what are tectonic plates ? class 9 geography
Answers
Answer:
If we talk about the Tectonic plates then Tectonic plates are the big pieces of the Earth's crust and upper most mantle. Now in the explanation part we will se in details about the tectonic plates.
Explanation:
Tectonic plates are the big pieces of the Earth's crust and upper most mantle and if we talk about it's formation so it is formed by oceanic crust and continental crust. When the earthquake occurred in the ocean then the edges of the plates are marked. There are seven tectonic plates present in our atlas which we known as Continents and the name of continents are Africa, Australia, Antarctica, Asia, Europe, North America and South America. Mountains are also formed because of these tectonic plates.

Answer:
Explanation:
Tectonic plates.
According to the idea of plate tectonics,
Earth's crust is divided into a number of plates that move across the mantle, the rocky inner layer above the core. Unlike Earth's mantle, the plates behave like a solid, rigid shell. The lithosphere is the name of this robust outer layer.
Seven to eight large plates, as well as several smaller ones, make up the lithosphere of the globe. Tectonic plates are fragmented inside the lithosphere, the earth's hard outermost shell. The kind of boundary, such as convergent, divergent, or transform, is determined by the relative speed of these plates when they collide.
Along these plate borders, volcanoes erupt, earthquakes cause mountains to develop, and oceanic trenches to form. Between zero to one hundred millimetres each year, on average, the plates' relative movement varies.
