Answer:
Armando's idea is correct.
Explanation:
Armando's idea is correct because water usually flows through the hills which is very steep and sloppy. The river that flows in the hill makes the hill narrow and deep due to the removal of rock particles which comes in the way of river. This is not the small sized sand grains that the water flows through because in the hill water flows through rock particles not sand grains.
Armando thinking that it is the very steep hill that makes this river narrow and deep is the ( correct conclusion )
When water flows through a hill some particles of the hill is washed away by the heavy flow of water ( usually flood water ) into the river. the pressure with which the water flowing through the hill enters the river will determine the river depth and also the narrowness of the river.
The size of the sand grains in the river does not determine the narrowness or depth of the river but the pressure which the water enters the river from the steep hill determine these characteristics.
Hence we can conclude that Armando's conclusion is correct.
