PASSAGE
A river flows 200 kilometers from its source in the mountains (elevation 1500 m) to the point where it enters a large plain (elevation 500 m). Over the next 400 kilometers across the plain, it flows to its mouth at sea level (elevation 0 m).
Based on the information provided, how do the river's gradient and dominant fluvial processes likely change as it moves from the mountain section to the plain section?
