THE STORY OF SAND
Dear HIW,
Geography has always been my favourite subject and your magazine always teaches me interesting new facts. I wondered if you could answer my question. How long does it take to make the sand on beaches from rocks and how much does sand move over time?

Thanks for your letter, Emily. It’s great to hear you have a passion for geography and that you’re keen to further your knowledge. Sand is so plentiful along the world’s
