared physical characteristics, genetic similarities, and evolutionary relationships. They observe and compare features such as anatomy, behavior, and molecular traits to determine how closely related different species are and how they should be classified into groups or categories.
To determine if a plant organ is a fruit, look for characteristics such as containing seeds, developing from the ovary of a flower, and being a mature ovary that has ripened.
You start by scratching it and seek it's hardness. When you find its hardness, compare it to another mineral with the same hardness. If they look exactly the same, and have the same arrangements of minerals, then they are the exact same mineral.

It looks for pre-programmed distinguishing characteristics called virus signatures.
The four questions used to determine if a substance is a mineral are: Is it naturally occurring? Is it inorganic? Is it a solid? Does it have a specific chemical composition and a crystalline structure?
