What began as a mountain in the clouds forms a mountain in the ocean… and the cycle begins again.   Extra nonfiction content at the back of the book gives readers a more in-depth look at how scientists classify different rock sizes.   A gorgeous introduction to the rock cycle for the youngest geologists.","brand":"Post Wave Publishing UK Ltd","offers":[{"title":"Default Title","offer_id":67706059096352,"sku":"9781836271598","price":11.04,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/2812\/7264\/files\/9781836271598_3102772.jpg?v=1791491657","url":"https:\/\/bookcorner.com\/products\/mountain-boulder-pebble-sand-rebecca-van-slyke-9781836271598","provider":"The Book Corner","version":"1.0","type":"link"}
