Environmental Science Concepts

Front

Sustainability

Back

Meeting our needs without compromising future generations ability to meet their needs.

Front

Environmental Impact

Back

The effect of human activities on the natural environment.

Front

Deforestation

Back

The permanent removal of forests (trees).

Front

Hydraulic Fracturing (Fracking)

Back

A technique for extracting oil and natural gas from deep, underground rock formations.

Front

Greenhouse Gases

Back

Atmospheric gases that trap heat contributing to greenhouse effect and climate change. Key examples include water vapor, carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

Greenhouse effect

Back

The process through which heat is trapped near Earth's surface by substances known as greenhouse gases.

Front

Renewable Energy Resources

Back

Naturally replenish over time or can be used indefinitely (wind, solar energy, geothermal, etc.).

Front

Non-Renewable Resources

Back

Exist in limited finite quantities and are used much faster than they can be replenished (Fossil fuels, coal, natural gas).

Front

Natural Resources

Back

Materials or substances occurring in nature which can be exploited for economic gain (for example, forests, water and fertile land).

Front

Fossil Fuels

Back

Non-renewable energy sources such as coal, coal products, natural gas, derived gas, crude oil, petroleum products and non-renewable wastes.
