The velocity of groundwater flow can be described by the following equation vi where i is the hydraulic gradient, given by h2-h and hi and h2 are the heads at locations 1 and 2 (head is a measure of total mechanical energy of a parcel of groundwater, and is measured in units of length) and l is the distance between the two locations. k is a property of the medium and water called the hydraulic conductivity (units of l/t), and n is a property of the medium called the porosity (dimensionless). how many feet will groundwater travel in one year given the following parameters? make sure your answer has the correct number of significant figures! h2(ft) 345.2 h1(ft) 344.5 l(ft) 915 k(m/d) 7.7 n 0.16

d. i., ii., iii., and iv.

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.

the answer is c i just put d and i got it wrong so yeah its d
