... per hour. Such speed gives people sufficient time to escape the flow. The flow can reach dozens of kilometers from the crater. The dangers of lava being erupted by under-ice volcanoes have to do with creation of lahars – flows of mud, which are far-reaching and destructive, it can cause the increase of the water-levels, consequently creating floods ... because the ash from the eruption and the sulfuric acid formed from the emitted sulfur prevented the sun rays from reaching the Earth in sufficient amounts. What followed was an ice-age that lasted for approximately 1,800 years. The dro...

... hand, greatly increases the rate of soil erosion. Water plays an important role in soil erosion. When an area receives more water (in the form of rain, melting snow, or ice) than the ground can absorb, the excess water flows to the lowest level, carrying loose material with it. Gentle slopes are subject to sheet and rill erosion, in which the ... . Glaciers are important agents of erosion. Although a glacier moves slowly, it gradually removes all the loose material from the surface over which it travels, leaving bare rock surfaces when the ice melts. Wind is another active agent of erosi...

... near ground level. The pollution that humans create in the Earth's atmosphere could cause the surface to warm up to a dangerous degree. This could lead to melting of the polar ice caps and a major rise in sea level. But despite the harmful consequences, people continue to pollute the Earth's air. It has been measured that the concentration of carbon dioxide in ... ...

... the natural atmospheric greenhouse. This could warm the planet and have a huge effect on all forms of life. The global sea level could rise due to several factors including melting ice and glaciers. Rising sea levels could damage coastal regions through flooding and erosion. The climate of various regions could change too quickly for many plant and animal species to adjust ... ...

... of forest cover. It occurs through human interactions when deforested areas are prevented from naturally regenerating. Forests are capable of recovering from any destruction like fire, floods, volcanic eruptions and ice ages. Surprisingly, the recovery of forests that are destroyed through human implication recover faster than forests destroyed through natural causes. Deforestation varies according to the region. In tropical forests of ... ...
