Answer:
The correct descriptions of tectonic plates are:
B) Move very slowly
C) Move over the layer of Earth’s mantle
D) Can crush together to make mountains
Step-by-step explanation:
Tectonic plates are pieces of the Earth's crust that move due to the heat produced by the mantle. They are not very large, usually only a few hundred kilometers across. These plates can move apart, collide, or slide past one another along fault lines. As they move, they cause earthquakes, volcanoes, and the formation of mountains.
Tectonic plates move very slowly, at a rate of a few centimeters per year. The movement of tectonic plates over the Earth's mantle is driven by the heat generated by the mantle itself. When two tectonic plates collide, the edges of the plates can be forced upward, creating mountains. Therefore, it is true that tectonic plates can crush together to make mountains.
hope this helps good luck on the quiz! <3
