  The Earth’s surfaceis made up of large plates. These plates are known as the Tectonic plates. The tectonic plates do not stay fixed at one position but instead they are in constant movement. What are Tectonic plates?

  As I havementioned before, Tectonic plates have the ability to move. But they do so only by few centimeters each year. They can move due to convention currents. We can say that the Tectonic plates move because if you look at a map of the world carefully, you will notice that each continent can fit together nicely. The land mass was then called a Pangea.

  The idea ofTectonic plates moving together or apart is known as a Continental drift. This theory was first being invented by a German scientist called Alfred Wenger. The Continental Drift

  The different Tectonicplates

  When two Tectonicplates come together, they are actually being pushed against each other. When this happens, the boundaries of each plate move upwards as it has no where else to move. This action causes a mountain range to form. What happens when Tectonic plates move together

  When a Tectonicplate moves apart from another one, water starts to collect in between the two plates. As the water starts collecting, an ocean is actually being formed. We can say that the two plates are diverging . What happens when a Tectonic plate move apart

  Long time ago,India was not connected to Asia, but was on its on. Then, one day the plate started moving little by little towards Asia until one day, it crashed into Asia. This connection caused the boundaries of each plate to hit and move upwards, which caused the formation of the Himalayas. Example of Tectonic plates moving together

  An example weretwo plates moved apart was when the Atlantic ocean was created. Two tectonic plates had moved apart. This lead to formation of water in between the two plates. As the two plates moved further apart, more and more water was accumulated in between. Examples of Tectonic plates moving apart

  Tectonic movement cancause serious catastrophes. It can result in Volcanic eruption, Tsunamis and finally earthquakes. A volcanic eruption is caused when two Tectonic plates move apart . An earthquake is formed when two plates hit together and finally, a Tsunami is formed when an earthquake has taken place. Disadvantages of movement of Tectonic Plates

  Example of arecent Tectonic movement A recent case of movement of Tectonic plates was in 2004. The Eurasian plate had moved, causing an Earthquake at Sumatra. And this did not stop there. The Earthquake had formed gigantic waves, called Tsunami . The tsunami did a lot of damage to most of the countries of the Asian coast, especially India, Sri Lanka, Indonesia and Thailand. Tsunami

  I will concludeby saying that Tectonic Plates play an important part in the development of our planet cause it may cause a lot of damage if it moves. My Conclusion
