Tectonic Activity

Tectonic Activity The continents of the world are all separated by different tectonic

plates which when collide is called Tectonic Activity. There are

different forms of tectonic activity and different processes and

landforms, which are involved during and as a result of the

collisions. As and when these collisions are going to take place we

can't determine because current technology hasn't allowed us to dig as

far into the earth to the point of pressures which causes the plates

to collide. These pressures are believed to be eruptions of liquid

magma deep inside the earth.

The plate tectonic theory was first proposed in 1915 by a man named

Alfred Wegener, who was one of the first to identify that the

continents of earth look like they fit together in a jig saw puzzle,

but what separates him is the fact he suggested that the earth had

separated over a period of time, introducing the future theory of

plates. As Wegener had no explanation of why the earth's crust had

separated many geologists turned against his ideas, these people were

called anti-mobilists. The only evidence that was proved to help

Wegener's theory was that palaeontologists had found fossils of

similar species on different continents, which suggests that the same

species were once on the same area of land with the only explanation

being that they had been separated by the motion of land. As years

passed more and more evidence was uncovered to support the idea of

plates move constantly over time. After the Second World War

seismometers were installed into the earth and showed that
