Pangaea The Earth is divided into three layers -the crust and the mantle and the core. We live on the crust and it’s the thinnest layer -the mountains to the desert to the ocean floor. Two thirds of the Earth’s mass is the mantle in between the core and the crust The core is a mystery but through volcanoes some of the mantle reaches us. Hey, it is thought Pangaea was when the continents were a single landmass. Hey, it was called Pangaea once when the continents were all joined as one. The outermost layer of the crust is the lithosphere and it is made of tectonic plates which divide the Earth into puzzle-like pieces. Hey, it is thought Pangaea was when the continents were a single landmass. Hey, it was called Pangaea once when the continents were all joined as one. Two plates meet at a convergent boundary or move away from a divergent one, or slide past each other at a transform boundary and this is where the earthquakes come from. Hey, it is thought Pangaea was when the continents were a single landmass. Hey, it was called Pangaea once when the continents were all joined as one.
