What is the definition of valley widening?
Because the stream gradient is moderate or low, the river begins to erode the bank of its channel instead of valley walls. This eventually leads to a meandering stream across a valley floor. Over time, the stream continues to meander and erode the valley’s soil, widening it further.
What is a valley shaped like?
They all take the form of a “U” or “V.” Rivers and streams make most primary valley cuts, carving steep-walled sides and a narrow floor that from afar looks like the letter “V.” The gradient of the river—how quickly it drops—helps define the steepness of the sides and the width of the floor.

Such valleys can be up to 100 km (62 mi) long, 4 km (2.5 mi) wide, and 400 m (1,300 ft) deep (its depth may vary along its length). Tunnel valleys were formed by subglacial water erosion.
