This field of study focuses on the interactions between humans and the natural world. 

What is Environmental Science?

100

This term describes a group of different species living and interacting in the same area.

What is a community?

100

This is the outermost layer of the Earth where tectonic plates are located.


What is the lithosphere?

100

This is the most widely used energy source worldwide today.


What is fossil fuels?

100

This term refers to the contamination of water by harmful substances like chemicals or pathogens.

What is water pollution?

200

These resources, such as sunlight and wind, replenish naturally over short periods of time. 

What are renewable resources? 

200

These organisms make their own food using sunlight or chemicals.

What are producers?

200

Earthquakes commonly occur at this type of plate boundary where two plates slide past each other.


What is a transform boundary?

200

Using wind or solar energy helps the environment because they produce no direct air pollution or these harmful emissions.


What is they produce no direct air pollution or greenhouse gas emissions?

200

Bacteria, viruses, and parasites are examples of this type of water pollutant.

What are biological pollutants?

300

This term describes the impact a person or population has on land, water, and resources? 

What is an ecological footprint? 

300

What would most likely happen to the population of secondary consumers if the primary consumers in an ecosystem were removed?

What is their population would decrease due to lack of food?

300

Seasonal changes on Earth are caused by this characteristic of Earth’s movement.


What is the tilt of Earth’s axis?

300

This air pollutant is a primary contributor to acid rain and is released mainly by burning fossil fuels.


What is sulfur dioxide (SO₂)?

300

Excess nitrogen and phosphorus entering a body of water can cause this process, which leads to algae blooms and oxygen depletion.

What is eutrophication?

400

Name two environmental indicators used to evaluate the health of the planet. 

What are average global temperature and resource depletion? 

400

This type of population growth occurs when resources are unlimited, and the population increases rapidly.

What is exponential growth?

400

This process occurs when fertile land degrades into desert due to drought, deforestation, or poor farming practices.


What is desertification?

400

Nitrogen oxides and volatile organic compounds react in sunlight to form this type of smog.


What are nitrogen oxides (NOx) and volatile organic compounds (VOCs)?

400

This greenhouse gas is the most abundant contributor to global warming.


What is carbon dioxide?

500

This concept explains how individuals acting in their own self-interest can overuse and deplete shared resources. 

What is the tragedy of the commons? 

500

Which type of survivorship curve (Type I, II, or III) represents species that have high parental care and low infant mortality?

What is Type I?

500

This irrigation method conserves water by delivering it directly to the roots of plants.


What is drip irrigation?

500

Burning biomass for cooking and heating is a major source of this type of indoor air pollution in developing countries.


What is the burning of biomass for cooking and heating?

500

Rising sea levels, more extreme weather events, and loss of biodiversity are major impacts caused by this global phenomenon.


What is climate change?
