In plate tectonic theory, we knew that if you had plates collide, it made sense: they would crush into one another, you would thicken the crust, you'd uplift it.
Dalam teori lempeng tektonik, kita tahu bahwa jika dua lempeng bertabrakan, ini masuk akal, lempeng itu akan saling berhimpitan, lalu menebalkan kerak bumi dan mengangkatnya.
