An environmental engineer wants to examine the permeability of different soils to determine the best natural containment system to protect groundwater from pollutants. The engineer tests four different soil samples, places them into a wet column, and pours 50mL of water over each sample. The engineer records the total amount of water that moves through the column as well as the total amount of time for the water to fully percolate through the soil. The data from the study are shown below. Which of the following best describes the independent variable in this research design?
Sample | Flow Time (seconds) | Total Volume of Water Recovered (mL) | Permeability of Soil Sample (mL/sec) |
1 | 2.7 | 43.5 | 17.96 |
2 | 2.2 | 27.9 | 12.63 |

Which of the following best explains why City B regularly receives less precipitation than City A? Starting from here, form B
As air rises up the side of the mountain near City B, the temperature and the relative humidity increase, causing increased precipitation on the other side of the mountain over City A.
The rain shadow effect causes City B to be drier because the mountain blocks precipitation from reaching the city.
Air that is forced upward on the side of the mountain near City B leads to the formation of stratospheric clouds
The Urban heat island from City B causes a warmer climate that leads to reduced cloud formation.

Which of the following best describes why understanding a watershed and its boundaries is important in designing housing developments along a river?
Watersheds provide habitats for hundreds of marine species, so it is important to protect their feeding and nesting sites when designing housing for humans.
The water contained in a watershed is more likely to become polluted if the soil has high permeability, so it is important to locate all point sources to reduce contamination
Watersheds provide space for cultivating land to produce food and other products, so it is important to avoid locating a housing development on the most fertile land.
Surface water and stormwater runoff will drain downstream within the watershed boundaries, so it is important to understand the flow of water through the watershed.

all fertilizers have three small numbers on their container. The first number is the amount of nitrogen and the second number is the amount of phosphate and the third number is the amount of potash. These numbers represent the primary nutrients needed in soil- nitrogen, phosphorus, and potassium.
Why should farmers, gardeners, and landscapers be careful about the amount of nitrogen and phosphorus they add to the soil?
These nutrients are broken down by microbes in the soil, releasing large amount of nitrous oxide, a greenhouse, gas into the atmosphere
These nutrients are harmful to pets, small children, and other animals
