Environmental Science Quiz

What is the Water Cycle?

• A cycle involving the continuous circulation of water in the Earth-atmosphere system

• A process where carbon atoms travel from the atmosphere to the Earth

• The global sum of all ecosystems on Earth

• A process that occurs when gases in Earth’s atmosphere trap the Sun’s heat

Which of the following best describes the Carbon Cycle?

• The envelope of gases surrounding the Earth

• The process in which carbon atoms travel from the atmosphere to the Earth and back

• A process that occurs when gases in Earth’s atmosphere trap the Sun’s heat

• The global sum of all ecosystems on Earth

What is the Biosphere?

• The global sum of all ecosystems on Earth

• All the water on the Earth’s surface

• The envelope of gases surrounding the Earth

• A process that occurs when gases in Earth’s atmosphere trap the Sun’s heat

What is the Geosphere?

• Any of the almost spherical concentric regions of matter that make up the Earth and its atmosphere

• The global sum of all ecosystems on Earth

• The envelope of gases surrounding the Earth

• All the water on the Earth’s surface

What is the role of trees in the Carbon Cycle?

• They trap heat in the atmosphere

• They are a type of biome with high biodiversity

• They are natural regulators that remove carbon dioxide from the atmosphere

• They absorb carbon dioxide through photosynthesis and store it in their wood, leaves, and roots

What is the Greenhouse Effect?

• The process in which carbon atoms travel from the atmosphere to the Earth and back

• A process that occurs when gases in Earth’s atmosphere trap the Sun’s heat

• The envelope of gases surrounding the Earth

• The global sum of all ecosystems on Earth

What is Carrying Capacity?

• The process in which carbon atoms travel from the atmosphere to the Earth and back

• The maximum number of individuals of a particular species that a particular environment can support

• A process that occurs when gases in Earth’s atmosphere trap the Sun’s heat

• The global sum of all ecosystems on Earth

What is Exponential Growth?

• Under ideal conditions with unlimited resources, a population will grow exponentially

• When a population’s growth slows and then stops

• The maximum number of individuals of a particular species that a particular environment can support

• A process that occurs when gases in Earth’s atmosphere trap the Sun’s heat

What is Logistic Growth?

• The maximum number of individuals of a particular species that a particular environment can support

• Under ideal conditions with unlimited resources, a population will grow exponentially

• When a population’s growth slows and then stops, following a period of exponential growth

• A process that occurs when gases in Earth’s atmosphere trap the Sun’s heat

What are Density-Dependent Factors?

• Factors that operate strongly when population density reaches a certain level

• Factors that affect all populations regardless of population size and density

• The maximum number of individuals of a particular species that a particular environment can support

• A process that occurs when gases in Earth’s atmosphere trap the Sun’s heat
