Geophysicsand Geology Reflection
Wecommenced the discussion by analyzing frequency of hazards. Varioushazards rarely occur such as Tsunami, rising of water levels, slidingof rocks. Other hazards are frequent such as slope failure duringrainy season and flooding. Hazards effects were explores such asdestruction of buildings, crops, roads, deaths by factors such asTsunami, rockslides and rising waters. As discussed, a volcanooccurs when magma, rock fragments, ash and hot gases are releasedfrom beneath. It takes place in tectonic boundaries after a longtime. Magma is extremely hot and gases emitted are toxic inrespiration systems such as sulfur dioxide and carbon monoxide. Theyincapacitate free transportation of essential oxygen. Moreover, itleads to destruction of property and structures. Upon predictionnecessary measure are taken to avert likely effect. People should beevacuated and key sites relocated for continual performance.
Agroup was formed and assumed as an Emergency Preparedness agency. Wecame up with various ways of advising washing office on how to combathazards along the Pacific coast where communities lived in sandylocations and steep cliffs. Our report comprised of the following:sandy areas were susceptible to Tsunamis and raising water level.Rock slides in the cliffs and slopes failure along the rivers. Theareas were likely to face flooding. Various hazards have similarmitigation measure. An earthquake as a hazard was also discussed inthe class. An earthquake takes places when the ground shakes suddenlyand violently. Understanding these processes aid in anticipating thepossible effects likely to ensue. Measures are taken to prevent lossof life, property, fires and landslides. Anthropogenic factors suchas dumping waste underground which in some instances is addressed.Upon identification of the epicenter, if there are key features suchas dams or store building are relocated to eliminate dangers such asflooding and damage of property.
Frequencyof Tsunami and its effects was evaluated. As discussed, thou notcommon, when they strike they are highly disastrous. In the course,disturbances in the sea such as during earthquake lead to formationhigh waves in a series. Natural hazards in interlinked. Properlyunderstanding leads to adequate preparation such as building of highwalls and evacuation where necessary. They cause flooding viable landhard to inhabit and productivity of a given areas is reducesignificantly. Ample education to the coastal dwellers enables themto collaborate with the government in reducing the adverse effects.Residential houses are constructed a few meters away from the water.
Weanalyzed various hazards that are experienced in the cost. Thesecomprise of erosion, rockslides in the cliffs, slope slide, floodingamong others. The effects and mitigation measure was explored indepth. Wind, tides, waves and their action leading to formation ofcoastal landforms and dominate the coastal areas. The duration of thewinds and speed is a key determinant of the amount of erosion to takeplace. Features formed comprise of Tombolo, beach and spit. Highspeed winds leads to corrosion of coastal areas. Gravitationforces between the sun and the moon lead to formation of tides in theoceans. Depending of their height, they lead to flooding such asduring spring tide. Groins are erect to protect any longshoretransport. Seawalls and Beach nourishment enhance protection of thesea areas. High population leads to people residing in susceptibleareas to earthquakes. As describe by Keller Ed, growth in populationaffects sustainability balance and the earth system. It leads tohazardous processes that can be counteracted with scientificknowledge and values held by the people.
Hazards associated with rivers were analyzed and the associatedimpacts. These comprise of floods result due to riverbanks burst,slope slides and mudslides. They are frequent during rainy season. It leads to alluvial deposition in the land and warn peoples.Nevertheless, it has adverse effects. It leads to water contaminationand destruction of property. Many diseases arise and people succumb.In addition, it leads to alluvial deposition in the land and warnpeoples. Nevertheless, it has adverse effects. It leads to watercontamination and destruction of property. Dams, dykes and channelsare constructed to divert excessive water.
Ashort discussion about resources was help. Various answers were givento define resource. As concurred, a mineral refers to a chemicalcompound or element that is crystalline in natures. The groups gavethe reasoning concerning regulation of resources. The followingresults were obtained. It is imperative to regulate resources, theyare valuable and contribute enormous to the development of theeconomy, and they are nonrenewable. Various factors affectregulation. This comprise of the extraction cost, research cost andconflicts within the country of origin. Many countries have variedmineral but Canada leads contributing to a GDP of 15% such as diamondextraction.
Variouscommon energy sources were explored. They comprise of solar,electricity, woods, oil, gas and coals. They are used in home andindustries for purposes such as heating, cooking, drying among othervarious reasons. As discussed population threatens the sustainabilityof nonrenewable resources such as coals gas and oils. Resource areconstant and do not increase proportionally with population. Due toup-surging people ought to utilize mostly the nonrenewable resourcessuch as wind, hydropower and solar energy. These are cable ofsustaining the universe of a long period. The extinction ofnonrenewable resources should be high considered for continualutilization.
As debated, geologic resources are associated with heath. Theirpollution leads to ailments. Pollution occurs in waters, soil andair. Chemicals such as arsenic and radon are cariogenic and causebody problem such as bone and tissue aches. Human activities alsoaffect the quality of water resources such as eutrophication andchange in water pH. The study of geophysics and geology enablespeople to know the importance of environment. Clear environmenteliminate many diseases and prolongs life. Contamination affects thegeneral production of the lands and health of people in a givenareas.
Wateras a resource
Weevaluated water is an essential commodity in human life.Unfortunately, 97% is not consumable and is found in the seas. Freshwater comprises of a mere 3% and is not evenly distributed in theworld. Part of the fresh water is frozen in the poles and otherpercentage is underground water. Water circulates throughhydrological cycles, becomes purified and then back to the land andsea. All available sources need protection through legislation oflaw for sustainability despite the high population. Proper methods ofutilization such as drip method are a technology the preserve waterwastage.
Societyand Waste Resources
Asevaluated waste entails any product that is discarded due to its lowvalue or one that is unwanted. There are various ways of dealing withwaste. They comprise of decomposition of biodegradable materialssuch as foods remains. Organic manure is produced leading to highproduction after planting ensuring sustainability. Biodegradablematerials are also useful to the community after industrialrecycling. They are molten and molded to useful products such asplastic cups, basins, bowls and other components. Garbage is utilizedto produce biogas leading to less use of nonrenewable resources suchas oil and gas. All waste that is difficult to re-use of recycle areburied in a safe landfill and sealed such as radioactive waste.People should be advised on various methods of keep the environmentclear to eradicate some of the diseases.
