An object or surface that's scraped is rough and uneven because something has scratched away at it.
When we scrape something, like paint off a wall or an old sticker from a window, what's left behind can be quite messy. This word "scraped" often refers to a surface that's been damaged by being rubbed against something hard or sharp. Imagine trying to clean up after a rough renovation - the walls might be scraped and scratched from hammers and saws. If you spill paint on your favorite table, it'll get scraped too if you try to scrape off the stain with a metal tool.
