term - Fossil aquifer, confined aquifer, unconfined aquifer, transpiration, water table
4) After examining the graph below, which statement best describes the main conclusion illustrated in the figure?
a. Carbon dioxide and methane gases have changed drastically over the last 400,000 years but are not correlated with changes in temperature or sea level..
b. Carbon dioxide and methane gases have continually increased over the last 400,000 years.
c. Carbon dioxide and methane gases have changed drastically over the last 400,000 years and these changes correlate with global temperature and sea level changes.
Which of the following statements would be the best precaution given your answer to the first part of this question?
a. Emissions of carbon dioxide by humans should be minimized to avoid increasing global temperatures.
b. Emissions of methane by humans should be maximized to avoid increasing global temperatures.
c. Emissions of carbon dioxide and methane by humans will have no effect on global temperatures.
5) Select all of the following that are considered consequences of human induced climate change. (Hint: there are only two answers that are not considered consequences)
6) Which of the following statements best describes the resource fresh water?
a. Fresh water is a non-renewable resource because once it is used, it can never be reused or recycled.
b. Fresh water is a perpetual renewable resource because it can be recycled over and over again through ecosystems
c. Fresh water can be a renewable resource if it's used sustainably in a given region and it doesn't get polluted
7) Match the pro or con with the correct source of freshwater.
1. Accessible all year
Surface water Ground water
2. Directly dependent on snow melt and precipitation rates
Surface water Ground water
3. Generally easier to access
Surface water Ground water
4. Once polluted, it's almost impossible to clean up
Surface water Ground water
8) Which of the following statements about water resource use is FALSE? [answer1]
a. It is not economically and technically feasible to reduce water waste by 15% to meet most of the world's water needs
b. Two-thirds of the water used throughout the world is unnecessarily wasted through evaporation, leaks, and other loses.
c. About half the water drawn from surface and groundwater supplies is unnecessarily wasted in the US.
9) Match the pro or con with the correct method for accessing fresh water.
1. flood control ____________
2. generally cheaper source of freshwater than surface water ____________
3. potentially the largest resource ____________
4. most expensive in terms of energy and maintenance ____________
5. disrupts ecosystems, especially spawning fish ____________
6. Subsidence can occur if overused ____________
7. Can initially supply large amounts of water using tunnels and canals ____________
8. can greatly increase salinity of lakes or inland seas ____________
method - desalination, dams and reservoir, groundwater well, water transfer projects ____________
10) Match the solution with the correct water waste source.
1. subsidize water conservation ____________
2. landscape with native plants____________
3. monitor soil moisture to minimize water use____________
4. reduce deforestation ____________
water waste source - water waste from flooding, water waste due to general unsustainable use, water waste in industry and homes, water waste in irrigation
11) Match the following sources/processes with the correct greenhouse gas or gases.
1. Combustion of fossil fuels ____________
2. Melting permafrost____________
3. wetlands & rice paddies ____________
4. deforestation ____________
5. belching cows
gas - methane, CO2, methane & CO2
12) Referring to the graph shown below, which of the following statements best describes the trend in global sea ice coverage in the past 1400 years plus?
a. Total ice coverage has fluctuated but increased over the last 1400 years, with it's greatest extent in the last 50 years.
b. Total ice coverage has remained relatively constant at 10 million square km for the last 1400 years until about 1960 when it dramatically decreased.
c. Total ice coverage has steadily decreased over the last 1400 years.
Which of the following would be the most likely causes of the trend described in the previous question?
a. Carbon dioxide emissions were high for 1000's of years during the Agricultural Revolution, and rapidly dropped in the last 150 years, causing the changes seen in sea ice coverage.
b. Emissions of carbon dioxide remained relatively low over the past few 1000 years, then increased steadily after the Industrial Revolution and correlate well with the trends in sea ice cover over the last 1400 years.
c. Emissions of carbon dioxide and methane by humans had no effect on global temperatures and melting of sea ice over the last 1400 years.
1. degradation of coastal habitats by rising sea levelsExplanation / Answer
1) a
weather is described as the phenomenon of heat , cold, rain, air wind, humidity etc as experienced on day to day basis. climate is much broader term which is averaged influence of many atmospheric phenomenon that prevail for hunderds and thousands of years
