In short, yes. Granite is a natural stone, and although it is hard and can be scratch resistant, it still can be scratched.
In order to protect granite (and other natural stone) a special coating is applied. Some natural stones are more scratch resistent, some are much less. In order to protect granite from scratching, this veneer or protection must be applied regularly (usually at least once a year).
Granite does not scratch easily. You can scratch granite with other granite or a tool designed to cut granite but that is about it. Cutting directly on your granite is not recommended as it can dull your knife but it should not create scratches in the stone.
Granite is very soft and can be scratch away very easily. Granite counter tops should be sealed and polished to prevent this from happening.
No
NO! that is a granite marketing lie. Coffee mugs and plates will scratch it.
Most likely it was a loose chunk of granite that popped off, got under the pad and caused the scratch. It happens.
Usually the mineral deposits a certain color or colors that you wouldn't see otherwise.
their both scratch resistente
Granite can exist in several colors. The colors are based on the ratio of feldspar, quartz, and mica.
Granite and Basalt: 1. Granite is formed from magma that cooled slowly, so it has a coarse-grained texture. It may be pink, white-gray or light to moderate yellow. It contains the minerals feldspar, quartz and mica. Its mineral grains are similar in size. Granite is hard to scratch with a fingernail. 2. Basalt is formed from lava that cooled rapidly, so it has a fine-grained texture. Its mineral grains are so tiny that they can be seen only through a microscope. It may be black or dark green. It contains the minerals feldspar and olivine. Like granite, basalt is hard to scratch with a fingernail.
Granite countertops are great for both kitchens and bathrooms. They provide a durable surface that is easy to clean, which can be an important factor when looking at kitchen or bathroom countertops. Granite is also stain resistant, so it will not absorb any food colorings or liquids spilled on the counters. Plus, granite has natural beauty with its variety of colors and patterns that make it stand out in any room!

Corrosive? NO, but will scratch the paint if wiped/not rinsed off.
