Antarctica is a continent made of rock.
Not entirely actually! I just learned earlier today (Wikipedia) that "if its ice is considered not as land, but as water, it is not a single landmass, but several landmasses of much smaller area, since the ice-bedrock boundary is below sea level in many regions of the continent"
TIL that glacier ice is considered a type of mono-mineralic rock: https://www.usgs.gov/faqs/glacier-ice-a-type-rock
So did I! Thanks!
You're confusing a continent with a craton. A continent is an entire geographic region. It's not a singular object.
