20 Back to Board B. Area of land that features streams that flow into the Yuba River

21  A. darker, warmer, A. darker, warmer, More organisms  C. darker, colder, C. darker, colder, Higher pressure, Fewer organisms  B. doesn’t change in B. doesn’t change in in a pattern  D. darker, warmer, D. darker, warmer, Lower pressure, More organisms How does the ocean change with increasing depth?

22 Back to Board C. It gets darker, colder, pressure increases and it contains fewer organisms.

34 Back to Board D. small

35  A. as it slows, large A. as it slows, large sediment is deposited Why do you typically find bigger rocks along the banks of a fast-moving stream and smaller rocks beside a slower-moving stream?  B. as it slows, small B. as it slows, small sediment is deposited  D. slow carries D. slow carries dissolved sediment only  C. fast carries large C. fast carries large sediment only

36 A. As a stream slows, it deposits its larger sediments first
