Why is the greenhouse effect given that name?
Correct answer: B. The greenhouse effect is named because it describes the process by which greenhouse gases trap heat, similar to how a greenhouse's glass structure traps heat.
- A. The greenhouse effect is named for the environmental goal of planting more trees to combat global warming.
- B. The greenhouse effect is named because it describes the process by which greenhouse gases trap heat, similar to how a greenhouse's glass structure traps heat.
- C. The term was coined by a scientist who had a preference for the color green.
- D. None of the above options accurately describes the origin of the term 'greenhouse effect.'
Explanation
The term 'greenhouse effect' is used because Earth's atmosphere acts in a manner similar to a greenhouse. Just as the glass in a greenhouse allows sunlight to enter and prevents heat from escaping, greenhouse gases in the atmosphere trap heat, maintaining the planet's temperature. Option B correctly captures this analogy. Option A confuses the term with environmental actions. Option C incorrectly attributes the term to personal preferences, and Option D is invalid because Option B is a correct explanation.

About Scientific Reasoning
Scientific reasoning evaluates hypotheses through observations, variables, controls, measurements and experimental results. Questions involve identifying independent and dependent variables, recognising a fair test, interpreting tables or graphs, distinguishing evidence from opinion, and deciding whether data supports, rejects or leaves a hypothesis unresolved.
