Document Content and Description Below

• Question 1 2 out of 2 points Drought in California: The ___________ is a better index for determining drought conditions in an area, because ___________________. Palmer Hydrological Drough ... t Index (PHDI), it looks at the cumulative moisture conditions over many months Palmer Hydrological Drought Index (PHDI), it looks at the cumulative moisture conditions over many months ! You want to look at the PHDI because it reports the moisture conditions over many months. If you have 12 month of drought followed by 1 month with above normal precipitation, this is not enough moisture to recharge soils, plants and aquifers in an a region. • Question 2 2 out of 2 points Pre-lab Exercises: What type of interaction is described by the following? Animals drink water from a stream. hydrosphere-biosphere interconnection hydrosphere-biosphere interconnection • Question 3 0 out of 2 points Drought in the Heartland, Soil Moisture Profiles Question a: The soil moisture during the summer of 2012 in central Illinois (where the arrow is pointing in the assignment) was higher than normal. True Fals e No, it was significantly lower than normal. • Question 4 0 out of 2 points Drought in the Heartland: Temperature questions, The areas near the intersection of the California, Arizona and Nevada border (extreme southern area within the southwestern U.S.) experienced a cooler month than "normal" during July 2012. Fals e True The blue part of the Temperature Anomaly plot over these areas, and the negative numbers, indicate that the temperature was cooler than the normal temperatures for the month of July. • Question 5 2 out of 2 points Pre-lab Exercises: What type of interaction is described by the following? Rainwater infiltrates and recharges the soil. pedosphere-atmosphere interconnection pedosphere-atmosphere interconnection • Question 6 0 out of 2 points Drought in the Heartland, Soil moisture questions: Most of Arizona was suffering from lower than normal soil moisture levels in July 2012. Fals e True This is true. If you look at the soil moisture anomalies chart, most of Arizona had an anomoly (diversion from "normal") of -20 mm up to -40 mm. • Question 7 2 out of 2 points Drought in the Heartland, Soil moisture profiles over time: The soil moisture levels increase during the winter and spring months, in general. Tru e Tru e This is true, because temperatures are lower (less evaporation) and so "spring showers" can be used to recharge soil systems. • Question 8 2 out of 2 points Drought in the Heartland, Evaporation profiles questions: Arizona and the desert Southwest experienced the highest evaporation rates during July 2012 in the U.S. Fals e Fals e Nope, this is false! This part of the country has less moisture on the surface and in the soils to begin with, so there is less water available to evaporate. • Question 9 2 out of 2 points Drought in the Heartland, Evaporation profiles questions, The evaporation values in this plot are describing the movement of water from _______ to ________. Select the answer that completes this statement. FROM the hydrosphere and litho/pedosphere TO THE atmosphere FROM the hydrosphere and litho/pedosphere TO THE atmosphere • Question 10 2 out of 2 points Drought in California: According to the national PHDI map, the state of ____________ is also experiencing an extreme drought in March 2015. Nevad a Nevad a Nevada is also in an extreme [Show More]
