Galapagos Drift Essay

When scientists entered the Galapagos Rift they found a variation in temperature that changed drastically. The data collected by researchers revealed temperatures fluctuating between 320F to 7500F, within a relatively short distance (NOAA). Not only high temperatures were registered, but a complete ecosystem was surrounded by a unique marine life capable of surviving the extreme conditions. Since then, not just the ocean floor has been part of the scientist 's investigation; but the marine habitat brought light on matters related to the origin and evolution of life on earth. During the transit of history, several volcanic features have been identified through the earth 's surface such as geysers and hot springs. In the deep ocean, a new …show more content…
Oceanic plates collide with continental plates, resulting in oceanic plate subduction creating volcanic activity most of the time near convergence zones. While, continental to continental plate collisions sculpts flat landscapes into a high chain of mountains, diverging oceanic floors create underwater ridges. Diverging plate boundaries spread plates due to the outward movement, contributed by the upwelling coming from forces originated in the mantle and asthenosphere. The water–magma (lava) interaction, and the diverging and converging forces help in the formation of underwater mountain chains called mid-ocean ridges (Christopherson and Birkeland 340, …show more content…
In the Southern part of Iceland were identified a hot spring known as the Great Geyser. The term gjose that means to erupt evolved from the old Icelandic language to identify the hydrothermal feature today. The exclusive appearance of geysers is limited to certain zones around the world. Countries such as Kamchatka (Russian Federation), New Zealand, Iceland, Japan and Chile are known for having intense volcanic activity. It would be faulty not to mention one of the most outstanding geyser zones located in North America belongs to the United States, the Yellowstone National Park. This park contains at least ten thousand thermal features, such as Mammoth Hot Springs, accounting for 300 hundred geysers in the park itself; recognized worldwide as the biggest of its kind. Geysers in the United States, specifically those located in the Yellowstone National Park, represent the 60% of that type of thermal features in the world
