How Does a Waterfall Shape Rock? A River Song for Kids

Ke mana tetes berkilau melaju? Aliran gunung meliuk di lereng Melewati pasir, kerikil bundar Lalu mencapai undakan batu tinggi Gravitasi menjatuhkannya dari tepi Batu keras di atas lapisan lunak Yang di bawah lebih cepat terkikis Sungai jatuh dari undakan batu Air terjun, tirai putih berkilau Arus terus mengukir batu Pelan-pelan, tepinya berubah Di bawah, air berbusa dan berputar Membawa pasir dan kerikil kecil Campurannya mengikis batu lunak Perlahan serpih lepas: itulah erosi Rongga membesar di bawah batu keras Sungai jatuh dari undakan batu Air terjun, tirai putih berkilau Arus terus mengukir batu Pelan-pelan, tepinya berubah Bertahun-tahun, batu keras menjorok Lalu sebongkah batu pun terlepas Undakan mundur sedikit ke hulu Sungai jatuh dari undakan batu Air terjun, tirai putih berkilau Arus terus mengukir batu Pelan-pelan, tepinya berubah Di bawah, arus mengukir ngarai batu Air terjun menderu dari tepi baru

Where is that shining droplet racing? A mountain stream curls down the slope It slips past sand and rounded pebbles And reaches one high rocky ledge Gravity pulls it off the edge Hard rock rests on a softer layer The softer layer wears away faster A river falls from a rocky ledge Waterfall, a bright white curtain Flowing water slowly carves the rock Little by little, it shapes the edge At its foot, the foaming water swirls It carries sand and little pebbles The swirling mix scrapes soft rock loose That slow wear and breaking is erosion A hollow grows beneath the hard shelf A river falls from a rocky ledge Waterfall, a bright white curtain Flowing water slowly carves the rock Little by little, it shapes the edge After many years, the shelf overhangs Then a block of rock breaks away The waterfall edge shifts upstream A river falls from a rocky ledge Waterfall, a bright white curtain Flowing water slowly carves the rock Little by little, it shapes the edge Below, the river carves a rocky gorge The waterfall roars at its new edge
