1. The diagram shows a coastal region in which the land slopes toward the ocean. Point X is near the top of the hill, point Y is at the base of the hill, and point Z is a location at sea level. This stream is not shown in the diagram.
Which diagram best shows the most probable path of the stream flowing from point X to point Z?

2. This is a RIVER SYSTEM.

3. Where does EROSION dominate?
WHY?
WHY?
Where is DEPOSITION dominant?

4. Diagrams A, B, and C represent three stages in the development of a river valley.
Which is the correct order of evolution of this system from youngest to oldest?
B  C  A

5. Diagrams A, B, and C represent three stages in the development of a river valley.
Which bar graph correctly represents the average gradients of the rivers as shown?

6. What causes this to occur?
Diagrams A, B, and C represent three stages in the development of a river valley.
The diagram below indicates what occurs when this river reaches the lake it feeds into.
What causes this to occur?
The water slows down
(and sediments deposit from largest to smallest!)

7. The VOLUME of water in a river is related to the water cycle
The VOLUME of water in a river is related to the water cycle. It is also connected to ground conditions. A change to any can vary the VOLUME of water.

8. Water that infiltrates (enters) the ground is called groundwater.
Groundwater rises to a level called the Water Table.
(Saturated zone)

9. Well

11. Run off
(Saturated zone)
If the ground is impermeable (if water cannot infiltrate) it will run off the surface.
More permeable = more Infiltration = less runoff
More impermeable= less Infiltration = more runoff

12. Sometimes the ground is impermeable to water if it is already saturated.

13. Sometimes the ground is impermeable to water if it is already saturated.

14. Which will add more water to a nearby river?
Sometimes the ground is impermeable to water if the gradient is too steep.
Which will add more water to a nearby river?

15. Which looks like it has more space (porosity) for water?
Sometimes the ground is impermeable if the soil is not very porous.
Which looks like it has more space (porosity) for water?

16. Which process is represented by letter F?
(1) capillarity (3) runoff
(2) infiltration (4) freezing
What does letter X represent?
(1) the water table (3) sea level
(2) a floodplain (4) impermeable rock

17. If the surface soil is saturated and precipitation increases, there will be
(1) a decrease in the amount of groundwater
(2) an increase in the rate of capillarity
(3) a decrease in the surface elevation of the lake
(4) an increase in the amount of runoff
