___ influences the velocity of a river along with gradient.
A) Direction of flow
B) Channel shape and roughness
C) Temperature of the water
D) Chemistry of the water
E) Latitude of the river

Question

Quizplus · Accepted Answer

Channel shape and roughness refer to the physical characteristics of the riverbed and banks, including the size and shape of rocks and other obstacles that can cause friction and turbulence in the water. These factors can slow down or speed up the flow of the river, affecting its velocity in combination with the gradient or slope of the river. The other choices, such as direction of flow or water chemistry, may have other effects on the river but do not directly influence its velocity. Latitude may have some indirect effects on river velocity, such as if it affects the amount of precipitation and runoff contributing to the river, but this is not a direct factor influencing velocity. Temperature of the water may affect the density and viscosity of the water, but its effect on river velocity is generally considered to be negligible compared to other factors.
