They are called lithospheric or tectonic plates, of which there are around 30 worldwide, encompassing the entire hard brittle surface layer of the Earth.

The theory of plate tectonics states that the lithosphere is broken into moving pieces of earth driven by convection currents located inside the mantle.

Marble is metamorphised limestone and a soft rock, so care is needed to quarry large slabs with a minimum of breakage. The most common modern method of marble quarrying is bench mining, where a huge wall of marble is cut loose from the quarry sides using diamond cutters, saws and hot torches. Dirt is piled up beneath this wall in order to cushion the fall when it comes loose. Once it is free and falls, the slabs are cut from the rock wall using the same types of tools and hoisted from the bottom of the quarry. Broken pieces are often crushed and sold as decorative stone for drives and gardens, while larger slabs are shaped and polished into slabs for building or other uses.
Tectonic Plates are the ground. They are large slabs of earth that float on top of the magma.
The movement of crustal or lithospheric plates is a part of the theory of plate tectonics.
The theory of plate tectonics explains large scale motion of the earth's lithosphere. Tectonic plates are rigid slabs of the earth's lithosphere (crust and upper mantle) in which float and move with the continents they carry.

The motion in the mantle is known as convection currents which helps move earth's slabs, known as plates. Convection occurs in the upper mantle known as the asthenosphere.
