Questions With Correct Answers
Households (homes) use more water than factories. - CORRECT
| | | | | | | | |
ANSWER✔✔-true
A science student is asked to perform the water tests similar to those
| | | | | | | | | | | | |
you studied in objective 3 of this lesson. He selects four water samples
| | | | | | | | | | | | |
to test, one from each of the following locations: A, B, C, and D. If his
| | | | | | | | | | | | | | | |
hypothesis is that the paint company is polluting the water, what is
| | | | | | | | | | | |
wrong with his selection? - CORRECT ANSWER✔✔-Since each sample
| | | | | | | | |
selected is downstream from the plant, he will not be able to determine
| | | | | | | | | | | | |
if the pollution came from the plant or from a source farther upstream.
| | | | | | | | | | | |
Which property causes water to dissolve most substances? - CORRECT
| | | | | | | | | |
ANSWER✔✔-polarity
Which statement below is not a way in which water affects the earth
| | | | | | | | | | | | |
and the living things upon it? - CORRECT ANSWER✔✔-Water is the
| | | | | | | | | | |
power source that keeps the water cycle moving through all parts of the
| | | | | | | | | | | |
planet.
|
, All forms of rain, snow, or hail that fall to the earth from the atmosphere
| | | | | | | | | | | | | |
would collectively be called - CORRECT ANSWER✔✔-precipitation
| | | | | | |
Which property of water is created by the fact that opposite sides of the
| | | | | | | | | | | | |
water molecule have opposite electric charges? - CORRECT
| | | | | | | | |
ANSWER✔✔-bipolar
At site H the levels of cadmium are very high (levels above .001 are
| | | | | | | | | | | | | |
considered toxic). If the plant has been dumping cadmium into the
| | | | | | | | | | |
water for many years, what will the process of bio-magnification have
| | | | | | | | | | |
done to the level of cadmium in the vegetation and the animals living
| | | | | | | | | | | | |
along the river banks? - CORRECT ANSWER✔✔-The level of cadmium in
| | | | | | | | | | |
the vegetation and animals will be higher than the level of cadmium in
| | | | | | | | | | | | |
the water. |
Besides surface water, what reservoir is currently a significant source of
| | | | | | | | | | |
water for human use? - CORRECT ANSWER✔✔-ground water
| | | | | | |
What is the power source that drives the water cycle? - CORRECT
| | | | | | | | | | | |
ANSWER✔✔-heating from sunlight | |
Which property helps water to move up plant conductive tissue like
| | | | | | | | | | |
xylem and phloem? - CORRECT ANSWER✔✔-capillary attraction
| | | | | |
