Tectonic Plates
Tectonic Plates: The picture that scientists now have of Earth's structure supports Wegner's original view of continental drift. Earth's outermost solid layer is known as the crust. It is on this layer that we humans and other animals and plants live. It makes up our mountains and plants and makes up the floors of our ocean and seas. The crust varies in thickness from about 5 kilometres under the continents.
The crust is rigid, inflexible and is split into many large sections that move about on Earth's surface. Each section is known as a tectonic plate.
Tectonic plates can be very large. For example, the whole of Australia and parts of New Zealand are on a single tectonic plate. Most of the crust under the Pacific Ocean is on another plate. There are seven extremely large tectonic plates that are bigger than most continents. There are another ten or so medium-sized ones and about 60 smaller plates.
