Answer to Question 1

Answer: After chemical and mechanical weathering break down rock, water picks it up and carries it away (erosion) in the stream current. When the stream current decreases speed, it can no longer carry the heavier material, so it drops its load (deposition).

Answer to Question 2

Answer: Sial is less dense than sima, and the continents lie at a higher elevation as a result.
