old is a stratovolcano. This volcano can be recognized even from a distance‚ due to its characteristic feature of a ’humpback’ mountain. Volcanoes are classified according to their shapes and Mount Vesuvius is a stratovolcano. * Volcanoes are grouped according to their shapes and Mount Vesuvius is a stratovolcano. Stratovolcano is a term given to volcanoes which have a pointed shape‚ shaped due to the deposits of volcanic ash‚ asphalt‚ hardened lava etc. * Mount Vesuvius is a volcano

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

article gives a description of these volcanic landforms. SHIELD VOLCANOES- These are characterised by gentle upper slopes. The slope varies from only 5 degrees to 10 degrees. The shield volcanoes are made up of mainly thin lava flows around central vent. The low viscosity lava (low silica content) travels down gently and as it cools down it creates less steeper lower slope. These are also found at the flanks of bigger volcanoes like Kilauea is situated on the Hawaiian shield volcano. STRATOVOLCANOES-

pushing towards each other‚ pushing the land upwards causing a mountain as well as an earthquake. 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

earth’s crust it causes cracks on the earth’s surface showing the magma. Mud slides are so powerful they can push rocks over or even the strong wall to collapse. 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.) In May 1980‚ following an earthquake Mount St. Helens erupted‚ triggering a massive landslide‚ which sent a plume of ash up into the

Searching for a Natural Hazard Free Zone The environment of the earth is very delicate. While the strenuous acts of human life impose harmful conditions to the earth’s environment‚ there are natural hazards that can impose harmful conditions for human life. At any moment there are natural hazards that can occur on the earth. While some hazards are more predictable than others‚ all have the potential to have disastrous outcomes. Like the catastrophic tsunami of the Indian Ocean in December

Jaesung Lee Geography 1 Professor Thomas Orf Chapter 14 Questions 1) The first evidence Wegner was able to find was the remarkable number of close affinities of geologic features on both sides of the Atlantic Ocean. He found the continental margins of the subequatorial portions of Africa and South America fit together with jigsaw-on-like precision. He also determined that the petrologic records on both sides of the Atlantic show many distributions- such as ancient coal deposits-that would
