From towering mountains to pebbles along a river, the Earth is made of a huge variety of rocks. In today's episode, we're going to follow the rock cycle of a piece of granite in the Himalayan mountains, and as you'll see, every rock has a far-reaching story to tell often millions of years in the making.

@catfishmudflap2 years ago Shouldn' t you say theis rock, not rocks. What people call rocks are generally stones, which are classified as boulders (large stones) stones (of particular size) and pebbles (small stones) i am aware that in the vernacular there is no difference, and everything is rocks. However, in geology they arestones are formed from rock as a result of mechanical or chemical weathering. ...Expand
