Question

How does tectonic plate movement change the earth?

Answer 1

Hint: Plate tectonic refers to the theory in which the outer shell of the Earth is divided into few plates that glide over the mantle which is the rocky layer of inner side above the core area. It acts like a hard shell if compared to the mantle of the Earth.

Complete answer:
The surface of the Earth is in constant change. There are 15-20 tectonic moving plates in the lithosphere.The tectonic plates are like pieces of cracked shells on the mantle of the Earth. The mantle is hot. The heat due to the radioactive process that takes place in the interior surface of the Earth causes the movement of the plates.

Tectonic plates are always in the continuous movement though the movement is not felt by us. This movement eventually led to change on Earth. These move sometimes towards each other and sometimes away, this movement is referred to as tectonic shift.Cracks in the surface of the Earth are formed sometimes by this movement. The continents move slowly but sometimes this movement can lead to breaking them apart. It takes millions of years for such action to take place.Volcanoes are created due to the tectonic plates movement. The two plates move and they hit each other, one is slowly pushed beneath the other one. Molten rock wells up and erupts from volcanoes. This creates volcanoes. Due to the tectonic plates movement the Pangaea which existed 250 million years ago broke into different continents.

Note:The surface of the Earth is in constant change. The lithosphere consists of about 15-20 tectonic moving plates. The tectonic plates are like pieces of cracked shells on the mantle of the Earth. The mantle is hot. The heat due to the radioactive process that takes place in the interior surface of the Earth causes the movement of the plates.
