Plate Tectonics

The theory of plate tectonics describes the motions that happen in the earth's lithosphere.These motions cause to create the mountains, oceanic trench, volcanic activity, eartquake...etc.Mainly in our earth lithosphere,there are 6 siz main plates.

1. Eurasian Plate
2. North American Plate
3. South American Plate                     
4. Indo-Australian Plate
5. African Plate
6. Pacific Plate

Instead of these six plates,there are small plates such as Caribbean Plate,Cocos Plate,Filipino Plate,Arabian Plate etc.Nowadays,the scientists have found that a new plate is creating in Indo-Australian Plate.

Among these plates,we can recognize three kinds of plates.

1. Transform Boundaries
2. Divergent Boundaries
3. Convergent Boundaries

Many scientists have found that these plates move each and every year,but we do not feel it.They have also provided the evidences to prove it.

When two plates meet together,a pressure creates among the two plates and causes to create montains.For instances we cam mention the mountains such as Himalaya.The opposite of this activity causes to create an oceanic ridge.For instance,we can mention Mid-ocean ridge.

Through above image the changes have been showed.Earlier the African plate was located near the South American plate,but with the time it has moved near to Eurasian Plate.In costal areas,same species of plants and animals also have been found.

As I described above the changes of plates cause to create mountains,oceanic trench,volcanic activities and even Tsunami.
