ENVIRONMENTAL POLLUTION Efforts to improve the standard of living for humans--through the control of nature and the development of new products--have also resulted in the pollution‚ or contamination‚ of the environment. Much of the world’s air‚ water‚ and land is now partially poisoned by chemical wastes. Some places have become uninhabitable. This pollution exposes people all around the globe to new risks from disease. Many species of plants and animals have become endangered or are now extinct

volcanic hazards? (40 marks) A hazard is a situation that poses a level of threat to life‚ health‚ property‚ or the environment. Therefore‚ in this case a volcanic hazard is the threat posed from natural volcanic processes towards the populations and the environment. The extent of volcanic hazards can vary due to two factors; physical factors such as the type of volcano and human factors such as the population density in the area. Volcanic hazards can also be placed into two phases: primary hazards such

Analyse the factors that cause differences in the hazards caused by volcanoes around the world (40 marks) A hazard is defined as something which has the potential to kill or cause harm. However a hazard is only a risk to people if they are exposed to it. This is when a hazard can cause disasters. For example‚ a volcano is only a hazard if the population comes in contact with the consequences of its activity. Hazards and their likeliness to become disasters can depend on many different factors‚ for

To what extent can planning and preparedness mitigate the effects of volcanic hazards? A hazard is a situation that poses a level of threat to life‚ health‚ property‚ or environment. There is a very big difference that helps prepare for a volcanic hazard and that is whether you are in a MEDC or a LEDC. In a MEDC monitoring volcanic zones and potential hazards is an option many LEDC’s don’t have. In Italy at Mt Etna they have Geochemical monitoring programs currently run by INGV which focus on the

effects of volcanic hazards? (40 marks) Volcanic activity happens across the surface of the globe and naturally hazards occur too. A hazard is a situation that poses a level of threat to life‚ health‚ property‚ or environment. It is easy to locate volcanoes‚ but it is very difficult to predict exactly when activity will take place‚ particularly a major eruption‚ this makes it difficult to prepare or plan for one. There is a very big difference that helps prepare for a volcanic hazard and that is whether

To what extent can preparedness and planning mitigate the effects of volcanic hazards? (40 marks) A volcanic hazard is anything that can cause a threat to human life‚ infrastructure or nature as a result of volcanic activity. There are methods to lessen the effects of volcanic hazards to a certain extent through planning and preparation. Common volcanic hazards include: Pyroclastic flows‚ Ash clouds and mudslides. Pyroclastic flows are high-density mixtures of hot‚ dry rock fragments and hot gases

It is an amorphous and a blank image to the students as they were earlier used to theory courses with prescribed text books and lab works that need to be carried out in the laboratory. A Project work is fortitude of common goal and group approach. Each passing year the engineering scholars are assigned project

To what extent can preparedness and planning mitigate the effects of Volcanic Hazards (40 marks) More than 500 Million people live within 50 miles of a volcano‚ the potential therefore exists for major loss of life and damage to property and infrastructure‚ particularly when urban areas are situated in close proximity. Mitigation of such losses can be achieved through careful preparedness and planning. Preparedness is the process of ensuring that an organization has complied with the preventive
