Earth is the only planet in the Solar System with plate tectonics. Basically, the outer crust of the Earth is broken up into regions known as tectonic plates. These are floating on top of the magma interior of the Earth and can move against one another. When two plates collide, one plate...
(1969, 1:5,000,000), Africa (1968, 1:5,000,000), India (1969, 1:2,000,000), and Australia (1972, 1:5,000,000). The International Geological Congress is sponsoring the preparation of a tectonic map of the world on a scale of 1:15,000,000; the work for the map is being ...
Since the start of plate tectonics, the number of recognized plates has grown considerably. This introduction examines how this number has grown with time. The first attempt at a global description of plates was done by Morgan (1968). Additional file1: Table S1 shows the plates that can be ...

Seven of the world's major tectonic plates make up around 84 percent of the Earth's total surface. This map shows those and also includes many other plates that are too small to label. Geologists refer to the very small ones as "microplates," although that term has loose definitions. The...
This graphic provides an explanation of plate tectonics, and highlights the seven major tectonic plates that make up Earth’s outer crust.

Thus, of Earth's tectonic plates, these two plates can be expected to best approximate the ALSS (Crough, 1983). In this study we evaluate the ALSS with a finite-element anal- ysis of the African intraplate stress field. The goal of this study is twofold: to estimate the magnitude of ...
A research team led by Harvard researchers looked for clues inancient rocks(older than 3 billion years) from Australia and South Africa, and found that these plates were moving at least 3.2 billion years ago on the early Earth. In a portion of the Pilbra Craton in Western Australia, one ...
