Fossil fuels are the remains of ancient plants and animals that have undergone heat and pressure over millions of years to form coal, oil, and natural gas. Coal forms from decaying plant matter that is compressed over time. It is primarily used to generate electricity but can also be burned for heat. Oil forms from the remains of marine organisms and is refined for use in transportation and manufacturing. Natural gas forms in a similar way from organic material and is a cleaner burning fuel used for electricity and transportation. Refineries process crude oil into usable fuels and products. Major oil spills like Exxon Valdez and Deepwater Horizon have caused environmental damage that persists for years.

“Fossil fuels are the fuels formed by natural processes such as decomposition of dead and buried organisms. “ Fossil fuels are buried flammable geologic deposits of organic substances such as dead plants, and animals that got deposited under several thousand feet of silt.
These deposits decayed with the passage of time and got converted to natural gas, coal, and petroleum due to the extreme heat and pressure inside the earth’s crust. They are also known as non-renewable sources of energy as it takes a very long time for it to replenish. Types, Formation and Uses of Fossil Fuels
Fossil fuels are of the following types:
Coal
Petroleum
Natural gas
A beginner level presentation which introduces coal and petroleum , their production and what their excess usage leads to. The image quality and some features may be reduced to improve compatibility.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. What are fossil fuels? Fossil fuels are the carbon rich remains of ancient vegetation and other organisms that have endured intense heat and pressure inside the earth over periods of millions of years.
3. What are the different types of fossil fuels? The different types of fossil fuels are coal, oil and natural gas.
4. How is coal formed? Coal forms from the remains of plants which died in prehistoric swamps and wetlands. Organic plant matter at various stages of decay form peat, which, under certain pressure, time and heat conditions experiences slow rates of bacterial decay and eventually goes on to form coal. The process through which coal forms from such ancient plants is known as coalification.
5.
6. Bituminous: Has a higher carbon content with a higher heating value than lignite. Contains less water and is therefore harder than lignite
7.
8. How is oil formed? Oil was formed from the remains of animals and plants (diatoms) that lived millions of years ago in a marine (water) environment before the dinosaurs. Over millions of years, the remains of these animals and plants were covered by layers of sand and silt. Heat and pressure from these layers helped the remains turn into what we today call crude oil.
9. How is oil used as a fossil fuel? Oil is carried in pipelines and large tanker ships. A refinery changes the oil into products like gasoline, jet fuel and diesel fuel. It's also burned in factories and power plants to make electricity. The oil is burned, which produces gases that turn a turbine to create electricity.
10. How is natural gas formed? Millions of years ago, the remains of plants and animals (diatoms) decayed and built up in thick layers. Over time, the sand and silt changed to rock, covered the organic material, and trapped it beneath the rock. Pressure and heat changed some of this organic material into coal, some into oil (petroleum), and some into natural gas — tiny bubbles of odorless gas.
11. How is natural gas used as a fossil fuel? Natural gas is the cleanest burning of the fossil fuels. Natural gas can be used as a substitute for gasoline or diesel fuel in internal combustion engines.
12. What are refineries and why are they important to the production of fossil fuel? A refinery is a production facility composed of a group of chemical engineering unit processes and unit operations refining certain materials or converting raw material into products of value. It is important to the production of fossil fuel because it converts raw material into a lot of fuel that we need.
13. The Exxon Valdez oil spill incident On March 24, 1989, the tanker Exxon Valdez grounded on Bligh Reef in Alaska's Prince William Sound, spilling nearly 11 million gallons of Prudhoe Bay crude oil into a remote, scenic, and biologically productive body of water. It was the largest single oil spill in U.S. coastal waters. Many parts of the Alaskan marine environment have begun to show signs of significant physical and biological change: waters have warmed, ice has receded, and populations of fish and mammals have declined. In order to clean this mess up, they tried to displace it with high-pressure hot water. However it displaced and destroyed the microbial populations on the shoreline, so they stopped. There are oil remain in the sandy soil of the contaminated shoreline, declining at a rate of less than 4% per year.
14. The Deep Water Horizon oil catastrophe incident The spill started with an oil well blowout on April 20, 2010 which caused a catastrophic explosion on the Deepwater Horizon offshore oil drilling platform. On May 1 two aircraft were employed to spray oil dispersant. The effects are being felt in towns and cities across the area -- this is in addition the local wildlife in both the land and sea that are dying by the thousands.
