one big one and now we have many various oceans around the world. 2) How did volcanoes affect the origins of the seas? -Volcanoes affected the origins of the seas because many gasses are released during a volcantic eruption including water vapor. Water vapor was the main contributor to where the primary ocean waters originated from. This is because the water vapor condensates after being gassed out of the volcanoes‚ once the condensation occurs then precipitation is created. 3) Describe the hydrologic

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

The plates are pieces of land that make up the outer crust‚ these could move together‚ move apart or move alongside each other resulting in mountains‚ volcanoes and earthquakes‚ this happens deep below the surface and as the earth is spinning and moving‚ the boundaries move also over millions of years. Tectonics: There are four different types of plate boundaries; constructive‚ collision‚ destructive

Due to its history of recent activity and nearby population‚ Mount Etna has been designated a Decade Volcano by the United Nations. From about 35‚000 to 15‚000 years ago‚ Etna experienced some highly explosive eruptions‚ generating large pyroclastic

With reference to two volcanic events that you have studies from contrasting areas of the world‚ compare the ways in which volcanoes and their impacts have been managed. (10 marks) The TOP TIP for what the Q means? Contrasting areas = Compare = Managing impacts of volcanoes = Candidate’s Answer Mt Pinatubo volcano in the Philippines erupted in June 1991. [First volcano] Its eruption consisted of many pyroclastic flows and the large high ash clouds‚ and had severely negative impacts

Here‚ we can observe that the trenches (yellow line) are parallel to the volcanoes (red dots). You can almost draw a straight line to connect all the volcanoes. Moreover‚ the data above is evidence of the presence of subduction zones wherein the collision of two plate boundaries causes the denser plate to sink below the less dense plate into the asthenosphere.

Avalanches are sometimes made from when a volcano erupts. Volcanoes can be very dangerous in many ways. Some things volcanoes do are good. If the volcano is an underwater volcano‚ they erupt and form islands. The time when Mount Pinatubo erupted during 90’s‚ I was not able to comprehend why do ashes fall‚ and do not realize the effects of

Of the 13 active volcanoes that are a part of the Cascade Range‚ Mount St. Helens is one of the more active volcanoes with its last major eruption occurring in May 1980 (Lutgens‚ 2012.)
