Question 1 · 1 mark · Difficulty 1/3

Which of the following gases is the MAIN contributor to the enhanced greenhouse effect?

  1. Nitrogen
  2. Carbon dioxide
  3. Oxygen
  4. Argon
Show answer & explanation
✓ Answer: BCarbon dioxide
Award 1 mark for identifying carbon dioxide as the main greenhouse gas contributing to enhanced global warming. A is incorrect — nitrogen makes up 78% of the atmosphere but does not trap heat. C is incorrect — oxygen is essential for respiration but is not a greenhouse gas. D is incorrect — argon is an inert gas that does not absorb infrared radiation.
Question 2 · 1 mark · Difficulty 1/3

Which of the following human activities contributes LEAST to the greenhouse effect?

  1. Burning bagasse in sugar cane factories
  2. Deforestation for agriculture
  3. Using solar panels for electricity
  4. Operating bauxite processing plants
Show answer & explanation
✓ Answer: CUsing solar panels for electricity
Award 1 mark for recognising that solar energy production does not release greenhouse gases during operation. A is incorrect — burning bagasse releases CO₂, though it is considered carbon-neutral. B is incorrect — deforestation reduces carbon sinks and releases stored carbon. D is incorrect — bauxite processing requires significant energy, often from fossil fuels.

CXC CSEC Integrated Science: Climate Change, the Greenhouse Effect and Global Warming FAQ

How many CXC CSEC Integrated Science questions on Climate Change, the Greenhouse Effect and Global Warming are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Climate Change, the Greenhouse Effect and Global Warming for CXC CSEC Integrated Science, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CXC paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CXC CSEC students preparing for Integrated Science?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Climate Change, the Greenhouse Effect and Global Warming practice with other Integrated Science topics or even switch to a totally different CXC subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Climate Change, the Greenhouse Effect and Global Warming questions aligned to the official CXC CSEC Integrated Science syllabus?
Every question is written against the published CXC CSEC Integrated Science specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CXC.
How is Climate Change, the Greenhouse Effect and Global Warming typically tested on CXC CSEC Integrated Science papers?
Climate Change, the Greenhouse Effect and Global Warming appears across multiple question types on real CXC CSEC Integrated Science papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
