Question

decribe theory of plate tectonics

Answer 1

From the deepest ocean trench to the tallest mountain, plate tectonics explains the features and movement of Earth's surface in the present and the past. Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core

Plates interact at three types of plate boundaries: divergent, convergent and transform. Most of the Earth's geologic activity takes place at plate boundaries. At a divergent boundary, volcanic activity produces a mid ocean ridge and small earthquakes.

$\huge \red {\boxed {\boxed {\mathbb {QUESTION}}}}$

what are tectonic plates.?

$\huge \purple {\boxed {\boxed {\mathbb {ANSWER}}}}$

$\huge \blue {\underline {\underline {\mathbb {TECTONIC\:PLATES}}}}$

⚫The lithosphere is broken up into plates called as tectonic plates.

⚫On Earth, there are seven or eight major plates and many minor plates.

⚫the shaking or colliding of these tectonic plates causes earthquakes and volcanoes.

$\huge \pink {\boxed {\boxed {\mathbb {EXPLAINATION}}}}$

=> Tectonic Plates are the plates on which the continents stands.

=> There are 7 major tectonic plates and there are many minor tectonic plates also.

=> The tectonic plates are the large pieces of rock under the earths surface .

=> that are constantly moving and responsible for causing earthquakes and volcanic eruption.

=> Tectonic plates refer to the small bit of layers of earth's crust and topmost layer of mantle.

=> These plates are main cause of mountain formation, volcanoes and tsunamis.

=> A tectonic plate is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere.
