1. The discharge of a stream is the VOLUME OF WATER FLOWING PAST A GIVEN POINT IN A STREAM

2. In a relatively short period of time, a river has formed a V-shaped valley. Which traits probably characterize the region where the river formed?

SOFT BEDROCK AND A WET CLIMATE

3. What types of bedrock are dissolved most easily by running water?

LIMESTONE AND MARBLE

4. Where is the Western Divide for the Mississippi River System?

IN THE ROCKY MOUNTAINS

5. Under which of the following conditions is a river most likely to deposit

all of its sediments? WHEN THE RIVER FLOWS INTO A LAKE

6. Fertile agricultural areas are characteristic of many of the world’s

FLOOD PLAINS

7. Stream discharge and velocity increase when FLOODING OCCURS

8. A curved body of water that forms when deposits separate a meander

from its river is called a(n) OXBOW LAKE

9. An alluvial fan forms when A STEEP MOUNTAIN STREAM MEETS DRY, LEVEL LAND

10. The part of a river’s valley that is underwater when the river overflows

its banks is called the FLOOD PLAIN

11. All of the land drained by a stream and its tributaries is called a

WATER SHED

12. A large increase in stream velocity is likely to INCREASE THE STREAM’S MUDDY APPEARANCE, DECREASE THE STREAM’S CALM APPEARANCE, AND INCREASE THE STREAM’S ABILITY TO CARRY HEAVIER SEDIMENTS

13. Material a small river carries in suspension includes all of the following

except BOULDERS

14. The bedrock that would erode most quickly in running water is

LIMESTONE-

15. The picture shows the layers in the bank of a river. The differences in

the size of the particles in the layers are most likely caused by differences

in the SPEED OF THE WATER CARRYING THE SEDIMENTS

16. The canyon shown in the picture was most likely formed by

RUNNING WATER

17. Identify the above land forms:

1: ALLUVIAL FAN 2: FLOOD PLAIN 3:DELTA

18. By how much has the length of the delta increased from 1982 to

1996? 4 km (answer is not in word bank)

19. The largest river system in the United States is the MISSISSIPPI RIVER SYSTEM

20. According the above map, the largest river basin in Virginia is the

JAMES RIVER BASIN (answer is not in word bank).

1. List the letters in the sequence that best describes the construction of

a delta from the youngest formation to the oldest formation C A D B (answer is not in word bank)

22. Which type of land cover absorbs the MOST Rainwater?

GRASSLAND (answer not in word bank)

23. Virginia has large deposits of sand and gravel. These are usually found

in areaswhere WATER ONCE FLOWED

24. The higher land that separates one drainage basin from another is called

A DIVIDE

25. The phenomenon whereby a river overflows its banks is called FLOOD

26. All the land that drains into the river either directly or through its

tributaries is called (also called watershed) DRAINAGE BASIN

27. Broad looping bends in a river are called MEANDERS

28. A stream that runs into another stream or river is called TRIBUTARY

29. A river and all of its tributaries is a RIVER SYSTEM

30. The process in which materials are dropped, such as sand or silt

by a stream is DEPOSITION

31. All the land that drains into the river either directly or through its

tributaries (also called a drainage basin) is WATER SHED

32. A fan-shaped deposit that forms when a river flows into a quiet or

large body of water, such as a lake, an ocean, or inland sea is a DELTA

33. Sand, pebbles, and boulders that are moved along the bed of a stream

and are too heavy to be carried in suspension is called BED LOAD
