Lithosphere is divided into number of huge slabs of rock, called ______.
The lithosphere is divided into very big sized slabs known as tectonic plates. The heat from the mantle makes the rocks at the bottom of lithosphere slightly soft. This causes the plates to move. The movement of these plates is known as plate tectonics. So, the above information shows that Lithosphere is divided into a number of huge slabs of rock, called tectonic plates. Thus the correct option is B. Other options are not suitable.
