What is a light-year?

  1. The distance light travels in one year (about 9.46 trillion km)
  2. One year on another planet
  3. The brightness of a star
  4. The time it takes light to reach Earth
Show answer & explanation
✓ Answer: A — The distance light travels in one year (about 9.46 trillion km)
A light-year is a unit of distance, not time. Light travels at ~300,000 km/s, so in one year it covers about 9.46 × 10¹² km. It is used to measure vast astronomical distances.

  3. The theory that Earth was created 6,000 years ago
  4. The theory that the universe is shrinking
Show answer & explanation
✓ Answer: A — The theory that the universe began as a singularity approximately 13.8 billion years ago and has been expanding since

US Common Core Common Core Earth & Space Science: Space and the Universe FAQ

Is Kramizo free for US Common Core Common Core students preparing for Earth & Space 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 Space and the Universe practice with other Earth & Space Science topics or even switch to a totally different US Common Core 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 Space and the Universe questions aligned to the official US Common Core Common Core Earth & Space Science syllabus?
Every question is written against the published US Common Core Common Core Earth & Space Science specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real US Common Core 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 US Common Core.
How is Space and the Universe typically tested on US Common Core Common Core Earth & Space Science papers?
Space and the Universe appears across multiple question types on real US Common Core Common Core Earth & Space 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.
