Plate tectonics is a theory which states that Planet Earth's lithosphere the crust and the upper mantle is made up of solid plates which float on an underground ocean of magma. These plates are proven to move around. This movement results in earthquakes in the short term, and the movement of continents over hundreds of millions of years. Tectonic plates can range from the very large-such as the Eurasian Platewhich includes all of Europe and Asia and large chunks of the Arctic Ocean and South China Sea.
They can also be small, which includes the part of the Atlantic surrounding the Caribbean islands and a small part of Central America.
These plates touch each other at plate boundaries. There are three different types of boundaries. Transform boundaries are places where the edges of the plates grind against each other. These boundaries are known as fault lines. Sometimes this grinding is gradual and slow. Often, the edges can catch against each other, which results in force building up along the fault.
The plates keep straining against each other until the forces become too great. The strained edges skid against each other violently releasing the force and causing an earthquake.Coinliker predictions
Divergent boundaries are the second type of boundaries. These are often found on the ocean floor and are called mid-ocean ridges. They look like mountain ranges with trenches in the center when looked at from above. At divergent boundaries, the plates are moving away from each other creating trenches.Rdp hack tool
Underground magma rushes up to fill the gap and rises to the sea floor. There it cools into the stone forming the Earth's crust.
This newly-formed crust slowly moves away from the ridge as the continents drift, and more crust is formed behind it. This is known as seafloor spreading. Convergent boundaries are the third type. At these points, two plates are moving towards each other. One plate is pushed underneath the other and into the ocean of magma under the Earth, where it likely melts into magma over time. The second plate is scrunched as it is pushed on top of the first, and often forms mountain ranges.
The moving of one plate under the other is known as subduction. The theory of plate tectonics was first hypothesized by meteorologist Alfred Wegner inthough he called it continental drift at the time. He noticed that some continents seem to have coastlines which could fit into each other like puzzle pieces.
The east coast of South America and the west coast of Africa are an example of this.
Facts About Pangaea, Ancient Supercontinent
There was also archeological evidence, like the fact that many fossils from the same time-period, and of the same species, were found across South America, Africa, and India. This led Wegner to hypothesize that all the continents on Earth had at one point formed one supercontinent now called Pangeaand had split up over time due to some mysterious force.Teachers Pay Teachers is an online marketplace where teachers buy and sell original educational materials.

Add to cart.About million years ago, scientists believe the seven continents of the world were connected into one supercontinent known as Pangaea. The East coast of South America seems to fit perfectly like a puzzle piece into the Western coast of Africa. And if North America could be slightly rotated, it would comfortably fit next to Europe and Asia. Ancient fossil records show that the same animals and plants once lived along the Eastern coast of South America, as did along the Western coast of Africa.
The same plants and animals also lived along the coasts of Europe and North America. During the millions of years that followed the connection of all the continents, they began to break apart and slowly drift away from one another.
The drift of the continents continues today and in the future, the location of the continents will once again change. The meaning of the word Pangaea comes from the Ancient Greeks and means 'all land'.
The supercontinent existed at the time of the dinosaurs. The crashing together of the continents resulted in the formation of many mountain ranges across the planet. The supercontinent was shaped like a giant letter C, and it spread across the equator and extended from the North to the South Pole, meaning a person could walk from pole to pole without stepping into the ocean.
The formation began about million years ago during the late Cambrian time period and then finished about to million years ago during the Triassic period. Scientists believe Pangaea's climate was much drier and hotter than it is currently.
In the beginning, life did exist, but it was not the same as today. Most of life included single-celled organisms like bacteria. By the time Pangaea completed its formation during the Triassic period, life flourished in the oceans and spread from water to the land.
The first dinosaurs also evolved during the Triassic period, and because there was just one giant piece of land, scientists found the fossils of the same Triassic animals and plants on every continent. The break-up of the continents, as they are today, began during the middle of the Jurassic time period about million years ago. It was at this time when many well-known dinosaurs existed.
The first phase of the Pangaea's break-up resulted into supercontinents Laurasia and Gondwana before each of these large continents eventually broke into the current continents of today and a new ocean was formed, the North Atlantic Ocean. The second phase began when Gondwana separated into Africa, South America, India, Antarctica, and Australia during the Lower Cretaceous period about million years ago.
Finally, the third and final phase of the break-up occurred in the early Cenozoic period. About 60 million years ago.Please download and install the latest version of Adobe Flash Player.
