How were the tectonic plates formed?

Answer 1

Tectonic plates are formed when a new crust is created ,it forms what looks like giant plates. One side of the plate is where new crust is being made, while the other side is where older crust is being destroyed.These plates only move from 5-10 cm a year.

Answer 2

When 2 plates move away from one another (as in the case of a constructive plate boundary), magma from the underlying mantle rises to the surface where it cools and solidifies along the fault. At times, fissures along the plate boundary/fault lines allow the magma to continue rising upwards and cool on the plate surface, forming layers of rock which heap onto one another, eventually resulting in the formation of a volcano over time. The shape of the volcano slope is determined by the viscosity of the lava which emerges from the mantle beneath the crust.

Answer 3

tectonic plates don't form at plate boundaries plate boundaries are the ends of tectonic plates

Answer 4

Land moves in diffrent directions, land is pulled up and in other places pulled down.

Answer 5

because the magama beneath makes a crack on the plates

Answer 6

At the places where the tectonic plates crack, the hot lava erupts out and when it cools, it forms rocks.

Answer 7

they create landforms and earthquakes by smashing into eachother an example of this is the himilayas

Answer 8

they form the 7 continents in this case.
