Avalley is noticeably lower than the surrounding area. what is one way a valley might form?

Through erosion by wind and water

Explanation:

A valley is a depression on earth’s surface that is usually occupied by any water body either a river or a stream.  

Due to running water and sometimes even wind, there occurs gradual wearing of land mass which ultimately leads to formation of valleys. The shape and size of the valleys is very much defined by the force which is causing its erosion, the rock characteristics and the slope of the land.  

Hence, there are three types of valleys – a) U-shaped valleys b) V-shaped valleys and c)  flat-floored valleys.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."

i think the answer is 95 hope this
