Abstract:

Climate change is the shifting of the weather patterns and conditions characterized by the various indicators. It is also identified with the shifting of the average conditions of the weather and occurrence of extreme events. The climate of the Earth is affected by natural factors that externally induce changes to the cycle of the climate. The phenomenon of climate change is not a new thing. In fact, it has occurred many times in the historical periods. The various causes that trigger climate change are associated with various factors. There are two major contributory factors for climate change that includes 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...

1) Briefly explain how the Earth’s Moon formed, per the Nebula Hypothesis demonstrated in the online animation of our online course and discussed in our text book in the section of how our the solar system formed. (6 points). The moon formed with the origin of the solar system 5 billion years ago, when a large amount of gas and dust, a nebula, collapsed in of itself by the sheer force of gravity, forming what we call our nearest star, the sun (Chernicoff Whitney 2007, p. 15). The moon was formed as part of the process of particles Continue reading...

Abstract
The carbon cycle is a simple, but life sustaining process that organisms on Earth rely on to survive. The Earth’s atmosphere is comprised of carbon dioxide and methane. Plants cleanse the atmosphere of carbon dioxide, which would otherwise suffocate life. The carbon dioxide is used to create oxygen. As part of the cycle, carbon dioxide is then transferred into organic carbon, or absorbed into large bodies of water, contributing to water acidity and geo-erosion. From there, the carbon waits in the Earth’s mantle to be released naturally into the atmosphere through metamorphosis, or to be released Continue reading...

One major force that drives life on the planet is the lunar pull of the moon that causes tides. It is said that around 4.5 billion years ago, when our earth was still a molten mass, another molten mass was thrown into space, and this coalesced into what we know today as the moon. The earth then was already cooling, and had an ocean, but no veritable life was to be found in it. During this time, the moon was about half as distant from the earth as it is now, such that the lunar tides were more extreme 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...

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...

Introduction

It is currently apparent that most of what we observe on the surface of the earth and at shallow depths below the surface is related to one way or the other to plate tectonics. The plate tectonics theory started with an assumption and had to be proven with concrete evidences before being entirely accepted by the global scientific community. (Earth Observatory of Singapore, n.d. para. 1). Practically, all of the major land forming processes (exogenic or endogenic) that ensue on the earth's surface are related to plate tectonics. Seismic activity, volcanism, and mountain building are three of the most Continue reading...

Common Misconceptions for Seasonal Changes

Children and adults have misconceptions about why there are seasons on earth. This is reinforced by misconceptions about the earth’s shape, as demonstrated by thoughts that the earth is a “flat rectangle,” much less, that there are even two earths, one that is flat that people live on (some on the “top” and some on the “bottom”), and the other earth is actually a planet in the sky (American Psychological Association (APA), 2015). As absurd as these concepts may seem, even Harvard University graduates have misconceptions of a spherical earth and its relationship to the sun causing seasonal Continue reading...

Geology: Take Home Questions

1. Choose two additional Eh-pH diagrams for metals (e.g. Selenium) or other elements (e.g. Iodine) and write clear and concise answers about the mobility (bioavailability) or lack of mobility of the elements chosen, within the human body (you should include the Eh-pH diagrams for the systems chosen). Compare the Eh-pH diagrams you choose to the Eh-pH diagram below, as the figure provided is a good guide to determine which part(s) of your body a particular chemical species is mobile or immobile.
The element Selenium offers an example that is related to solid speciation and solution as impacted by Continue reading...
