The rain (hydrolysis) slowly dissolves the sandstone, which makes the hoodoo look more bumpy and deformed.]]> 2017-11-02 19:01:52 UTC https://padlet.com/20392472/slc333b4hm6z/wish/203082160 20392472 https://padlet.com/20392472/slc333b4hm6z/wish/203342200 A pinnacle is formed by tree roots, abrasions, and hydrolysis. The plants roots make the cracks in the rock expand, which then allows the water to then get into those cracks to break down the rock even more that dissolves the sandstone a little at time. Then, the abrasions then formed the pinnacles even more to make them look like they do today.]]> 2017-11-03 15:31:51 UTC https://padlet.com/20392472/slc333b4hm6z/wish/203342200 20392472 https://padlet.com/20392472/slc333b4hm6z/wish/203356255 An arch is formed by hydrolysis, after the rocks have raised from a lower sea level, then after some erosion forces take place, the water comes in and breaks down the rocks in the middle, which creates the arch. The water mostly creates the arches by breaking off parts of the sandstone in the center. ]]> 2017-11-03 15:57:39 UTC https://padlet.com/20392472/slc333b4hm6z/wish/203356255 20392472 https://padlet.com/20392472/slc333b4hm6z/wish/203364824 A talus slope is formed by exfoliation because it is the accumulation of the rocks at the bottom of a cliff after the layers have peeled off of that same cliff. At the bottom of the cliff, you can see all the rocks that have come off accumulated at an angle, which is where the term slope comes from.]]> 2017-11-03 16:13:42 UTC https://padlet.com/20392472/slc333b4hm6z/wish/203364824 20392472 https://padlet.com/20392472/slc333b4hm6z/wish/203369115 A V-shaped valley is formed by frost wedging, because it is from the freeze thaw cycles that cause the valley to take the shape of a V. Also, another contributing factor of creating this are abrasions, which breaks done rock on the side of the valley to also form the sides and the dent in the middle.]]> 2017-11-03 16:21:43 UTC https://padlet.com/20392472/slc333b4hm6z/wish/203369115 20392472 https://padlet.com/20392472/slc333b4hm6z/wish/203373399 A meandering stream is formed by abrasions by creating a river that occurs in the middle or lower course. These rivers are rivers that curve, and at those curves, the river moves the fastest, which breaks done the sediments on the banks, to make the river bigger as time goes on]]> 2017-11-03 16:28:56 UTC https://padlet.com/20392472/slc333b4hm6z/wish/203373399 20392472 https://padlet.com/20392472/slc333b4hm6z/wish/203378474 An Ox - Bow lake is formed by the result of a meandering stream's erosion on the bends of the stream.  When the abrasion process continues on until it has become bigger and bigger until the loops are much too big and consume too much energy, the stream finds a new path that doesn't take too much energy. After the stream stops connecting to the now lake, it forms an ox - bow lake.]]> 2017-11-03 16:39:12 UTC https://padlet.com/20392472/slc333b4hm6z/wish/203378474 20392472 https://padlet.com/20392472/slc333b4hm6z/wish/203491057 A sinkhole is formed by hydrolysis, which is a gradual process that uses water to break done the limestone, and the water is then displaced. After this happens to the water, underground spaces develop, and once they become too big, the ground above collapses, which creates the sinkholes. ]]> 2017-11-03 23:29:24 UTC https://padlet.com/20392472/slc333b4hm6z/wish/203491057 20392472 https://padlet.com/20392472/slc333b4hm6z/wish/203491600 Caverns are formed by hydrolysis and dissolution that make the caverns into how they look, so its eroding the land to have a hole in it. Stalagmites and stalactites are formed by hydrolysis.  The water in the cavern by dissolving the calcites in the roof of that cave, then drips to make the stalactites.  The stalagmites are formed by the water from the stalactites on the ceiling piling up on the ground, and growing as more water drips. ]]> 2017-11-03 23:39:32 UTC https://padlet.com/20392472/slc333b4hm6z/wish/203491600 20392472 https://padlet.com/20392472/slc333b4hm6z/wish/203492156 An arete is a ridge between two valleys, which is caused by frost wedging, as well as abrasions, after two glaciers erode parallel valleys.  A horn is formed by a glacier erodes three or more aretes, which is formed by frost wedging, as well as effect from the glacier.   An U-shaped valley is formed by a glacier moving slowly, and creating this valley through its destructive path with the frost wedging and then melting, leaving the valley with steep sides behind.  A cirque is formed by frost wedging that then creates a semi circle valley, and is formed through frost wedging as well as abrasions that create the steep hills from the glacier. Hanging valleys are formed when two glaciers merge of different sizes, which creates the hanging valley that abruptly cuts off. A moraine is the leftover materials from when the glacier melts that uses abrasions to create new land forms.]]> 2017-11-03 23:52:23 UTC https://padlet.com/20392472/slc333b4hm6z/wish/203492156 20392472 https://padlet.com/20392472/slc333b4hm6z/wish/203493754 Creeps are downslope movement of particles on slopes that are covered in loose sediment, and is caused by many different types of weathering such as frost wedging and tree roots.  A landslide is when rocks and other particles are moving down a slope from abrasions.  Flows are formed by water and materials flowing down using abrasions, that causes destruction to the land in which it happened.  Slumps are formed by exfoliation that makes a part of the rock slide down the rock which creates a stair like look.  A fall is formed from abrasions and exfoliation that cause the fall to happen, in which causes a lot of destruction to the land]]> 2017-11-04 00:29:00 UTC https://padlet.com/20392472/slc333b4hm6z/wish/203493754
