North and Tropical Atlantic Ocean causes climate change in Antarctica The news “North and Tropical Atlantic Ocean Bringing Climate Change to Antarctica” dated 22 January 2014 reveals that distant regional conditions have a role in changing the Antarctic climate. The study reveals that when the data of North and Tropical Atlantic’s Sea Surface Temperature over the last three decades was compared with the changes in Antarctic climate, it was found that there is a correlation. Warming in Atlantic’s waters is followed by changes in sea-level pressure in the Antarctic’s Amundsen Sea. This results in the redistribution of sea ice between Antarctic’s Ross and Amundsen-Bellingshausen-Weddell Seas. Thus, the study identifies a correlation between Atlantic and Antarctic climate changes.
The study reveals that distant regional conditions can have long term impact in changing the climate in Antarctic, thus prompting scientists to look beyond Pacific Ocean and El Nino. Admittedly, Antarctic region is a very important agent in global climate, absorbing a lot of heat and carbon dioxide. The sea ice around the continent is important for the proper exchange of energy between the Sun and the Earth. In fact, recent climate change and human activity were considered as the culprit behind the climate change in Arctic. However, the new study reveals that there are many more factors to be identified. For example, while there is a decline in Arctic sea ice, there is no decline in Antarctic sea ice. Thus, the study shows that there are more culprits other than greenhouse gases and holes in ozone layer.

.... The risk of eruption is typically communicated to the people through regular media channels depending on the urgency of the situation. d. What are some of the conditions that are specific to each of these volcanoes? At the Montserrat Volcano Observatory it is typically reported that the conditions would involve large areas being covered in ash as well as pyroclastic lava flows. At the Yellowstone caldera any number of things can transpire such as massive lava flows, massive eruptions that will spew ash into the atmosphere, gas, powerful explosions and more.

...and possibly an indication of low seal availability. Seals appear to be pupping under sea ice because of altered sea ice conditions and storm events that rafted thinner ice. The long-term consequences for polar bears are unknown, but a reduction in energy intake is likely to affect many aspects of the bear's ecology. Some den areas may be abandoned completely. Recently, a new study in Alaska revealed that polar bear dens on the pack ice declined from 62% between 1985 and 1994 to 37% between 1998 and 2004 (Gagnon and Gough, 2005). This was probably a result of declines in the amount of stable old ice; increases in unconsolidated ice; lengthening of the ice-free period, which reduced the availability and quality of pack...

...Geology Earth itself has had its share of unfathomable mysteries and the universe with all the heavenly bodies occupying it appears vast in mystery and beauty. For one, the exhibition via the Cullman Hall of the Universe is particularly striking. Viewers like me are chiefly left with an impression that universe indeed is ever-expanding. At that moment, I was brought to ponder about the size of God who is behind such an incredible idea which reflects the great astrophysical value of matters in the outer space. During this stage, the sight of the exhibits drew me to the interest of imagining how quantum particles could have possibly been of the evolution process of the cosmic materials comprising the universe. Similarly,...

...The history and arguments about the origin of the earth and evolution have given many scientists sleepless nights trying to unearth what might have actually happened long before we came into being. Scientist hope that one day the matter will be put to rest by providing evidence and be able to prove to the world beyond any reasonable doubt that certain specific activities took place. Their progress is mainly centered on the rocks which are the source of their evidence. The discovery of rocks which will provide the evidence and chronological evidence was a great milestone. Religious divide on the other hand seem to disagree with idea of millions of years and squeeze it to before six days of creation (Dawkins. 2012). Having gone... history and...

... of the Saddle Mountain Geology A close analysis of the rock presented highlights that it is Miocene basalt. Geological research has indicated that the Saddle Mountains formed in the Miocene and a post Miocene age when the uplifting of the Miocene volcanic rocks took place. The uplifting took place in a manner that saw the folding of the volcanic rocks in a relative design to the synclinal valleys. Many geologists have highlighted that the quaternary normal faults are the description for the faulting that resulted. This led to the formation of class B structures that characterize the Saddle Mountains. It is in these mountains that the described rock was found (‘Washington Geologic Newsletter’ 56) According to further research... , there is...

The trail winds between substantial, vertical dividers of sandstone and into recovered earth pits. The trek ought to take around an hour round excursion and include a couple of spots troublesome/outlandish for elderly and/or disabled persons to get to. Along the trail are a few quits highlighting earth mining and dinosaur, mammal, birds, creepy crawly and invertebrate tracks and follow, and a few dividers loaded with plant impressions from the tree-lined delta-natures turf (trail). There are footprints at Triceratops Trail that vary from those at Dinosaur Ridge....

Geology: Case study

...Geology Case study Fracking as a cause of Earthquakes Earthquakes, also known as tremors, refer to thecreation of seismic waves occurring mainly due to the sudden release of energy in the earth’s crust. Many factors have been said to cause earthquakes, however for environmentalists, hydraulic fracturing, or fracking is the greatest cause. However, such an opinion is subject to debate and can only be justified through proof. Based on such a perspective, this paper addresses the aspect that despite the fact that fracking indeed causes earthquakes, it does so to limited extent as compared to other causes such as reservoir-filling. Fracking, which is also the hydraulic fracturing process used to access oil and gas from...

...Geology assignment Imagine you pour water on the sedimentary rock sand sandstone. What happen to the water over time? The water will flows into the pore spaces between the sand grains 2. Approximately how big are pore spaces in sediments or rock? About the size of a rice 3. Two student are discussing the best analogy for most ground water Student I: I think most ground water is like water in large underground holes or caves. When we look at water on Earth’s surfaces, it gathers in big pools, so I think it would be the same underground. Besides, there is not enough room in rocks for water to fit. Student II: I think most groundwater is like water in sponges. Water fills in lots of very small empty spaces within certain...
