Fossil Fuels Presentation by Sung Kim What are fossil fuels? Fossil fuels are fuels that are formed by natural resources
such as anaerobic decomposition of buried
dead organisms. include an enormous proportion of carbon and hydrocarbons. What are the different types of fossil fuels?

There are many types of fossil fuels.
But there are three types of fossil fuels that are the most widely used, which is coal, oil, and natural gas. Coal - solid Oil - liquid Natural Gas - gas Coals How is coal formed?
Stages of coal formation
How is coal used as a fossil fuel? How is coal formed? Coal is formed from the trees and plants which grew millions of years ago. They delayed and sank into the ground, and were pressed under layers of rock and other minerals.
As this vegetation dried up, it turned into peat. Then it was heated and got an enormous amount of pressure over time. Later, it became coal. Stages of coal formation 1. Wood
Huge forests grew around 100 million years ago. 2. Peat
Vegetation dies and forms peat. 3. Legnite
As peat goes through continual amount of heat and pressure, it gets compressed to form legnite.
This goes on for a long period of time until coal if formed. 4. Anthracite
Anthracite is formed as time passes. How is coal used as a fossil fuel? - The 93 percent of the coal use in the U.S.A
is used for producing electricity

- In the past, coal was burned to fuel steam
locomotives. How is oil formed? Oil is formed from the remains of animals and plants that lived millions of years ago in water settings.

They were buried and under sediment and rocks

As time passes, heat and pressure turns the layers into crude oil. How is oil used as a fossil fuel?

It's burned in factories and creates a lot of gases that turn a turbine to make electricity.
It's used to fuel cars.
It's used to make crayon.
It's used to heat houses It's used in MANY ways How is natural gas formed? Formation of patroleum occur from hydrocarbon pyrolysis, in a variery of mostly endothermic reactions at high temperature and/or pressure

Natural gas is mostly made up of a gas called methane. Methane is a simple chemical compound that is made up of carbon and hydrogen atoms. How is natural gas used as a fossil fuel? Natural gases are burned to produce energy.
Natural gases can be used in many ways. Heating and cooking are the two most commonly known residential uses for natural gas.

The use of natural gas for heating, lighting and cooling purposes is typical in industrial settings. Natural gas performs numerous industrial functions, including incineration of waste, boiler fuel, drying and as a feedstock for a variety of products. Natural gas is used for the production of methanol Oil How is oil formed?
How is oil used as a fossil fuel? Natural Gases How is natural gases formed?
How is natural gas used as a fossil fuels? What are refineries and why are they important
to the production of fossil fuels? Refineries are industrial process plants that purifiy fuel substances like oil.

Refineries are important because refineries are where fuel substances are refined into more useful petroleum products such as gasoline, liquified petroleum gas, heating oil, diesel fuel, etc... Discuss the Exxon Valdez spill incident, the
clean up and the effects it had on the environment On March 24, 1986, the tanker Exxon Valdez, route from Valdes, Alaska to LA, California, ran agound on Bligh Reef in Prince William Sound Alaska. The vessel was traveling outside normal shipping lanes in an attempt to avoid ice. Within six hours of the grounding, the Exxon Valdez spilled approximately 10.9 million gallons of its 53 million gallon cargo of Prudhoe Bay crude oil.

Eight of the eleven tanks on board were damaged. The oil would eventually impact over 1,100 miles of non-continuous coastline in Alaska, making the Exxon Valdez the largest oil spill to date in U.S waters.

2,000 sea otters, 302 harbor seals and about 250,000 seabirds died in the days immediately following the spill.

The oil spill clean-up has cost the company $2.5 billion. Clean-up took place from May of 1991 through July of 1991 and clean-up of the incident was done by using dispersant, a surfactant and solvent mixture. Describe the Deep Water Horizon oil catastrophe discussing the indicent, the clean-up attempts, and the effect it is having on the environment of the Gulf of Mexico and surrounding areas. Two days before the oil spill, there was a huge explosion which killed eleven workors and injured seventeen others.

The explosion caused the Deepwater Horison oil spill by damaging an oil well. The oil spill originated from a deepwater oil well 5,000 feet below the ocean surface.

The estimates have been made for the amount of oil discharging, ranging from 210,000 gallons to 4,200,000 gallons of crude per day. Impacts of the Deepwater Horizon oil spill More than 400 species that live in the Gulf islands and marshlands are at risk, including the endangered Kemp's Ridley turtle, the Green Turtle, the Loggerhead Turtle, the Hawksbill Turtle, and the Leatherback Turtle. In the national refuges most at risk, about 34,000 birds have been counted, including gulls, pelicans, roseate spoonbills, egrets, terns, and blue herons. A comprehensive 2009 inventory of offshore Gulf species counted 15,700. The area of the oil spill includes 8,332 species, including more than 1,200 fish, 200 birds, 1,400 molluscs, 1,500 crustaceans, 4 sea turtles, and 29 marine mammals. Deepwater Horizon oil spill is 20 times larger than the Exxon Valdez oil spill. It polluted water and killed many species, just like Exxon Valdez oil spill did Clean-up attempts People tried to stop the oil from spilling by capping the well, but it has been unsuccessful so far. But efforts are ongoing.

In order to protect the coastline beaches and wetlands, floating booms are used to physically prevent the oil floating on the sea from reaching them.

Also, people used dispersant to clean-up the oil spill, which was used in Exxon Valdez oil spill
