ES Unit 1 Test 25-26

What does the environment include?

• Only living things
• Only non-living things
• Both living and non-living things, but not humans
• Both living and non-living things, including humans
• Only humans

Which of the following best defines environmental science?

• A movement dedicated to protecting the environment
• The study of living organisms and the processes that allow them to survive
• The study of interactions between the natural world and humans
• The study of Earth's physical structure and processes

Environmental science is considered interdisciplinary because:

• It focuses on only one area of study
• It includes multiple fields, such as politics, ethics, and economics in addition to science
• It is not technically a scientific field, but a political and social movement
• It excludes human involvement and only focuses on the natural world
• Many scientists are involved in the field and must collaborate

Unlike environmental science, environmentalism primarily focuses on:

• Data collection and hypothesis testing
• Policy changes and advocacy to reduce human impact
• The formation of new scientific theories about ecosystems
• The geological structure of Earth's layers

How do environmentalism and environmental science overlap?

• Environmentalism uses data from environmental science to promote action
• They have no connection
• Environmental science is a branch of environmentalism
• Environmentalism focuses on the natural world; environmental science focuses on human impacts on the natural world

Who is an example of an environmentalist?

• Albert Einstein
• Marie Curie
• Louis Pasteur
• Rachel Carson

What is a system?

• A randomly assembled group of unrelated objects
• A collection of parts that function independently without affecting each other
• A set of parts that interact and impact each other
• A single component that operates in isolation from other

Which of these is not an example of a system?

• The water cycle
• The biosphere
• A raindrop
• A food web
• These are all examples of systems

Which type of feedback loop is described? Deforestation leads to soil erosion, which reduces vegetation growth and causes further deforestation.

• Positive feedback loop
• Negative feedback loop

Which feedback loop is more common in environmental systems?

• Positive, it destabilizes systems, amplifying change
• Negative, it stabilizes systems, promoting balance
• Positive, it stabilizes systems, promoting balance
• Negative, it destabilizes systems, amplifying change
