a.) Using Earth's estimated cratering rate of Ncum (D > 22.6 km) = 1.8 x 10-15 craters/km2/yr, and a power law exponent b = 1.8 (see your class notes), compute the size of the largest crater likely to have formed in Sweden (area = 450,000 km2) since the formation of its surface rocks -2000 Myr ago. How does this compare to the size of the putative Uppland structure? b.) Calculate the probability that a crater as large as Uppland would have formed in the past 2000 Myr. Note that the largest confirmed crater in Sweden is the 55 km-diameter Siljan structure.

If the aquifer is 50 m thick, how much water (m²) would the aquifer produce if the piezometric surface is lowered by 50 m over an area of 50 km²? b. A confined aquifer has a source of recharge as shown in Figure below. The hydraulic conductivity of the aquifer is 100 m/d and its porosity is 0.35.
