On Earth, volcanic eruptions trigger the carbon cycle that accounts for the eventual concentration of calcium carbonate wherever water once existed. On Mars, the absence of calcium carbonate and, even more importantly, the presence of jarosite suggests that the element sulfur may have played a comparable role to that of carbon on Earth. Specifically, Martian volcanoes apparently ejected vast quantities of sulfur dioxide (instead of carbon dioxide released in volcanoes on this planet) where it was eventually dissolved in Martian oceans to form silicates and sulfites including calcium sulfite. At the same time, the presence of calcium sulfite would also have inhibited the formation of carbonates like limestone.
Additionally, this recent observation also offers a logical explanation for how a planet like Mars which is presently far too cold to support...
Evolution be Taught in Schools? Introduction / Thesis (Part One) The debate between those that believe in creationism -- or "intelligent design," a refined offshoot of the creationism theory -- and those who believe in the science of evolution, spilled over into the schools in the United States many years ago. Conservative Christians and others who are in denial vis-a-vis Charles Darwin's research and theory argue that at the very least
evolution and creationism. Evolution is usually held responsible for inducing immorality among its followers. This paper discusses the impact of believing in evolution on the behavior of student by describing both the evolutionary theory and its various effects. EVOLUTION AND STUDENT BEHAVIOR It is the belief about an individual's origins that sparks a debate evolution and creation. This is because not only does the belief about origins (and the consequent debate)
Evolution "Creational critics often charge that evolution cannot be tested, and therefore cannot be viewed as properly scientific subject at all. This claim is rhetorical nonsense" (Stephen Jay Gould). Human life is both sacred and mysterious. From time before recorded history, human beings, both scientific and religious have tried to determine what it is exactly that gives life and by extension, can take life away. In ancient times, most people believed that
EVOLUTION What is evolutionary theory and what are causes of evolution and the evidence of evolution? The term 'evolution' evokes varied connotations. In simple and direct terms it is a process of change or development over a long period of time. Defined so, evolution can refer to any phenomena-- evolution of universe, evolution of human culture etc. -- that change over a period of time. However, in common parlance, evolution refers to
Nonetheless, this does not make philosophy any less important in the field. Philosophy today can be seen as a manifestation of the workings of the human mind, while psychology studies the mind itself. Philosophy is therefore a very important aspect in helping the psychologist understand the human mind. Philosophy is indeed responsible for the birth of psychology as a discipline in itself, as mentioned. While the early philosophers, Socrates, Plato and
Evolution of Cognitive Psychology A discipline in the field of psychology, cognitive psychology examines the way people process information. This field achieves this goal by examining how humans treat information that they receive through stimuli and how their treatment of information contributes to certain responses. Therefore, the professionals in this field generally study people's internal processes like perception, language, attention, thinking, and memory. Cognitive psychology is based on the concept that
