The hardness of a rock is determined by scratching it with a harder material.
The property of rocks that can be determined by whether they scratch glass is their hardness. This is measured on the Mohs scale, which ranks minerals based on their ability to scratch one another. If a rock can scratch glass, it indicates that its hardness is greater than that of glass, which has a hardness of about 5.5 on the Mohs scale. Conversely, if it cannot scratch glass, it is likely to be softer than this standard.
Rock types are determined by the mineral composition and texture of a rock. Rock names are often based on the predominant mineral present in the rock or the location where the rock is found. Geologists use various classification systems to categorize rocks based on their characteristics.

When you scratch a rock on something, it’s often referred to as testing the rock's hardness or conducting a scratch test. This is commonly done to identify minerals using the Mohs scale of mineral hardness, which ranks minerals based on their ability to scratch one another. The process can help determine the composition and characteristics of the rock or mineral being tested.
It is best determined by radiometric dating techniques which measure the decay of radioactive elements.

no
That depends what you scratch it with, what material the rock is made from, and how much force you apply when scratching.

If two rocks cannot scratch each other, then they would have to be of equal hardness. A harder rock can always scratch a softer rock.
