Explain the cause of the spring and fall overturns that occur in large lakes.

Explain what leads to thermal stratification in temperate lakes.

Why would nitrogen in the runoff increase so drastically with deforestation?

Temperate Semiarid Arid % mm % mm % mm Total precipitation 100 500-1,500 100 200-500 100 0-200 Surface evaporation 33 160-500 50 100-250 70 0-140 Groundwater recharge 34 160-500 20 40-100 0-2 Surface runoff 33 160-500 30 60-150 29 0-60 Data courtesy of Prof. François Zwahlen, Hydrogeology Center, University of Neuchâtel, Switzerland. The amounts of evaporation, groundwater recharge, and surface runoff differ among the different climate regions. Referring to the percentages given in the table, use the following dropdown menus to rank the variability of each component, from lowest to highest. Surface runoff < Groundwater recharge ▼ < Surface runoff Given these data, you can conclude that freshwater from precipitation is distributed unevenly v in the world. Which climate region will likely suffer the least with increasing freshwater shortages? O Arid regions O Semiarid regions O Temperate regions
