Tectonic processes active in the Cascadia subduction zone region include accretion, subduction, deep earthquakes, and active volcanism of the Cascades. This volcanism has included such notable eruptions as Mount Mazama (Crater Lake) about 7,500 years ago, Mount Meager about 2,350 years ago, and Mount St. Helens in 1980. Major cities affected by a disturbance in this subduction zone would include Vancouver and Victoria, British Columbia; Seattle, Washington; and Portland, Oregon. The two tectonic plates involved in the subduction process at the convergent fault line are the Juan de Fuca plate and the North American plate. The Juan De Fuca plate being the denser oceanic plate is being subducted under the continental North American plate.
Also, there are cut banks where larger sediments are eroded due to the stronger currents. The Missoula flood was caused by deglaciation of glacial lake Missoula at the end of the previous ice age when the dams broke. It flooded Eastern Washington, specifically where the Spokane river is located. Glacial outburst flood deposits dumped much gravel and eroded basalt rocks into what we see today, such as the Bowl and the Pitcher. The flooding also brought up thick loess on either side of the river.
This effect causes very heavy rainfall, which causes the formation of the Chattahoochee and Savannah Rivers. Many believe that the region id Georgia’s most visually stunning geographic region, which is also the cause for tourism, which also has become a big industry in the region. In the end, the Blue Region is my personal favorite region out of them
Monument Valley is the region of the Colorado Plateau characterized by a cluster of vast sandstone buttes and Antelope Canyon is a slot canyon was formed by erosion of Navajo Sandstone primarily due to flash flooding and secondarily due to other sub-aerial processes. When we entered in these areas, we saw the marvelous spectacle
West Virginia Introduction Imagine a great place where great mountains tower high above your head. Imagine that same place with vast valleys filled with green grass and beautiful blue rivers that shine out at you as you are put in a trance by their beauty. Imagine that land with the warm yellow sun beating down on your back as you take a long relaxing hike. West Virginia 's hard earned attractions, many exciting features, and interesting geography attract thousands of tourists to "The Mountain State" every single year. The Creation of West Virginia West Virginia has had many attempts at statehood, under the leadership of many different people and for many different reasons.
Jewel Cave is located in the Black Hills of South Dakota. The Black Hills were formed during the Tertiary Lamanide Oroginy. (See Figure 2 and 7). The Black Hills are doubly asymmetrical anticlines that are plunging to form a dome. Two rock types are from the Tertiary and the Quaternary period and are starting to intrude into the older rock types.
Minerals in diabase are magnetite, olivine, ilmenite, hornblende, biotite, and chlorite. Diabase is an igneous rock that forms from magma from a volcano eruption. The rock can form in the ocean mostly but sometimes can form near the beach as well. 159001444 Museum Assignment 2 1) These minerals are found mostly in the following New Jersey towns: Franklin, Ogdensburg, and Patterson. These
Following up the information about the formation and deadliness of volcanoes is an example of a volcano, Mt.Tambora, one of the deadliest volcanoes ever. This volcano erupted over 200 years ago, but made a big impact all around the world. It erupted for three months in total. You could hear the explosions from over 1,000 miles away(Lassieur 4). This covered things in lava and was very hard to recover because the lava cools and hardens turning it into something as hard as bedrock(Lassieur 3).
The Axial Seamount is located next to the Juan de Fuca Ridge, but on the Juan de Fuca Plate. The Juan de Fuca Ridge is a mid-ocean ridge. The Axial Seamount was formed by the many earthquakes that kept happening in that area. In a three day span of all the earthquakes, the sea floor dropped over 2.4 m. They can also be created by divergent bonds by the sea spreading apart. Axial Seamounts are submarine volcanoes.
Fracking has had such an impact on the environment causing earthquakes, water supply damage, and polluting the air. (Background Information) Fracking is also known as hydraulic fracturing. Hydraulic fracking is a method in which natural gas is extracted. Shale formations underneath are injected with a mixture of chemicals and water at a high pressure in order to break up shale rock. In “Does Fracking Cause Earthquakes?” Richard Bennett, from the Best Review, explains how once the rock is fractured, it releases shale gas or natural gas.
