Carboniferous

stethacanthus evolved from these conditions. This shark lived in warm shallow seas and was 2 feet in length. The males had flat topped dorsal fins and enlarged scale on the top of their heads either for courtship purposes or offering protection. In the Carboniferous period many sharks underwent a very large adaptive radiation, which created the golden age of sharks approximately 250 million years…

The Possibilities of a Climate Crisis In the book, Truth to Power by Al Gore, Gore asks three questions, “Must we change?”, “Can we change?”, “Will we change?” (Gore 10). Gore is certain that the answers to the first two questions are yes. Regarding the last question, Gore seems optimistic that we can change, but only if we stay committed to our global consensus (Gore 10). Based on Al Gore’s findings, he believes that infectious diseases through insects, catastrophic storms, and the impacts on…

With the whirlwind of controversy revolving around the current issue of the release of carboniferous emissions, greenhouse emissions, and the rapid increase in global temperature it is very imperative to pursue other means of efficient, clean , and renewable resources before we reach the state of decline. In other words we should sway away from the abundant usage of fossil fuels and recognize the benefits of other energy sources that will help economically and environmentally preserve the…

years prior. (Creatures of land and water are vertebrates that live some portion of their lives ashore and some portion of their lives in water.)The Mississippian and Pennsylvanian times of Paleozoic time have been known as the Coal Ages, or the Carboniferous periods. Amid these periods, the Earth's atmosphere was hot and damp. The greater part of its landmasses were low, intensely forested, swampy ranges. As trees and plants kicked the bucket, they got to be covered in swampy dregs. Over drawn…

The Eurypterids had great diversity and included various forms of gigantism. Large predatory pterygotids (Eurypterina) became longer in the Siluro-Devonian while sweep feeding Hibbertoperids (Stylonurina) exhibited greater mass from Carboniferous to end Permian (Lamsdell et al, 2010). Various studies were done to determine whether the abiotic environmental factors or the biotic factors such as competition was behind these evolutionary traits. It has been suggested that pterygoids incorporated…

Earth has experienced variations in climate throughout history. Several cycles of glacial advance and retreat (specifically the Permian, Carboniferous, Cambrian and Pre-cambrian glaciations) demonstrate natural climate fluctuation. These fluctuations can be attributed to deviations in the Earth 's orbit; the amount of solar energy received by Earth differing as a result of this. Current temperature trends display an aberrant rate of increase in global lower-atmospheric temperatures. This…

Global warming is the warming near the earth 's surface that results when the earth 's atmosphere traps the sun 's heat. The earth is getting warmer. The changes are small, so far, but they are expected to grow and speed up. This year we are experiencing record breaking high temperatures all over the world, this is due to global warming. Within the next fifty to one hundred years, the earth may be hotter than it has been in the past million years. As oceans warm and glaciers melt, land and…

The industrial revolution brought forth a myriad of technological innovations which helped to improve the world, but it also introduced new air pollutants via the combustion of coal underpinning the new technologies. Acid rain caused by carbon dioxide and particulate pollution released in combustion destroyed fragile habitats and introduced irreparable damage to the earth. While the new technologies helped to improve the everyday lives of numerous people, they also caused an exponential growth…

These energy sources were formed during what was called the Carboniferous period which gets its name from carbon, the basic element in fossil fuels (Energy Quest 2012). Different variations of fossil fuels were created based on what combination of plant and animal debris were present, as well as the amount of pressure…

Gas Exchange + Transport Pulmonary circulation: circulation from heart to lungs Systemic circulation: circulation from lungs to organs Gas exchange is the movement of oxygen from the lungs to the blood and the movement of carbon dioxide from the blood to the lungs. This exchange occurs in the capillaries, which are microscopic vessels in the lungs. In humans, nutrients and oxygen are transferred through the bloodstream. Cells can’t rely solely on diffusion, so this transport system is important…
