A glacier is a vast body of frozen water that flows downhill, like a river. There’s one important difference though—glaciers move sooooo slooooowly that you could sit and stare at one for ages, and not spot any change.
When a glacier moves, its great weight melts the ice at its bottom, so it actually glides along on a thin fi lm of water, like an ice skater. These rivers of ice are big and tough. Glaciers grind away at rocks, creating U-shaped valleys and collecting a heavy load of rocks and pebbles. When a glacier melts, piles of pebbles might be one of the few signs that it ever existed!
