*d. aquatic environments, forests and human environments
14) How does acid deposition impact aquatic environments?
@ Fish that absorb the chemicals die, become sterile, or produce mutated offspring and are too full of mercury to eat.
a. Fish do not often die, but they do become too full of toxins to be consumed by humans
b. Aquatic environments become temporarily lifeless while new species of fish who can tolerate the acid deposition replenish the stock
*c. Fish that absorb the chemicals either die, become sterile or produce mutated offspring, and are too full of mercury to eat
d. Aquatic environments are not directly impacted by acid deposition
15) What is the best solution to the problem of increasing acid deposition?
@ The best solution to the problem of increasing acid deposition is a combination of approaches including technical fixes such as clean coal technology, catalytic converters on cars, combined with schemes to reduce traffic in cities, education to encourage the public to use their cars less, and the further development of alternative fuels that are not harmful to the environment.
a. Clean coal technology
b. Encouraging citizens to use their cars less
c. Alternative bio-fuel development
*d. A combination of approaches including all of the above.
Objective D-2: Describe the effects of glacial processes on the Alps. Display 2 16) What caused most of the current landscape features of the Alps region.
@ Many of the landscape features found owe their origins to ice movement and deposition of eroded material.
a. Tectonic plate movement
*b. Ice movement and deposition of eroded material
c. Accelerated river erosion
d. Global warming
17) What is the difference between erosional landforms and depositional landforms?
@ Erosional landforms tend to be located where the ice developed and moved from, while depositional landforms tend dominate where the ice flowed to, namely towards the edges of an ice mass.
a. Erosional landforms dominate an area where the ice flows to, while depositional landforms are found where ice flows from.
b. Erosional landforms and depositional landforms are two words for the same type of landform.
*c. Erosional landforms occur where ice developed and moved from, while depositional landforms are found where ice flows to.
d. Erosional landforms and depositional landforms occur at the edges of an ice mass.
18) How were the deep ravines and rock steps of the Alps formed?
@ Thicker ice created greater erosion, causing deep ravines and rock steps. Faster flowing ice also created more erosion.
*a. thicker ice and faster flowing ice
b. slow ice melt due to low temperatures
c. thin layers of ice melting gradually over time
d. There are no deep ravines and rock steps in the Alps region.
19) What is glaciation?
@ Glaciation is where precipitation in the form of snow has covered an area and has eventually been converted into ice by force of gravity and pressure.
a. Glaciation is the process by which mountains are formed.
b. Glaciation is the process of melting ice caps due to global warming.
*c. Glaciation is the process whereby snow has been converted to ice by the force of gravity and pressure.
d. Glaciation is the process of ravine formation due to extensive ice coverage over a large area of land.
20) Where is most accumulation of glacial ice found?
@ The most accumulation of glacial ice is found near mountains or near the poles.
a. Arctic Circle
b. spread throughout the continents
c. predominantly near the equator, at high elevations
*d. mountains or near the poles
21) Generally when do glaciers advance downward, causing further erosional landforms?
@ During colder seasons glaciers tend to advance downward, causing further erosional landforms.
