A geothermal power station in Iceland uses thermal energy from underground rocks to generate electricity. Which statement correctly describes this energy resource?

Q: How do I try a free CIE Physics question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CIE IGCSE Physics bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CIE Physics students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Physics questions aligned to the CIE IGCSE syllabus?

Every question is written against the published CIE IGCSE Physics syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CIE past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A geothermal power station in Iceland uses thermal energy from underground rocks to generate electricity. Which statement correctly describes this energy resource?

Accepted Answer

It can only be built in volcanic regions or areas with hot rocks near the surface. — Award 1 mark for recognising that geothermal energy requires specific geological conditions. A is incorrect — geothermal power stations produce minimal carbon dioxide during operation. C is incorrect — geothermal energy comes from radioactive decay in the Earth's core, not fossil fuels. D is incorrect — no fuel needs to be transported as the heat source is underground at the site.

Answer

It uses energy originally stored in fossil fuels.

Answer

It requires a continuous supply of fuel to be transported to the station.

Answer

It produces large quantities of carbon dioxide during operation.

Answer

It can only be built in volcanic regions or areas with hot rocks near the surface.
