The Expeditions of Lewis and Clark America and I were astonished; President Jefferson doubled the size of the country with one purchase‚ the Louisiana Purchase. To add to the excitement‚ Meriwether Lewis asked me‚ a poor boat builder‚ to go along on the journey to the West. What was I going to do? Even though I made boats for a living‚ I had never explored past my little town in Virginia. After much contemplation‚ I thought‚ this is my time to explore the endless possibilities in what we Americans

“Volcanic and seismic events are major pieces of evidence towards proving that plate tectonics theory is valid’ Discuss the extent to which you agree with this statement (40 marks) The plate tectonics theory was made by a German named Alfred Wegener. He stated that a single continent existed about 300 million years ago named Pangaea and that it split into two continents of Laurasia in the north and Gondwanaland in the south. Today’s continents were formed by further splitting of the two masses

Volcanic eruptions can cause damage within hundreds of miles away. The volcano ash’s causes airplane engines to fail‚ destroys crops‚ contaminates water‚ and damages electronics and machinery. When the ash touch’s the ground‚ burying everything‚ sometimes even make’s buildings to collapse. Mount St. Helen’s produced more than 490 tons of ash that fell over some many miles. All volcanos are dangerous. They are all scattered all over the world and we don’t know when they are going to blow. The three

Guatemala is located in Central America and is bordered by Belize‚ El Salvador‚ Honduras‚ and Mexico. “ There‚ smoldering volcanoes meet swirling mists‚ and fertile coastal plains enfold lush green cloud forests” (Sheehan‚ 5). Now I will begin discussing the geography‚ climate‚ government‚ economy‚ and interesting facts on Guatemala. The geography in Guatemala varies greatly from volcanoes to lakes. The highlands take up about half of the country‚ while the Peten lowlands take about one third it. Guatemala

A hazard is a situation that poses a level of threat to life. Volcanoes exist all over the world and countless of them go over without us releasing because they are all of different magnitude. Only 10% of volcanoes are monitored around the world from which 90% of these are located in MEDC’S ( More Economically Developed Countries) Volcanoes can pose different type of hazards separating into primary and secondary. Primary being the ash and dust‚ lava flow‚ volcanic gases and pyroclastic flow. How

Its geologic history is a complicated tale of normal fractures in the Earth’s crust on its western edge to a more complex plot of basalt lava flows perhaps stemming from a hot plume of magma now beneath Yellowstone National Park. Coastal plains are stretches of lowland next to oceans that are separated from the interior by highland features such as mountains and plateaus. Often the plains are portions of the ocean floor built up

eruptions. Volcanic eruptions affect the climate of the earth in many ways (Zielinski et al 1997). Volcanic ash ejected during eruptions effect climate by reflecting solar rays back into space‚ and thus cooling the surface of the Earth. Another way volcanoes affect the Earth’s climate‚ is the emission of many different types of volcanic gasses. Volcanic gasses including CO2‚ H2O vapour‚ and different kinds of sulfur gasses such SO2 and H2S‚ affect the climate in very different ways (Robock 2000). CO2

Well that’s an answer no one has‚ but Italy doesn’t stop there. It has volcanoes‚ mountains‚ beaches‚ and subalpine lakes all in one country‚ which brings so much more diversity and culture to the appeal.
