Question

when glacier cut their way through mountains, they form which type of valley's​

Answer 1

HERE'S YOUR ANSWER

As the glaciers ooze, they pick up rocks and grind away at the valley floor and sides, pressing the "V" into a "U." When the glacier melts, a U-shaped valley marks the spot where the snow and ice once flowed. Side valleys are formed by tributaries to streams and rivers and feed the main stem.
