Environmental Science Final Exam Review

Front

Which of the following is an example of a nonrenewable natural resource? Options: wind energy, sunlight, natural gas, geothermal energy.

Back

natural gas

Answer explanation

Natural gas is a nonrenewable resource because it forms over millions of years from decomposed organic matter and cannot be replenished on a human timescale. In contrast, wind, sunlight, and geothermal energy are renewable resources.

Front

Front

Which energy source is limited and might run out if used up?

Back

Coal

Answer explanation

Coal is a finite resource because it is formed over millions of years from organic matter and cannot be replenished on a human timescale. In contrast, wind and solar energy are renewable resources that can be harnessed continuously.

Front

Type of radiation often associated with warmth and heat?

Back

heat

Answer explanation

Infrared radiation is primarily associated with heat, as it is emitted by warm objects and is responsible for thermal energy transfer. The other options, like microwaves and X-rays, are different types of electromagnetic radiation.

Front

What have the sea surface temperatures been doing lately?

Back

Increasing

Answer explanation

Sea surface temperatures have been increasing due to climate change, which leads to higher ocean temperatures. This trend is supported by extensive scientific data and observations.

Front

Which of these is NOT a sneaky pollutant lurking around CAFOs? Options: Ammonia, Hydrogen Sulfide, Cinnamon, Methane

Back

Cinnamon

Answer explanation

Cinnamon is a spice and not a pollutant. In contrast, ammonia, hydrogen sulfide, and methane are common pollutants emitted from Concentrated Animal Feeding Operations (CAFOs), making cinnamon the correct choice.

Front

35% of the electricity production in the US comes from which source?

Back
