A tsunami will reach land and hit the land with a massive amount of water and will topple over small structures, flip cars and move them like dust in the wind. The tsunami can go far into land up to about 8 miles. The tsunami is most likely caused by an earthquake out at sea.
Tsunamis are giant waves caused by undersea earthquakes, landslides or volcanic eruptions. The severity of their effects depends on a number of factors, namely the magnitude of the earthquake, landslide or volcanic eruption, along with its distance from shore. Small and undetectable tsunamis occur almost every day with little to no effect, but larger tsunamis have devastating effects to life and land that are often irreversible. The central effect of large tsunamis is massive loss of human life. With no time to escape, tsunamis cause near instant death, usually by drowning, but also by collapsing buildings, electrocution and more. Since 1850, tsunamis have killed more than 430,000 people. The March 2011 tsunami in Japan left a total of 18,550 people killed and/or missing. The severe flooding that occurs as a result of a tsunami also damages sewer systems, water supplies and soil. Stagnant and contaminated water leads to malaria and other diseases, causing illness, infection and death to spread rapidly. Soil becomes salinized from sea water and debris, effecting long-term yields of crops. The tall and fast-moving waves also damage property and permanently alter the landscape, sometimes wiping out entire islands. They destroy everything in their path, including buildings, trees, power lines, bridges, cars, boats and more, leaving behind them a mass of solid waste and debris that is almost impossible to clean up. They also destroy animal life, insects, plants and natural resources. Hazardous materials and toxic substances are also a concern, as asbestos, oil fuel and other industrial raw materials and chemicals often leak as a result of property damage.
They increased their sizes to rejuvenate the land. Before the war, everyone left their farms to go to the war. And once the war was over, the farms increased in size due to the high demand of resources needed to recover from the war.
Between 1931 and 1940 a ton of soil blew out of the central and southern great. It was a period of severe dust storms that greatly damaged the ecology and agriculture during the 1930s.
I think the correct answer from the choices listed above is the second option. An archaeologist studies the lives of early humans by examining artifacts. It studies the human activity by recovering and analyzing of material remains. Hope this answers the question. Have a nice day.
Cost- benefit analysis is the method that is mostly used by businessman to see whether they have taken correct decision or not.
Explanation:
Suppose a doctor has suggested two same type of medicine to the patient. One of the medicine is expensive and the other medicine is less expensive. But both the medicine will have same utility that is both will be used as a preventive measure for the sickness. One extra quality that the expensive medicine is having is that it will provide the patient to access to more application.
Using the cost benefit analysis it will be beneficial if the patient go for the cheaper medicine because the main aim of the patient is to cure the disease. Extra application is not required. The cheaper medicine will be budget friendly as well.
The cost-benefit analysis is basically known as the evaluation method because it helps the company to identify the best possible option that will give a good return on investment.
