Tectonic plates are present on the earth's surface because the lithosphere is weak and cracked in several places the core is so hot that it created cracks in the crust the hot asthenosphere created cracks in the lithosphere the earth was originally formed with cracks in its lithosphere

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.

An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to move.
