Tectonic Plates float on the semi-molten surface of the mantle.
Earth's tectonic plates are currently drifting on the semi-fluid asthenosphere, which is part of the upper mantle beneath the crust. This layer is composed of partially molten rock that allows the rigid plates to move slowly due to convection currents caused by heat from the Earth's interior. The movement of these plates is driven by various geological processes, including mantle convection, slab pull, and ridge push. This drifting leads to various geological phenomena, such as earthquakes, volcanic activity, and the formation of mountain ranges.

Tectonic Plates
Unequal heat distribution.
Their evidence comes from rocks at earths surface.
The Earth's plates are presently drifting on the Earth's mantle, which is a semi-solid layer of rock beneath the Earth's crust. This movement is driven by convection currents in the mantle caused by heat from the Earth's core. The process is known as plate tectonics.
the convection currents in the mantle under the earths curst is moving the broken plates in earths lithosphere causing the plates slide across the lithosphere. this process is called tectonics. (jon lay wrote this,)
The crustal plates (made mostly of low density granitic rock) float on the mantle (made mostly of high density basaltic rock). Convection cells in the mantle move the floating crustal plates around.
Techtonic plates
The rigid lithosphere is the zone on Earth's surface that forms drifting tectonic plates. These plates float on the semi-fluid asthenosphere below and interact with each other at plate boundaries, leading to various geological phenomena such as earthquakes and mountain formation.
The tectonic plates below earths surface shape earths landforms
The main force driving the drifting of continents is plate tectonics. This is caused by the movement of the Earth's lithosphere plates over the semi-fluid asthenosphere beneath them. The plates can converge, diverge, or slide past each other, leading to the drifting of continents over long periods of time.
Tectonic Plates.
The worlds tectonic plates slide on the earths mantle.
there are 8 plates
The lithosphere.
because of the tectonic plates under the sea were drifting actively
