Reasons why some have called global warming a hoax
By: Christyl Rivers
People are easily led to believe what they wish to believe. Conversely, they are mistrustful, and look for ulterior motives when someone tries to convince them of something new and fantastic. Climate change, (by humans) is new. Although it has been predicted for decades, evidence...
Impacts of ocean acidification on marine life
By: Dr Pandula Siribaddana
From the time of the industrial revolution, human interventions have made the atmospheric carbon dioxide (CO2) levels to rise exponentially. According to scientists, ocean being the largest pool of water on the surface of the earth, helped absorb almost quarter of such atmospheric CO2 and...
Impacts of ocean acidification on marine life
By: Frances Smith - 641219
Ocean acidification is the name given to the process by which the increase in carbon dioxide in the atmosphere, from the burning of fossil fuels, has caused more carbon dioxide to dissolve into the oceans and reduced the pH of the oceans, making them more...
The impact of ocean acidification on coral reefs
By: Jose Juan Gutierrez
Coral reefs are one of the most diverse marine ecosystems of the world. The coral reef ecosystem is formed by the calcifying organisms inhabiting it, such as corals and algae. Even though, coral reefs occupy a small percentage (0.1%) of the ocean, they...
Anthropogenic threats to coral reefs
By: Jose Juan Gutierrez
Coral reefs are one of the most diverse marine habitats in the world. The coral reef ecosystem is sometimes dubbed as the marine rain forest for its wide variety of marine life. It has been estimated that the coral reef ecosystem is the habitat of...

The tropics are defined as the area of the earth running from the Topic of Cancer in the north to the Tropic of Capricorn in the south. Within this area, there are many types of ecosystems and their associated soils. Soils will vary according to...
Compositional changes in metamorphic rocks
By: Retha Boswell
Metamorphic rocks are rocks that have been changed by heat, pressure, chemicals, or any combination thereof. The original rocks are transformed into new types of rocks. Igneous, sedimentary, and older metamorphic rocks can undergo metamorphism. The changes the rocks experience are in texture and composition...
Facts about chemical sedimentary rocks
By: Retha Boswell
Sedimentary rocks are created when particulates accumulate and are consolidated into rock. Chemical sedimentary rocks are a special type of sedimentary rock formed from chemical reactions. These rocks are made when materials dissolved in water precipitate and later harden with the other matter particles. This...
Causes of metamorphism
By: Retha Boswell
Metamorphism in geology is when one type of rock is transformed into another type of rock called a metamorphic rock. The word metamorphic comes from the Greek words meaning "change" and "form." There are two main factors that can cause the conversion: heat, pressure...
