J.T Wilson was the one who came up with the theory of plate tectonics.
Harry Hess came up with the theory of sea-floor spreading.
Alfred Wegener came up with the theory of continental drift and Arthur Holmes proposed a suitable mechanism for this to occur (mantle convection).
But plate tectonics is the theory which suggests that the Earth's crust is made up of solid plates moving relative to each other. Plate tectonics and the plate tectonics theory aren't really two separate things. However plates are pieces of the Earth's crust which are moving.
Plate Tectonics
The scientific theory is called plate tectonics, which describes the movement and interaction of Earth's lithosphere plates. This theory explains phenomena such as earthquakes, volcanoes, and mountain formation.
Alfred Wegner essentially.
Plate Tectonics is a theory which was originally invented by the German geologist Alfred Wegener in the 1930s.Sorry but this is wrong, Alfred wegener came up with the theory of continental drift. JT Wilson came up with plate tectonics.
The theory of plate tectonics says that the Earth's lithosphere is divided into "plates" that are determined by overall movement.The theory combines ideas on seafloor spreading and continental drift
I think that continetal drift replaced his theory
Alfred Wegener was the first to publish his theory although other people thought it
Tectonic plates are large slabs of solid rock that make up the Earth's outer shell. These plates move and interact with each other, leading to geological phenomena such as earthquakes, volcanic activity, and the formation of mountains.
These plates make up the top layer of the Earth called the lithosphere. Directly under that layer is the asthenosphere. It's a flowing area of molten rock.
The lithosphere layer of the Earth is made up of plate tectonics. This layer consists of the Earth's crust and the upper part of the mantle and is broken into several large and small plates that float on the semi-fluid asthenosphere below, creating the movement of plate tectonics.
the theory that earth's crust and solid upper part of the mantle are made up of about 20 huge plates that are always moving very slowly
