“EVALUATE HOW PLATE TECTONICS THEORY HELPS OUR UNDERSTANDING OF THE DISTRIBUTON OF SEISMIC AND VOLCANIC EVENTS” In this essay I am going to look in detail at plate tectonic theory and how it can be used to explain seismic and volcanic events worldwide. However‚ I will also look at other potential causes of these events‚ and some evidence that does not follow the theory that all these events are caused by plate boundaries. I am going to look at a range of case studies from differing scales

shrinking pumice. This quest would eventually change the way scientists think about volcanoes-forever. One of the things (out of many) that he and his colleagues found out while on the road was that not only the rock was shrinking‚ the pores that make up the rock were shrinking as well. They think that this was due to the heating of the rock‚ and the molten rock’s surface tension. What the scientist found was how some volcanoes function on the inside. In past years‚ volcanologists believed that flowing lava

Is life possible on Mars? Geologists study the surface of both Mars and Earth by using interplanetary comparative analysis to further their understanding of the two planets. C.S Lewis‚ has a mind and imagination of his own when it comes to life on Mars‚ or as he calls it‚ Malacandra; A world where life exists‚ a world where humans can inhabit and explore this fantasy created by Lewis. Now‚ can these fantastic and unreal situations illustrated by Lewis be realistically possible today? There

It highlights the need for additional research using new technology to study the effects the ocean has on volcanoes and vice versa. New research is cited throughout this article; each study highlights an area in the Pacific Ocean. The Axial Seamount‚ off the Oregon coast‚ erupted in 2011 and again in 2015. The Chadwick study utilized hydrostatic pressure

you have highly destructive and explosive volcanoes often found along destructive plate boundaries because of increased pressure within the subduction zone. An example of this is the Philippines‚ which is situated above a destructive plate boundary and this leads to numerous and highly destructive volcanic eruptions. You also find volcanoes along constructive plate boundaries where the plates are moving apart and this is creating new lands and volcanoes as molten lava builds up‚ an example of this

GLOBAL WARMING What Is Global Warming? Global warming is the warming of the earth through carbon dioxide (CO2) being pumped into the atmosphere from tailpipes and smokestacks. Then the gases trap heat like the glass in a greenhouse. This is where the term the “greenhouse effect” came from. What’s Happening Scientists say that the barrier insulating the continental ice caps is melting. “The impacts of warming temperatures in Antarctica

The Tambora Volcano occurred in Europe in 1815 and did not end until four months later. In fact it spewed so much gases and rock into the air that‚ by the time it stopped erupting‚ it had shrunk by 4‚200 feet. To date‚ Mount Tambora has sent more particles into atmosphere than any other volcano in recorded history. .

hazards and secondary hazards. The primary hazards that can occur are pyroclastic flows‚ lava flows‚ tephra and poisonous gases. The secondary hazards include Lahars‚ volcanic landslides‚ tsunamis flooding and volcanic storms. The overall impact of volcanoes as a natural hazard varies greatly from one time and place to another. This is because it depends on the volcanic event‚ the population density of the surrounding area‚ the wealth of the area‚ the weather at the time and sometimes the culture of
