Atmosphere

Imagine a world filled by gases and the only way you could breath is with a mask. You may be thinking, well that only happens in the movies. NO! The carbon dioxide levels are rising at unprecedented rates and scientists believe this could actually happen... The strange part is that most scientists think it is us, the humans causing this problem. For decades now a major political and scientific topic has been climate change. The EPA defines climate change as “any significant change in the…

to the movement of moist air from the ocean to land, causing more evaporation. Also, the areas closer to the equator are generally warm because the energy from the sun directly reaches the equator without passing through any thick layers of the atmosphere. Another factor that contributes to climate change is the geography. For example, the Middle East and North Africa rarely receive rainfall because of deserts. Areas that contain deserts have little moisture; thus, decreasing the changes of rain…

fluctuations into account when they assert that we are currently experiencing unique conditions in Earth's history. Scientists have found only one variable to explain the relatively recent rapidity of global warming: an increase in greenhouse gases in the atmosphere due to human activity. By burning fossil fuels, humans have increased carbon dioxide in…

and probably significantly longer. In addition, the combustion of fossil fuels has also caused the atmospheric concentrations of sulfate aerosols to have increased. Greenhouse gases tend to warm the atmosphere and, in some regions, primarily in the northern hemisphere, aerosols, tend to cool the atmosphere. The weight of scientific evidence suggests that the observed changes in the earth’s climate are, at least in the part, due to human activities : climate models that take into account the…

Global warming is the term used to describe an increase in the average temperature of the Earth 's atmosphere and its oceans,a change that is believed to be changing the climate of earth ( Livescience.com ). It has been a global issue for a long time now. It has led to many global problems that are very dangerous to all people. Some historical background of global warming is , ever since the 1880’s earth 's temperature has been gradually increasing which is impacting the whole world and makes…

Mercury 's Surface Geology: according to the information gathered by the probes sent to Mercury, this planet has a surface that resembles in some manner the surface of our Moon, with craters and maria as its most prominent features. Furthermore, there are other structures that, albeit not as common as impact craters, make up the surface of Mercury, such as vents - that are thought to be the source for magma-carved valleys on Mercury - and irregular depressions named "hollows", probably generated…

EARTH, our beautiful world that supports US and other life form. That our god/’s, or whatever you as the reader believe in, created such beauty. But that beauty will come to a terminus, and not in the next 1 million years, 1 hundred thousand years and not even the next 1 thousand years. Earth will come to its final point in the next 1 hundred years because of global warming. Global Warming (greenhouse effect) is an official problem(even though our president said “It's a hoax created by the…

Earth-like planets, and characterizing particular planets of interest. With the advent of the extremely large telescope (ELT) era soon approaching, these two goals will become increasingly intertwined as better instruments give us the power to study the atmospheres of smaller, potentially habitable planets. In the meantime we can look at the brightest targets, typically Jupiter-sized planets in close-orbits, i.e. “hot Jupiters,” with current ground-based telescopes. I propose to develop a…

Exploration has many effects not only on organisms, but also the atmosphere. . By exploring for natural resources such as oil and gas, we contribute to global warming. Burning fossil fuels depletes the ozone layer and encourages global warming. Findings show “Air pollution near ground level, and acid precipitation, are already causing widespread injury to humans, forests, and crops” (Grossman & Bryner). Another impact on the atmosphere and on the elements of life can be seen in the uranium New…

Researchers have concluded so after studying the effects of severe temperatures and lifted carbon dioxide levels on maize, wheat and soybean production. More carbon dioxide or C02 in the atmosphere may allow more plant growth, however this effect is likely to be interrupted due to severe heat, researchers suggest. Crops are sensitive to heat around anthesis especially during the plant’s flowering stage. “At this stage, extreme temperatures…
