So like idk if I was the only one who was terrified when I was younger and still in elementary school learning of plate tectonics because like sublimation and all that because I was terrified that just all of the continents would disappear because they would be sublimated but I finally found out how not to be terrified of that. I'm now taking astronomy in college and it's explaining how the geology of the Earth works in relation to what happens in the general solar system. So turns out differentiation in the Earth's layers is a thing and the continents are of a lower density than the seafloor plates so the continents will always stay on top. I had that fear in the back of my mind for years until now and all that could've been avoided had teachers just said that it's lower density than the seafloor so the continents just won't up and...y'know...disappear...
