What conditions in Alberta led to the formation of fossil fuels?
What conditions in Alberta led to the formation of fossil fuels?
Lacking oxygen, the buried plants only partially decayed, turning into a spongy mass of carbon-rich plant material called peat. This spongy mass was slow-cooked by the tremendous pressure and heat of geological forces, eventually hardening into coal beneath the Earth’s surface.
How were fossil fuels formed millions of years ago?
Years ago, when prehistoric animals and plants died, layers of rock and dirt gradually buried them. Over millions of years, heat and pressure from Earth’s crust decomposed these organisms into one of the three main kinds of fuel: oil (also called petroleum), natural gas, or coal.
What conditions need to be present millions of years ago to form coal?
Coal formed millions of years ago when the earth was covered with huge swampy forests where plants – giant ferns, reeds and mosses – grew. As the plants grew, some died and fell into the swamp waters. New plants grew up to take their places and when these died still more grew.
Where are fossil fuels found in Alberta?
About 80 per cent of Alberta’s crude oil production now comes from the oil sands. The province has three oil sands regions. The largest, and by far the most well known, is the Athabasca oil sands near Fort McMurray.
Do fossil fuels need oxygen to form?
‘ But we’ve known for a long time … that building up oxygen requires the formation of rocks like black shale.” Today, burning billions of tons of stored carbon in fossil fuels is removing large amounts of oxygen from the atmosphere, reversing the pattern that drove the rise in oxygen.
Where did the fossils of Alberta come from?
Throughout its geologic history, Alberta has been part of various shallow seaways next to this North American craton, and at times has been above sea-level, meaning that there is a mix of shallow marine and low-land terrestrial deposits.
How old is the history of fossil fuels?
Some forms of petroleum, coal, and natural gas were used thousands of years ago by various civilizations on various continents, according to historical records and archaeological finds. The history of the use of fossil fuels is as old as is the history of human civilization.
What was life like 100 million years ago in Alberta?
In the shallow seaway, fish and sharks swam alongside giant sea turtles and plesiosaurs, long-necked marine reptiles. While on land, it was a world of new colours as flowering plants arrived, and evolved new and beautiful ways to attract insect pollinators.
How are fossil fuels formed on the Earth?
Fossil fuels are a class of materials formed from dead organisms that sunk below the surface of the earth millions of years ago. All fossil fuels were organic material once, but different geological conditions such as pressure, temperature, rocks, and sediment, have led to the formation of different types of fossil fuels.
When does the formation of fossil fuels take place?
Fossil fuel formation refers to the process that takes place over the time span of hundreds of millions of years to produce a variety of fossil fuels including coal, oil, and natural gas.
