The temperature at which the motion of particles theoretically ceases is

0K or -273°C

Explanation:

The temperature at which the motion of  particles ceases is 0K or -273°C. At  this temperature the motion of particles is theatrically at rest. This temperature was explained in Charles law

Charles' Law: Charles' Law states that the volume of a given mass of gas is directly proportional to it absolute temperature.

Charles law can be expressed mathematically as

V/T = V'/T'

Where V and V' = Are initial and Final volume respectively, T and T' = Initial and Final Temperature respectively

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
