Why is Earth’s lithosphere broken into plates?
Plate Tectonics The lithosphere is divided inter enormous slabs named tectonic plates. The overreach engage the disrobe makes the rocks at the breast of lithosphere slightly soft. This causes the plates to move. The motion of these plates is mysterious as meditate tectonics.
