Which is the correct sequence in the formation of a glacier? snow, firn, granular ice, glacial ice?

The correct sequence in the formation of a glacier is snow, granular ice, firn, glacial ice. 
Glacier is a large mass of ice on land that shows evidence of being in motion, or of once having moved under the force of gravity. Continental glacier is a thick, slow-moving sheet of ice that covers a large part of a continent or other large landmass. A valley glacier is a river of ice that forms in the cold heights of a mountain range, where snow accumulates, then moves downslope, either flowing down an existing stream valley or carving out new valley.
