Question

17. The discharge of a bank full stream 10ft wide and Sft deep with a velocity of 4ft/sec is: a) 500cfs b) 150cfs c) 200cfs d) 50cfs (cfs-cubic feet per second) 18. The place where you should expect to find the lowest rates of physical weathering: a) Alaska c) Montana mountains d) Sahara Desert e) Iceland b) Vermont 19. Geologists study sedimentary rocks to determine the: a) composition of the source rocks b) sequence of paleo-events c) paleo-climate d) depositional environment e) all of these note: paleo-old 20. The sediment deposited in the ocean just beyond the visible part of the Mississippi river delta is mostly: a) cobbles b) sand e) limestone c) mud d) salts

Explanation / Answer

17. The discharge of the bank= velocity x area

There fore the discharge of the bank= (10 x 5) x (4) = 200 cfs (cubic feet per second)

18. Physical weathering is more prominent in Sahara deserts. Because physical weathering is more pronounced in hot and dry climatic regions.

19. Geologists study the sedimentary rocks to determine all of the above.

20. The sediment deposited in the ocean just beyond the visible part of Missisippi river delta is mostly mud
