Selecting the lucky competitor
Rules: We will do this in quarterfinals,
semifinals, and final round. So I need 8
volunteers.
Face away from the screen. I will read the
question. The first to stand up gets the first
guess.
Selecting the lucky competitor
Lightning Round Quaterfinals 1: What type of a
load dominates a stream that looks muddy?
Selecting the lucky competitor
Lightning Round Quaterfinals 2: In an
impermeable landscape, you would expect to see
what type of stream flow?
Selecting the lucky competitor
Lightning Round Quaterfinals 3: What is loess?
Selecting the lucky competitor
Lightning Round Quaterfinals 4: when
accumulation > ablation, what would happen to
the snout of the glacier?
Selecting the lucky competitor
Lightning Round Semifinals 1: Oxbow lakes
indicate what happened?
Selecting the lucky competitor
Lightning Round Semifinal 2: How can sorting
be used to distinguish a debris-flow deposit from
a stream flood?
Selecting the lucky competitor
Lightning Round Final:
Locate the Sahel on the globe

You buy a house next to a stream that
has a width of 5 feet, a depth at the top
of its bank of 10 feet deep. You need to
calculate the velocity needed for the
stream to have a discharge of 200
ft3/sec. The velocity would be
50:50
A: 2 ft/sec
B: 40 ft/sec
C: 4 ft/sec
D: 4 ft2/sec

Qualifying Answers: suspended load dominates a muddy stream;
ephemeral flow occurs in impermeable landscapes; loess is a
deposit of dust; when accumulation is greater (>) than ablation,
the snout of a glacier moves forward; oxbow lakes indicate that a
stream had an avulsion; sorting separates different particle sizes,
and this is done by streams, not mass wasting events
