What?
Scratching a mineral with a nail is a test of hardness. It helps determine the relative hardness of the mineral compared to known substances on the Mohs scale of mineral hardness.
Diamond is the hardest mineral and is the most resistant to scratching. Its hardness is assigned a value of 10 on the Mohs scale of mineral hardness, making it the top-ranked mineral in terms of scratch resistance.
Iron is durable and resistant to scratching, but it is not scratch-proof. Iron can develop scratches, especially when in contact with harder materials like diamond or abrasive minerals. Regular maintenance and care can help minimize scratching on iron surfaces.
It is called a streak and its purpose is to find the hardness of the mineral.
The scale that compares the resistance of the surfaces of minerals to scratching is called the Mohs scale of mineral hardness. It ranks minerals on a scale from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by other minerals.
It defends itself by growling and biting its enemy and scratching it
Scratching and Biting.
It keeps on scratching itself.

Reasons why your dog is scratching itself would be because it might have fleas, allergies, walking dandruff, skin infections, ticks and lice, fungal infections or seborrhea.
Music itself is a whole other world, I'm hardly scratching the surface of it.
The same way other chickens do - by pecking, scratching, and kicking.
The animal kept scratching itself. ------
If you can tell what your hamster looks like when it is cleaning itself you will be able to tell if it has fleas because it will be scratching itself more than you have ever seen it do.
It depends on the Cockatiel itself, but most of the time, no, they are not ticklish. :)But some do react to light scratching around the stomache area.
