Explain how Convection currents in the Earth’s mantle cause tectonic plates to move. Use the terms gravity and thermal energy in your answer.

Umm well ,The currents that cause the movement of the tectonic plates that make up the earth's crust as magma is a rock which is below the crust in the mantle and tremendous heat and pressure within the earth cause the hot magma to move in convection currentts.

I hope it helps

have a great day

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).
