In addition to frost wedging, rain is also an important part in shaping hoodoos.

Additionally, as lane collects Carbon Dioxide as it falls, it turns into a weak acid like substance, slowly melting down at limestone, until it creates a deep cave like feature. Things like stalactites form when rain water falls down through limestone, collecting calcium carbonate and eventually forming stalagmites, and what seems like rocks just hanging from the roofs of caves. ]]> 2017-11-07 14:55:00 UTC https://padlet.com/20529152/bu5w295bwhr6/wish/204375926 20529152 https://padlet.com/20529152/bu5w295bwhr6/wish/204381394 As glaciers gain mass over time, they begin to become over massive and begin to crush down on themselves forming many different things.
Arete-  The Arete is the narrow part of land that seperates two valleys, looking much like an upside down V in shape, It is formed when two very close glaciers form, and as they crack down, it creates two valleys and the point in the middle is the Arete.
Cirque- As the glacier begins to crush down on bedrock, it creates a valley in the mountains, almost the shape of an amphitheater.
U-Shaped Valley- U shaped valleys are formed when glaciers travel down a slope, tearing away at the rock very quickly because of it's high mass. They create a shape that looks much like a U with a rounded trough and straight vertical sides.
Hanging Valley- Hanging Valleys are valleys that are much higher up than the real main valley, almost like a precursor to the real valley, they usually are formed just as a glacier is beginning to slide, as they mostly come from U shaped valleys. 
Horn- When three or more glaciers erode an Arete, then they create a very sharp pointed shape that is called a horn. 
Moraines- Moraines are the accumulation of dirt and rock that are on a glacier, and as the glacier retreats the rock and dirt is left behind, creating moraines.

Flows, Slides, and falls- These occur when rock free-falls, or other types of materials, and this usually occurs when rock has been made weak by erosion, then through gravity the rock is pulled down very quickly, counting as "Extremely Quick Erosion" 
Creeps- Creeps are the slow down slide movement of soils and other particles, slowly turning a sloped surface into a steep sloped surface as more and more loose particles continue their movement down the hill. 
Rock Falls- Rock slides Falls occur when large rocks are dislodged, and they fall straight down or roll down a steep surface causing mass amounts of erosion along the way. 
Slumps- Slumps occur when amounts of sediment break off of an overhang or hill and move a short distance downhill to a new location, and if significant enough it could turn into a flow. ]]> 2017-11-07 15:18:00 UTC https://padlet.com/20529152/bu5w295bwhr6/wish/204391423
