A narrow valley is a V-shaped valley, or river valley. A narrow valley has steep sloped sides that look like the letter V. They are formed by a strong stream.
There are more than one term for a deep narrow valley. Glens, canyons, ravines, fjords are terms you could use.
The different types of river valleys include V-shaped valleys, U-shaped valleys, and canyon valleys. V-shaped valleys are typically narrow with steep sides, carved by erosion from a river. U-shaped valleys are wider and have more gradual slopes, formed by glaciers. Canyon valleys are deep and narrow with steep sides, often formed by a combination of tectonic activity and erosion.
The stream valleys associated with plateaus are often deep and narrow, with steep sides. These valleys are typically created by the erosive force of rivers cutting through the plateau over time. They can provide important routes for water drainage and transportation through the plateau region.
Ravines are deep, narrow valleys with steep sides, typically formed by the erosion of fast-flowing water like a river or stream. They can vary in size and are often characterized by their rugged terrain and unique ecosystems. Ravines play important ecological roles by providing habitat for a variety of plant and animal species.
A deep valley with steep sides would be called a gorge or canyon.
The term used for narrow deep valleys is "ravine."

The deep narrow valleys on the Moon are called rilles. These are long, winding depressions that can stretch for many kilometers across the lunar surface. Rilles are thought to have been formed by a combination of ancient volcanic activity and tectonic forces.
The different types of river valleys include V-shaped valleys, U-shaped valleys, and canyon valleys. V-shaped valleys are typically narrow with steep sides, carved by erosion from a river. U-shaped valleys are wider and have more gradual slopes, formed by glaciers. Canyon valleys are deep and narrow with steep sides, often formed by a combination of tectonic activity and erosion.
Deep V-shaped valleys are commonly known as river valleys and are formed by the erosive action of flowing water over time. These valleys typically have steep sides and a narrow bottom, shaped by the continuous erosion of the river cutting through the land.
