what is the difference between a valley and a canyon?
canyons are eroded by streams; valleys are eroded by glaciers.
nothing, the terms are synonymous.
the sides of a canyon are steeper than the sides of a valley.
the sides of a valley are steeper than the sides of a canyon.

Explanation:

Valleys can be formed by various processes (including glacial and fluvial), while canyons are typically associated with more intense erosion (often by rivers). But the key differentiating physical characteristic is the steepness of the sides. Canyons have steeper sides compared to valleys. The first option is incorrect as valleys can also be eroded by streams. The second option is wrong as they are not synonyms. The fourth option is the opposite of the correct relationship.

Answer:

The sides of a canyon are steeper than the sides of a valley.
