Environmental Science Final Review

Front

What is global warming?

Back

Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases like carbon dioxide from burning fossil fuels.

What are greenhouse gases?

Back

Greenhouse gases are gases in Earth's atmosphere that trap heat. The main greenhouse gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor.

Front

What is acid rain?

Back

Acid rain is precipitation that has a lower pH than normal rainwater, caused by the release of sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere, which react with water to form acids.

Front

How can recycling help the environment?

Back

Recycling reduces the amount of waste sent to landfills, conserves natural resources, saves energy, and reduces pollution by decreasing the need for new materials.

Front

What is the impact of litter on wildlife?

Back

Litter can be harmful to wildlife as animals may ingest it thinking it is food, which can lead to injury or death.

Front

Why is it important to use alternative energy sources?

Back

Alternative energy sources, such as solar and wind, are important because they are renewable and can help reduce dependence on fossil fuels, which are finite and contribute to pollution.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, including coal, oil, and natural gas, used primarily for energy.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, keeping the planet warm enough to support life.

Front

What are the consequences of deforestation?

Back

Deforestation can lead to loss of biodiversity, disruption of water cycles, increased greenhouse gas emissions, and soil erosion.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the diversity of species, genetic variation, and ecosystem diversity.
