Describe the motion of the molecules in the cold water in terms of their kinetic energy.

As ice melts into water kinetic energy is being added to the particles.This causes them to be "excited" and they break the bonds that hold them together as a solid resulting in a change of state:solid -> liquid.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

i would say it is
