Freshwater Review Part 1

1. Nina does a WQI for her local pond and discovers that her pond’s WQI is bad. Which of the following would NOT contribute to this reading?

• 1. A pH of 3

• 1. An aquatic temperature change of 4°C throughout the day

• 1. E. Coli measurement of 200

• Turbidity of 5

Which of the following is TRUE about WQI?

• Runoff from fertilizers does not affect phosphate levels at all

• 1. Dark water tends to hold less heat

• 2. Nitrates are necessary in a healthy water environment

• 1. Pure water contains unequal amounts of H+ and OH- usually. The closer these are to equal, the poorer the water quality.

Which of the following statements about this chart are FALSE?

• The water quality is good

• The pH is basic, because it's above 7

• The temperature stays consistent throughout the day--or at least consistent in the measurements taken

• The lowest value is in the E. coli

Select the answer which has them in the right order, from A, B, C, and D.

• Stream, bedrock, confined aquifer, water table

• Bedrock, stream, water table, confined aquifer

• Water table, stream, bedrock, confined aquifer

• Bedrock, confined aquifer, water table, stream

Daniella is living in a town which experiences frequent rainfall. The land in this town was converted ten years ago from rich woodlands to paved urban paradise. Which of the following statements is likely TRUE?

• The watershed is in deficit, and it is leading to drought.

• The watershed is in surplus, and it is leading to drought.

• The watershed is in deficit, and it is leading to flooding.

• The watershed is in surplus, and it is leading to flooding.

Which of the following locations has a watershed which is fed by the Connecticut river?

• Pittsfield

• Springfield

• Brockton

• Newport

1. It is early spring, and Marius is hiking up a Swiss mountain, about a two-hour hike. He begins hiking in the afternoon, with a moderately warm temperature, and a clear sky. Which of the following types of water/parts of the water cycle is Marius not likely to encounter?

• Dew

• Snowmelt runoff

• Groundwater recharge and flow

• Permafrost

Which of the following is NOT a quality water has?

• Water can be easily drawn up by plant roots

• Water temperature changes very easily, allowing it to benefit organisms that need it

• Water dissolves many things, making it a universal solvent

• When water freezes, the particles get further apart, allowing it to rise to the surface

Which of the following sequences correctly represents the water cycle from evaporation to precipitation?

• Evaporation, Condensation, Precipitation, Collection

• Condensation, Evaporation, Collection, Precipitation

• Collection, Evaporation, Precipitation, Condensation

• Precipitation, Collection, Evaporation, Condensation

BONUS: Which of the following statements is FALSE about the water cycle?

• The water cycle is a closed system, meaning that the amount of water on Earth remains constant over time.

• The water cycle is driven by the sun’s energy, which causes water to evaporate from the surface and condense in the atmosphere.

• The water cycle involves various processes such as precipitation, infiltration, runoff, transpiration, and sublimation.

• The water cycle is affected by human activities, such as deforestation, irrigation, and greenhouse gas emissions.

Answer explanation

The water cycle is not affected by human activities, such as deforestation, irrigation, and greenhouse gas emissions. This statement is false because human activities can alter the water cycle in various ways. For example, deforestation can reduce the amount of water that is transpired by plants and returned to the atmosphere, irrigation can increase the amount of water that is evaporated from the surface and depleted from the groundwater, and greenhouse gas emissions can increase the global temperature and change the patterns of precipitation and evaporation. Therefore, human activities can have significant impacts on the water cycle and the availability and quality of water resources.
