{"product_id":"mountain-boulder-pebble-sand","title":"Mountain, Boulder, Pebble, Sand","description":"Crrr-ack!A boulder falls from a mountain and cracks into cobbles, which transform into pebbles, then granules, then sand, and silt. 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":58338971681103,"sku":"9781836271598","price":21.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0061\/0372\/8217\/files\/9781836271598_1-mountain-boulder-pebble-sand.jpg?v=1785320487","url":"https:\/\/www.suomalainen.com\/products\/mountain-boulder-pebble-sand","provider":"Suomalainen.com","version":"1.0","type":"link"}
