Hurricanes don't make rivers so B definetley isn't the correct answer. A collapsed volcanic caldera has legit nothing to do with rivers so thats a no for C. and that leaves A and D and if you poor like 100 whole jugs of water into soil its not going to create a river which leaves B as the only answer that makes sense.

When you're climbing a mountain, the temperature decreases (it gets colder), at least in the first layer of the atmosphere, which is called troposphere.

So in short, the temperature decreases continuously the higher you reach the mountain.
