Environmental Impact Flashcard

Front

What is agricultural runoff?

Back

Agricultural runoff is water that flows over agricultural land, carrying with it nutrients, pesticides, and other pollutants into nearby water bodies.

Front

Why does agricultural runoff negatively impact water quality?

Back

It contains high concentrations of nutrients and pesticides, which can lead to algae blooms and unsafe drinking water.

Front

What are chlorofluorocarbons (CFCs)?

Back

CFCs are chemical compounds that were commonly used in refrigeration and aerosol propellants, known for their harmful effects on the ozone layer.

Front

What is a key advantage of nuclear energy over fossil fuels?

Back

Front

What is the main environmental concern with fossil fuels?

Back

Fossil fuels release greenhouse gases, contributing to climate change and air pollution.

Front

What is solar energy?

Back

Solar energy is energy harnessed from the sun's rays, which can be converted into electricity or heat.

Front

What is the significance of minimal maintenance in solar energy systems?

Back

Minimal maintenance means lower long-term costs and less environmental impact compared to other energy sources.

Front

What is the land-use footprint of solar panels on existing structures?

Back

Solar panels on existing structures typically have the smallest land-use footprint among renewable energy sources.

Front

What are the environmental impacts of wind farms?

Back

Wind farms can impact local wildlife, particularly birds and bats, and may require significant land use.

Front

What is biomass energy?

Back

Biomass energy is produced from organic materials, such as plant and animal waste, and can be used for heating or electricity.
