Plate tectonics (from Greek "έκ"ων, tektōn "builder" or "mason") is a theory of geology that has been developed to explain the observed evidence for large scale motions of the Earth's lithosphere.
plate tectonics The movement of the plates that make up the surface of the Earth.
Plate Tectonics the study of the interactions among the plates which make up the Earth's crust

Plate tectonics is the geological theory that proposes the lithosphere is composed of tectonic plates that are in constant motion relative to each other.
plate tectonics the collective geologic processes that move the crustal plates of the earth and cause continental drifting and seafloor spreading
platelet A tiny, incomplete cell in the blood that releases substances initiating blood clotting.
upper mantle that move and adjoin each other along zones of seismic activity. The theory that the crust and part of the mantle are divided into plates that interact with each other causing seismic and tecotnic activity is called plate tectonics.
When combined with plate tectonics, fossils provide evidence of distributions and dispersals of ancient species. For example, South America had a very distinct marsupial mammalian fauna until the land bridge formed between North and South America.
Biogeography studies the spatial distribution of organisms on the Earth,[64] focusing on topics like plate tectonics, climate change, dispersal and migration, and cladistics.
