Question

Explain scientifically how we know that Earth's crust is broken into pieces (plates). (explanations must be multiple sentences)

Answer 1

Answer and Explanation:

Earths crust is broken into plates called tectonic plates.  the plates move bc of  convection currents in the earths mantle.   convection currents are the movement caused with a liquid by the propencity of hotter and less dense matter to rise, and colder, thicker material to sink under the effect of gravitational pull, which as a result results in the transfer of heat.  As a result these are moved by the heat composed by the common natural blight of radioactive component in the earth.
