Why do they move?

Who came up with the idea of plate tectonics? How long ago did that person come up with the theory? What was the theory before plate tectonics?

Alfred Wegener came up with the idea of plate tectonics. He came up with the theory about 100 years ago. The theroy before plate tectonics was continental drift.

Alfred Wegener had thought of the idea for tectonic plates.

In 1912, Alfred Wegener made the theory of Continental Drift. 50 years later, his theory developed farther into Plate Tectonics.

Alfred Wegener came up with the idea of tectonic plates over 100 years ago, and before his theory was the continental drift.

1912 Alfred Wegener named these plate tectonic plates.

Dillonleighton said...

According to the generally accepted plate-tectonics theory, scientists believe that Earth's surface is broken into a number of shifting slabs or plates, which average about 50 miles in thickness. These plates move relative to one another above a hotter, deeper, more mobile zone at average rates as great as a few inches per year. Most of the world's active volcanoes are located along or near the boundaries between shifting plates and are called plate-boundary volcanoes.

The person was Alfred Wegener, he discovered it about 100 years ago and the theory before was continental drift.

In 1912, a man named Alfred Wegener.

it was Alfred Wegener in about 1912

Alfred Wegener made the theory on 1912 and people thought that the ground was flat and featureless, it happened 104 years ago.

Plate tectonics (from the Late Latin tectonicus, from the Greek: τεκτονικός "pertaining to building")[1] is a scientific theory that describes the large-scale motion of Earth's lithosphere. This theoretical model builds on the concept of continental drift which was developed during the first few decades of the 20th century. The geoscientific community accepted the theory after the concepts of seafloor spreading were later developed in the late 1950s and early 1960s.

Alfred Wegener,1880,and the expanding Earth.

Alfred Wegener discover the plate tectonics in 1910 the theory before Alfred Wegener's was that the earth was constantly growing but if that was the case the earth would pop like a ballon.

Hannah M said...

A man named Alfred Wegener, he came up with the idea in 1912. Before that they thought it was called continental drift.

Richie P. said...

In line with other previous and contemporaneous proposals, in 1912 the meteorologist Alfred Wegener amply described what he called continental drift, expanded in his 1915 book The Origin of Continents and Oceans and the scientific debate started that would end up fifty years later in the theory of plate tectonics.

I do not own any of the following information, all credit goes to the original owner of the article.

Plate tectonics (from the Late Latin tectonicus, from the Greek: τεκτονικός "pertaining to building")[1] is a scientific theory that describes the large-scale motion of Earth's lithosphere. This theoretical model builds on the concept of continental drift which was developed during the first few decades of the 20th century. The geoscientific community accepted the theory after the concepts of seafloor spreading were later developed in the late 1950s and early 1960s.

The lithosphere, which is the rigid outermost shell of a planet (on Earth, the crust and upper mantle), is broken up into tectonic plates. On Earth, there are seven or eight major plates (depending on how they are defined) and many minor plates. Where plates meet, their relative motion determines the type of boundary; convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries. The lateral relative movement of the plates typically varies from zero to 100 mm annually.

A scientist, named Alfred Wegner, came up with the theory that the continents once joined together and then moved away from each other because of the current in the sea. Then it became the plate tectonic theory.
