Free Essays on Gases to Get Inspired & Learn by Example

The Earth's atmosphere consists essentially of nitrogen (78%) and oxygen (21%). 1% mostly belongs to argon and other substances. These gases are transparent to sunlight passing through them and heat the Earth's surface. Warm earth and oceans in their turn heat the lower part of the atmosphere. Part of this heat re-enters the space. If this is all over, the average temperature on Earth would not exceed -18 ° C instead of the current 15 ° C.
The temperature at the surface of the Earth is the result of an equilibrium established between radiation coming from the sun and the energy Continue reading...

Most people rely on the research conducted by the scientists when explaining a state of nature. However, there are some individuals who have come out in the open to challenge the facts presented. The scientists associate the climate changes denial with the fossil fuels. However, the different human activities result to global warming, which in turn destroys the ozone layer. The destruction of the ozone layer predisposes the living things to many challenges and diseases, for instance, the skin cancer due to the direct rays of the sun. Nonetheless, different groups have differed on the forces behind the global Continue reading...

Abstract

John Dalton’s interest in meteorology led him to the breakthrough discovery which he has proposed in his Atomic Theory.
John Dalton was a chemist from the England and a meteorologist and physicist. John Dalton is well known for his contribution towards the atomic theory. On the basis of the atomic theory, he is known to be the father of the modern atomic theory. John Dalton was also involved in forecasting the weather. He was among those scientists who liked to place the instruments at home which Continue reading...

Climate change was the term used frequently in research articles for over forty years before the term global warming was employed. In 1956, Gilbert N. Plass used the term climatic change in his paper, while it was only in 1975 that the term global warming was used by the author Wallace Broecker. In mass media, global warming and climate change are frequently exchangeable nowadays even though they have dissimilar scientific descriptions.
Global warming pertains to the elevation in the world’s typical exterior temperature from the time of the Industrial Revolution. It is principally attributable to the discharge of Continue reading...

Introduction

Climate change is a natural phenomenon that takes place cyclically every few hundred thousand years. However, unlike the past occurrences of climate change, what sets apart the climactic change of this century is that it is more of an outcome of human activities. Owing to the callousness of human beings and total disregard to the environment, the amount of greenhouse gases, including Methane, CO, CO2, water vapor and Ozone, has increased in the atmosphere considerably, leading to global warming (TNC, 2015). The increased temperature of the earth has already made noticeable impacts, including torrential downpours, melting of mountain glaciers, Continue reading...

Global warming – or climate change as it is now more commonly referred to – has emerged as a hot topic issue in the past thirty years. Old hypotheses are constantly Continue reading...

Introduction

There is real evidence that human activity contributes to the accumulation of "greenhouse gases" in the atmosphere, which leads to a gradual increase in air temperature on a global scale. In particular, carbon dioxide (carbon dioxide) produced by burning fossil fuels, electricity or cutting and burning of forests. The process of accumulation of greenhouse gases, including methane, nitrous oxide and other, went so far that the planet faces a real risk of massive and potentially devastating effects. The effect of greenhouse gases on global warming is, in my opinion, the most important environmental issue facing the world today (Ramanathan, Continue reading...

What chemicals do Nitrosococcus oceani and Nitrosopumilus maritimus consume from their ocean environment?  How does the abundance of these chemicals influence their success and abundance?  What is the relationship between nutrient availability and natural selection, in general?
Nitrosococcus oceani and Nitrosopumilus maritimus are examples of single celled organisms which are part of the kingdom Archaea. They are totally separated from the bacteria and other organisms (Stewart, n.d.). They are very important for some of the natural processes in the environment especially for the nitrogen and methane cycle. They are also a major part of the biological and biomass processes Continue reading...

Introduction

Enhancing the functionality and working capacity of the car engine remains one of the biggest challenges that car owners and enthusiast alike face. Most car owners are on the verge of looking for ways of making their cars run faster, smoother, and cover more miles per gallon whenever they fill up. In fact, most car owners can swap their car engines for better ones or even add a turbocharger to their system in order to boost the functionality. Nevertheless, replacing or upgrading the exhaust system of a car is one of the most reliable ways of enhancing the efficiency Continue reading...

Volcanic Hazards

A volcano is a sudden breakdown of magma in the mountain or hill from the depth of Earth’s surface. More than 500 active volcanoes are found in the world (John Watson, 1997).The volcanic hazard is the danger of life or material because of the volcanic eruption. This paper is divided into four sections. The first section discusses the volcanic hazards. The second section deliberates the hazards which are directly linked to volcanic eruptions. The third section highlights the hazards which are indirectly linked to volcano. The fourth section concludes the paper.
The common volcanic hazards are lava, Continue reading...
