One of the National Academy of Engineering Grand Challenges for Engineering is Manage the Nitrogen Cycle. It is important to control the agricultural impact on the nitrogen cycle as engineers attempt to provide a sustainable food supply. To grow an experimental crop to test a new​ fertilizer, you create a small “farm” with the soil at a depth of 9.5 inches​ [in]. You use 200 buckets of​ soil, and each bucket holds 5 gallons​ [gal] of soil. What is the area of your “farm”in units of square feet [ft2​]?

Environmental Consequences of Fossil Fuel Use

Fossil fuels are organic materials found inside the earth's surface. They are mainly composed of dead remains of plants and animals. The primary component constituents of fossil fuels are carbon and hydrogen, which are usually burnt to produce energy. Fossil fuels are believed to be formed millions of years ago when dead remains of animals and plants were subjected to high heat and pressure.
