Question

Fill in the table below to describe the seasonal variation in natural in the Merced River in the Sierra Nevada, the season variation in precipitation and where the water in the stream comes from during each season. Consider only the natural system without human modification. Any answers that consider human modification receive ZERO credit. Which of the following are evidence of past glaciation (ice ages) (circle best answer): (a) granite:(b) volcanic arcs; (c) mid-ocean ridges; U.shaped canyons (e) oceans. The current co2 (carbon dioxide) concentration in the atmosphere is significantly than more that recorded in the geologic record trapped bubbles i e cores) for any of the glacial or interglacial periods within the last several hundred thousand years. True or False (circle best answer)

Explanation / Answer

9)

Precipitation

Winter - 150.5m

Spring – 51.2

Summer – 15.1

Fall- 65.1

Relative amount of water discharge in river

Winter - 200 cubic feet per second

Spring – 2000 cubic feet per second

Summer – 3500 cubic feet per second

Fall- 50 cubic feet per second

10) d) U-Shaped valleys

Erosional and depositional features are examples of past glaciation. Erosional features are ice scoured U-shaped valleys, cirques, horns, aretes and truncated spurs; and depositional features are  drumlins, end moraines, lateral moraines, flutes, protalus ramparts, erratics, and dropstones.

11) True. The current CO2 levels in the atmosphere is significantly more than than recorded in the past.
