CHAPTER 10: GROUNDWATER
Section 10.1 Movement and Storage of Groudwater
1. Create a pie graph that compares the percentages of the sources of water on Earth.
2. Sequence Number the steps in the movement of ground water. The first one has been
completed for you.
_____ water infiltrated into the ground
__1__ seawater evaporates
_____ water becomes part of groundwater
_____ precipitation
_____ groundwater returns to surface through springs
_____ water flows from springs back to the oceans
3. Draw diagrams of sediment with different porosity.
Well-Sorted Sediment
Poorly Sorted Sediment
Hypothesize why poorly sorted sediments might be less porous.

and the water table.

5. Draw a diagram similar to Figure 10.3 with an aquifer overlain by an impermeable
layer of rock.
-Show where a reliable well could be dug.
-Draw a well that would be unreliably filled with water.
-Show where a well would be dry.
Section 10.2 Groundwater Erosion and Deposition
1. Analyze cave formation by completing the paragraph below.
A ______________ is a natural underground opening with a _______________ to the
surface. Caves form when ______________ is dissolved by ________________. The
limestone becomes more ________________ as it dissolves. Caves usually form in the
zone of _____________________ below the ______________________.
2. Draw a diagram to show the landforms found in a karst region. Label the following
on your diagram:
- dry cave -sinkhole -sinking stream -water-filled cave -water table

3. Create a Venn diagram to compare and contrast stalagmites and stalactites.
Section 10.3 Groundwater Wells
1. Draw a diagram illustrating how an artesian well forms.
2. Describe how pumping affects a water well by completing the cycle diagram below.
Water level in a well is the
same as the water table.
Water supply is
Well is ____________

and runoff.
A _____________ of
_______________ is created.

controlled.
