back of iPhone scratch

Hello Everyone,

I’d like to know if these lines at the rear glass of my iPhone 12 are scratches or cracks. I’ve inspected the lines closely and they’re not as deep as they look and there are only 3 of them on the right side. None of them are touching the edge of the Phone. So this is what happened, I dropped my phone around half of an inch high on top of the kitchen counter due to the fact that I was in a hurry to get to somewhere. As it touched the countertop it slammed lightly. Than when I came back I discovered these lines. Can someone tell me if it’s a Crack or if it’s just a deep or minor scratch.
