    supported theories argue that life came to existence inside hydrothermal vents, hydrothermal impact crater-lakes, and terrestrial, anoxic geothermal vents; these theories claim that life originated inside Earth and this notion is well supported. The correct theory must be able account for the fact that life emerged roughly 3.8 billion years ago, the short time gap between the formation of oceans and the origin of life, and the chemical composition of modern day cells (Baross and Hoffman, 1985).…

    Galápagos Rift revealed hydrothermal vents, and along with it new and unknown creatures that somehow has survived in very harsh conditions. Hydrothermal vents are most commonly found along mid-oceanic ridges, such as the Mid-Atlantic Ridge and the Galápagos Rift. Seawater seeping deep into the Earth’s crust through fissures and cracks in the seafloor is heated by magma beneath the surface, causing the water to boil and rise back up to the surface. As it rises, the water dissolves and…

    Scientists today know mostly everything there is to know about life on prebiotic Earth approximately four billion years ago, yet, they still do not possess the answer as to how life came to be from inorganic matter. Many question how life could have risen from non-living materials and become as complex as it is. Nobody knows for certain how the transition from inorganic matter to life occurred, however, there are several theories made to explain this transition (i.e. Clay theory, Primordial Soup…

    Earth began, the newest clue is the discovery of hydrothermal vents. These vents are deeply immersed in the oceans that harbour rich ecosystems, the energy source from mid-ocean-ridge volcanism. Additionally the vents can reach high temperatures up to 407C (Sander, 2011). and can reach temperatures up to 121°C (Martin et al., 2008). Many researchers’ theories pertaining to the origins of life stem from a series of specific chemical reactions, as well as Earth’s atmosphere, which might have…

    of volcanoes on the ocean floor vary in every way which only makes them more mysterious and fascinating. The first discovery of a hydrothermal vent was aboard a 3-person submersible named Alvin in 1977 at the Galapagos Rift (WHOI, 2004). This vent was a discovery of warm fluids mixing with cold ocean water rising from the ocean floor crust (WHOI, 2004). “In 1979, a second hydrothermal system was discovered along the East Pacific Rise” (WHOI,2004). This discovery was much hotter than the first…

    organic molecules, but also for the formation of oligomers and polymers. The experiments involved in testing the hypothesis was one that Stanley Miller did , in the experiment he mixed methane, ammonia, and hydrogen to form basic monomers. The reasoning the scientist gave to support their theory was the first cellular life forms may have evolved inside so-called black smokers at seafloor spreading zones, in the deep sea. Deep Sea Vent Hypothesis: The scientist involved in the hypothesis was…

    A deep-sea hydrothermal vent is one of the harshest places to live on earth. This is due to the pitch darkness, heavy metals, extreme acidity, poison gas and the enormous pressure. Sunlight penetrates no further than a few hundred feet down which means the deep-sea floor is as dark as a deep cave. There are no plants due to no sunlight and all the vent life belong to the animal kingdom. Due to there being no plants there is no photosynthesis. These organisms rely on a process called…

    different aspects in the world of geology. Something that I want to focus on are hydrothermal vents. Hydrothermal vents are like chimney shaped hot springs that are located on the ocean floor. Hydrothermal vents were first discovered in 1977 near the Galapagos Islands in the eastern Pacific. Scientists exploring the area along the mid-oceanic ridge had noticed drastic temperature changes in their data. With the help of ALVIN, a research deep sea submersible, they discovered vents that were…

    Hydrothermal vents interact with sea water that percolates through fissures located on the sea floor to be expulse later after being heated. Same as geysers that can undergo same process with fresh water. This statement does not mean that geysers do not occur in the bottom of the sea. Nevertheless, the spectacle can be appreciated by the naked eye when geysers are located on the surface. Most geysers erupt fountains of hot water and steam intermittently or episodically. As mentioned at the…

    These hydrothermal vents, sometimes called “black smokers” because they secrete dark water, but most importantly the water that comes from these vents reach a temperature of about 720 degrees Fahrenheit. The mix of the very high and very low temperature waters make it the best place for these crabs can live. They cannot survive long outside of their “thermal envelope” because they can freeze to death.…
