Question
Chapter 19, Problem 1LC
To determine
The similarities and differences of highland ice fields and continental ice sheets.
Expert Solution & Answer
Answer to Problem 1LC
Both highland ice fields and continental ice sheets are continuous covers of glacial ice; The difference between them are that the highland ice fields are found only in high-elevated mountain regions, and are much smaller in surface area than continental ice sheets. The continental ice sheets are several meters deep and wide that develop over the non-mountainous areas of the continents such as Greenland and Antarctica.
Explanation of Solution
Highland ice field:
A highland icefield is an unconfined ice sheet accumulation in a high-mountainous region that extends a few hundred or few thousand square kilometers. It encloses all the underlying topography except for some protruding pinnacles called “nunataks”. These highland icefields are significant in portion of the high country of western Canada and southern Alaska and on various islands of the Arctic, specifically Iceland.
Continental ice sheets:
A massive blanket of ice that completely engulfs the landmass underneath to about hundreds or thousands of meters depth. The depth of the ice sheets are greater in its interior and thins out at the outer edges. These are formed in non-mountainous areas of continents. There are only two true ice sheets currently, in Antarctica and Greenland.

D) discontinuous permafrost
Use the attached piezometer map to make your own, clean version of the map, and indicate the elevation of the water table at all piezometer locations.
Draw equipotential lines (lines of equal water table elevation) using regular intervals – creating a contoured map of the water table.
Determine the direction of groundwater flow based on the horizontal gradient. Label the areas of recharge and discharge directly on your map.
Flow lines: Draw flow lines on your water table map. The lines should be at right angles to the equipotential lines and extend from the recharge area to the discharge area.
Hydraulic Gradient, Specific Discharge (Darcy Flux), Average Linear Velocity:
Using your water table map, estimate an average hydraulic gradient between two locations, call them locations A and B, one at the eastern-most and a second at the western-most extent of your dataset (note the north arrow on the map).
Calculate the specific discharge, q, between the two locations. For this calculation…

Q in (L/day)
Q out (L/day)
Residence time (days)
