PLEASE I BEG YOU SO MUCH 15 POINTS HELP ME 4. Armando thinks that it is the very steep hill that makes this river narrow and deep, but his classmate thinks it is the small size of the sand grains that the water flows through.

What information can the model provide us that would be used as evidence that Armando's idea is correct?

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
