Fossil

Fossils are the preserved remains or traces of animals, plants, and other organisms from the remote past. The remains were once the hard parts of an organism, like bones and shells,however under special circumstances, soft tissues have also fossilised. There are different types of fossils because remains can be preserved in different ways. Trace Fossils – These are the preserved evidence of an animal’s activity or behavior, rather than the remains of the animal itself. Examples of trace fossils that have been found include: trilobite tracks marine invertebrate burrows ichthyosaur coprolites (fossilised excretion) Fossils with some organic material preserved – During Fossilisation, animal and plant remains can experience a variety of physical…

The fossil record; what is it? First of all we need to know what a fossil is. A fossil is evidence of a life from years ago which has been preserved in some way. This includes impressions or remains of an organism embedded in strata (Biology Online, 2011). Now that you have an idea of what fossils are, what is the fossil record? The fossil record provides information about the history of life on earth through the placement of fossils within the rock strata. The fossil record also shows how a…

many rely on fossil fuels to help with daily necessities such as delivering electricity, powering vehicles, and heating their homes. Fossil fuels have been widely used since the Industrial Revolution. Since then, the use of fossil fuels has greatly grown. Fossil fuels are any naturally occurring carbon-containing material that, when burned with air to produce heat or energy that can be converted into liquid fuels and other hydrocarbon (carbon bonded to hydrogen) products (Speight, James). There…

Challenges of fossil fuels 1. Not renewable energy Fossil fuels comprise of crude oil, coal and natural gas. It is not renewable and cannot be replaced. Plants and animals that existed millions of years ago became buried underneath the Earth’s surface. This formed as the fossil fuels. Since fossil fuels has limited supply, it can’t fulfil the world’s energy demand. Therefore, alternative energy source is needed to replace the fossil fuels. 2. Emission of carbon dioxide Combustion of fossil…

Fossils are essential to help explain the species of the past and how they lived and have evolved over time. The only thing that gives direct proof to what existed in the past are fossils as they are the physical remains, in rock form, of what existed. Today's technology for scientists is in fact so advanced that they can tell what certain species ate, how long they lived, and obviously what they looked like. This helps when talking about biological evolution because it gives scientists physical…

Firstly, let us take a look at fossil fuels and inventions that led to their heavy usage. Fossil fuels are combustible organic deposits, formed from decayed plants and animals that have been converted to crude oil, coal or natural gas by exposure to heat and pressure in the earth 's crust over hundreds of millions of years. Due to the development of steam engine in 1712, the popularity of coal as an energy source increased rapidly, and is one of the most used fossil fuel today for the production…

Whether it be the gasoline our cars utilize or the electrical currents that power our phone, everyone uses energy in some form. Most of the time, the energy being used are fossil fuels, e.g., crude oil, natural gas, and coal. Despite the wide audience that reap the benefits that fossil fuels provide, they actually do more harm to the Earth than most people think. 85% of America’s fuel usage comes from fossil fuels. The usage of fossil fuels do provide immense amounts of energy throughout…

America is currently at an energy crossroads. On one side, the country can lazily continue on its current path of disillusioned comfort with fossil fuels. However, oil, the fossil fuel we rely on most, has the shortest supply left and when it finally depletes it will take the country’s energy, economy, and environment. To avoid the catastrophic aftermath of the depletion of fossil fuels, the United States needs to change its path and abandon oil for a switch to clean renewable energy. The United…

Original Argument: Can Alternative Energy Really Replace Fossil Fuels? With our planet’s appearance changing rapidly, from the melting of the polar caps, to the loss of the Great Barrier Reef, we must recognize a cause for these issues. Many are quick to point fingers at fossil fuels, which are currently our main source of energy. These people demand a switch to alternative energy options, such as biofuels, solar, nuclear energy, and wind energy. Supporters of alternative energy believe that…

The problems associated with the use of fossil fuels as the worlds primary source of energy will have to be addressed sometime during my life time. Fossil fuels are not only very limited, the impact that this energy source is having on the environment will force the entire world to change our way of life. The primary byproduct of the use of oil is CO2, this release of CO2 into the atmosphere is causing what we know as global warming. As the levels of CO2 in our atmosphere increases heat that…
