Gradient is an area of ground that tends evenly upward or downward.
A stream gradient can be defined as an area of water that that tends evenly upward or downward of the stream and it is measured by the difference in elevation between two points on a stream divided by the distance between the two points that the water actually flows.
The gradient influences the speed in respect to time of the stream. The steeper the gradient, the higher will be the speed of the of the flow.
Answer: adjacent to the rivers

Internal migration or domestic migration is human migration within one rural to urban areas, in a process described as urbanization, has also produced a form of internal migration .
Answer: Adaptive Speciation
Explanation:
The two species evolved as s result of adaptive Speciation.
Adaptive speciation occurs when biological interactions induce disruptive selection and the evolution of assortative mating, thus triggering the splitting
understanding processes of adaptive speciation, in which the splitting of lineages is an adaptation caused by frequency-dependent selection. Adaptive, or sympatric, speciation has been modeled since the 1960s.
