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.

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.
