Chapter 11 Science Study Guide
1) A stream is most likely to deposit the rock and soil that it is carrying when IT’S CURRENT SLOWS.
2) Old rivers are characterized by SEDIMENT DEPOSITION
3) If a stream has a high discharge rate, it CAN CARRY LARGER PARTICLES.
4) An aquifer allows THE FLOW AND STORAGE OF GROUND WATER
5) The area of land drained by a river system is the WATERSHED
6) A layer of _SEDIMENT_________________ is deposited on the land that is flooded.
7) An increased amount of water in a given time increases a streams DISCHARGE.
8) Materials that a stream carries in its water are called its LOAD
9) The action of a streams load that cuts through rock and soil is called EROSION
10) The natural barrier that helps keep a river inside its banks is called LEVEE
11) Runoff that contains fertilizer and pesticides and flows from neighborhood yards into street gutters is WATER
POLLUTION
12) The boundary between the aquifer and surface soil is called the WATER TABLE
13) Where the Nile River flows into the Mediterranean, a fertile _DELTA_______________ has fomed.
14) Energy from the sun drives the continuous movement of water in the WATER CYCLE
15) Flooding causes destruction, but it can also create rich soil in an area called FLOOD PLAIN
16) A fast-flowing mountain stream is likely to have a high GRADIENT
17) The rock layer that stores groundwater and allows the water to flow is AQUIFER
18) When more water is pumped out of an aquifer than is replaced by rain is OVERDRAFT
19) The upper surface of underground water is WATER TABLE
20) Water found in rocks below Earth’s surface is GROUNDWATER
21) Besides gradient and load, what else affects stream erosion? DISCHARGE
22) What are the deposits of rock and soil by streams? SEDIMENT
23) Besides deltas and floodplains, what is another type of stream deposit? ALLUVIAL FAN
24) What barrier is built to hold a portion of floodwater in a reservoir and help control flooding? DAM
25) What is one way farmers conserve water used on crops? DRIP IRRIGATION
26) Wastewater discharged from a factory, which kills fish in a nearby river, is an example of? WATER POLLUTION
27) What is an example of a system that moves water between places in California? AQUEDUCT
28) What is one goal of water-quality legislation? CLEAN SWIMMING WATER
29) Restoring the ability of people to fish and swim safely was a goal of the what? CLEAN WATER ACT OF 1972
30) Waste material introduced into a river by runoff from land is called? WATER POLLUTION
31) One way for industries to conserve water is to RECYCLE WATER
32) If a stream has a bed load, it is more likely to cause what? EROSION
