Science behind It
Bryce Canyon National Park
The creation of these majestic and interesting hoodos all started at the bottom of a genormus lake, covering what we now call the Colorado Platue. The river feeding this ever growing lake, also allowed sediment to reach it and start piling up on the bottom. Over the years the lake began to dry out leaving behind a soggy, mushy pile of sediment. This too also began to dry out and harden, turning into the red filled rocks we see today. However it is not the creation of these rocks that influences millions of people around the world to visit Bryce Canyon, in an ironic way it's the destruction of these magnificent rocks. Throughout millions of years the rocks found here in Bryce Canyon National Park have taken on many different appearances. This through the destructive as well as artistic process of weathering and erosion has allowed the rocks to take on a unique shape. During the winter and spring the snow pack melts down causing the excess water to drain into the rock. Then when the water refreezes it cracks the rock, eventually when the crack becomes large enough the remaining piece of rock crashes to the ground. This process over millions of years has shaped the rocks into what we see today.
Arches National Park
Four things must happen or be ineffect for archces to form, the first of which the presence of the correct rock. In arches the majority of the rock formations are made of Estrada Sandstone. This sandstone we see today was once part of massive dessert covering southern Utah, as it hardened and was introduced to clay particles it created the correct rock type in which arches can form. Next you must crack the rock into parrel lines, you can do this through the the following process. Beneath all of this sandstone lays a layer of salt, which is crushed together by the rocks that reside above it. The pressure causes the salt to budge creating large long domes which in turn cracks the earth above it this creates a series of parrel lines. You must then have the correct amount of rain to allow the process of weathering and erosion to take place. When it rains the perception drains into the porus rock formations rotting the sandstone from the inside out. To much rain and the rock widles away to quickly. To little rain and the rock is never molded into the masterpieces we see today. Luckily arches national park receives eight to ten inches a year which may not seem like a lot, but is just enough to create the over 2,000 arches that dot the landscape within the park. Finally you must have very little sysmic activity, that would cause the rock formations to crumble to the ground, destroying these beautiful pieces of art.
2.How do the ever delicate arches of Arches National Park form?
3.Are there specific types of sandstone needed to create these rocks, and if so what is it?
4.Do different types of erosion such as wind, water, or sysmic creates a certain rock formation.
