Tectonic activity happens when changes to the Earth's crust are caused by . A. changes to the Earth's gravity B. changes to the Earth's temperature C. the movement of the Earth's plates D. the rising of the Earth's oceans Please select the best answer from the choices provided A B C D

C. the movement of the Earth's plates

Explanation:

The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth's mantle and fit snugly against one another. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other.This movement is called plate motion, or tectonic shift.

because the two particles have an equal charge, the charges will cancel out and give the atom an overall charge of 0. so, if at atom has 35 protons in the nucleus, we could expect it to have 35 electrons orbiting that nucleus.
