Respuesta :
Answer:
A is the correct Ans
Explanation:
B C D options cannot explain why each river has its own set of characteristics.
Answer:
I think the answer is B) "Rivers interact with the ecosystems through which they pass."
Explanation:
A, doesn't make sense to me, because maybe gravity does effect the river in some way, but it didn't really explain why or how.
C, also doesn't make sense, because I fail to see what characteristics would change, other than the color maybe. And even if the color does change, I'm guessing it would have to be a significant change in oxygen.
D, is not it either, because climate refers to weather not rivers.
Hope this makes sense :) Also if I'm correct could you mark me brainliest please?
