Wind transports sand across the sand dunes that causes abrasion, it's when sand scrapes against rocks and creates damage. Wind can tear down land forms and erode sediments.]]> 2017-11-06 16:12:23 UTC https://padlet.com/21607161/4c6evdh2wwcz/wish/203961792 21607161 https://padlet.com/21607161/4c6evdh2wwcz/wish/204021536 2017-11-06 17:51:19 UTC https://padlet.com/21607161/4c6evdh2wwcz/wish/204021536 21607161 https://padlet.com/21607161/4c6evdh2wwcz/wish/204023076 Frost wedging is the main process that forms the hoodoos. As water from snow melts, it creeps up into the cracks of the rocks, then as it freezes it expands and cracks the rocks. After multiple processes the rocks form a hoodoo. Dissolution also occurs because of the acidic rainwater breaks down limestone.]]> 2017-11-06 17:53:58 UTC https://padlet.com/21607161/4c6evdh2wwcz/wish/204023076 21607161 https://padlet.com/21607161/4c6evdh2wwcz/wish/204031991 2017-11-06 18:09:11 UTC https://padlet.com/21607161/4c6evdh2wwcz/wish/204031991 21607161 https://padlet.com/21607161/4c6evdh2wwcz/wish/204032320 2017-11-06 18:09:40 UTC https://padlet.com/21607161/4c6evdh2wwcz/wish/204032320 21607161 https://padlet.com/21607161/4c6evdh2wwcz/wish/204032976 2017-11-06 18:10:39 UTC https://padlet.com/21607161/4c6evdh2wwcz/wish/204032976 21607161 https://padlet.com/21607161/4c6evdh2wwcz/wish/204366457 Dissolution happened in cold wet winters when rain dissolved the limestone rocks that hap been placed down.
