Name plete this worksheet, see the instructions in the texthook (Chapter 6 Investigation). After completing. you will take a quiz with matching and multiple choice questions, which is posted in Moodle. (50 Points) Table 1. Landscape Features and Processes Volcanic Island Observations: In the white space around the figure below, write five observations about the physical appearance of different parts of the landscape. There is no right answer; just write some of the things you notice Rock Observations: On Table 2, use the descriptions provided on this worksheet to identify the type of igneous rock represented and determine the hazard potential associated with each rock type. Your instructor may provide you with hand samplesExplanation / Answer
The Ash and dust pumped out at the time or eruptions has proven to be the cause of mass extinctions in the past. The layer of dust, has the capacity to block the sunlight from reaching the Earth's surface and blocking the circulation of gases.
Moreover, the thick layer of ash causes problems in breathing and leads to suffocation
The molten ice along with huge amounts of steam and volatiles from within the Volcano lead to the disintegration of the rocks and soil above allowing a more plastic flow, easily flowing downslope into the streams.
These are high density fluids which engulfs the objects of obstruction and makes movement difficult.
These situations can only be dealt with my setting up a safe boundary zone beyond the limits of the Volcano. Being prepared for emergence evacuations and avoiding forest fires.
An efficient warning system would help save thousands of lives in such times.
Volcano-Related Hazard Evidence and Extent of Hazard Plumes of Steam: The steam generated and collected in the ground (erupts periodically) increases the geothermal gradient of the region and in-turn increases the temperature of the ground water. This has a local impact, where the biota in the near vicinity or close proximity is affected. It is majorly the burrowing animals but also the surface animals that are affected by it. Emission of Sulfur gas, from fumaroles or vents from the Volcano dome The emission of this harmful gas into the atmosphere has large scale impact due to circulation of gases in the atmosphere. Eruption of Volcanic ash and dustThe Ash and dust pumped out at the time or eruptions has proven to be the cause of mass extinctions in the past. The layer of dust, has the capacity to block the sunlight from reaching the Earth's surface and blocking the circulation of gases.
Moreover, the thick layer of ash causes problems in breathing and leads to suffocation
Muddlows (Lahars)The molten ice along with huge amounts of steam and volatiles from within the Volcano lead to the disintegration of the rocks and soil above allowing a more plastic flow, easily flowing downslope into the streams.
These are high density fluids which engulfs the objects of obstruction and makes movement difficult.
Crater formation The caving in of the volcanic dome can cause small scale earthquakes or deformations.Related Questions
