What is the energy of an object in motion? ?

The energy of an object in motion is kinetic energy. 

Kinetic energy comes from potential energy, which is the energy stored in an object due to its location relative to the Earth(gravity, etc.).

Magma forms by partial melting of upper mantle and crust. partial melt means that only a fraction of the available material forms a melt, and that the remainder stays solid. the partial melt rises because of its lower density and ascends through he crust. this is so conclusive mean the answer would be magma igneous rocks or balistic magma.
