Warm up: Grab a book, chrome book, and warm-up (student table by door) Quiz Wednesday Did you turn in Activity 6-7 Handout and the Power and work handout This past Friday?

Warm-up 2-21-18 Mr. Rinker uses 15N to move a wheelbarrow filled with dirt 30 meters, how much work does he do? Show work and units. 15N x 30m= 450 J  What is the power output if he moves the wheelbarrow in 40 seconds? 450 J/ 40 s =11.3 J/s= 11.3 watts How is solar energy stored in the biosphere? Photosynthesis of plants  What is acid rain? What is the pH of acid rain? When you burn coal the sulfur in the coal turns to acid : Chemically the burned sulfur forms sulfur trioxide which then reacts with the moisture in the atmosphere to form sulfuric acid What can we add to neutralize it? Can add base to fumes, typically calcium carbonate(CaCO3) Impact of CO2? The coal plant still emits CO2 which goes in to the atmosphere and contributes to greenhouse gasses. The greenhouse gasses keep heat from escaping from the earth, global warming.

Turbine Generator in Electric Plant Generator: is simply a device that moves a magnet near a wire to create a steady flow of electrons. The current is created due to a law of electromagnetism called Faraday’s Law of Induction, discovered in the 1800’s.  This law states that a wire conductor that creates movement through a magnetic field creates an electric current, and that the strength of the current is equal to the rate of change through the magnetic field.  So, the faster the copper coil rotates, the more electric current will be created.

2014: million barrels a day TX :3.3 ND: 1.1 CA: .6 AK: .5 1: What % of oil used every day in the US is produced in the US? 75% 2: Where are oil and natural gas found in the US?

1. Us Petroleum Production 1960 -> 2016 2. Us Petroleum Consumption 1960 -> 2016 3. Petroleum Imports 4. What year did we import than we produced 5. What % of consumption was met by US oil in 1954 6. And then in 1999

Crude Oil/Petroleum: Raw material is organic matter: remains of plants and animal After the breakdown of organic matter :High temperatures, pressure, and time due the rest It takes a very very very long long long time to become oil: 300 Million years “ maturation”, when organic matter turns to oil and gas .

Where is the oil. Oil underground stop@7. 28): https://youtu Source rocks: Mudstone and shale contain large pores and act like sponges but impermeable( Hard to penetrate) . Because they have sponge like characteristics they are able to store the oil These pores also store water, but. Because oil is less dense then water it’s able to slowly percolate toward the surface of the earth. As it moves upward most oil & gas will get stopped by another impermeable layer of rock which will form of seal. Reservoir: oil & gas trapped between the source rocks and the seal. What’s next: finding and drilling for oil

Seal Reservoir Source Rock: Mudstone and Shale

History Late 1800’s coal surpassed wood for home heating 1859 First successful oil-drilling in Pennsylvania @ 70 feet. 1920 Big oil discovered in Texas. (Everything’s big in Texas ) 1920’s US produced 2/3 of of the world’s oil. 1940’s After World War 2, oil took from coal as the dominant fuel, Truck fueled by gas instead of trains fueled by coal were now the main transport of goods and materials. 1950’s oil & gas surpass coal **** No source of energy has ever become so dominant so quickly***

Main areas of oil/gas resources is Texas, Alaska, California By 1998 only 12% of world supply <35% of our remaining oil left Geologists search for sedimentary basins to drill

Summary Oil & Gas (also coal) 300 millions year old organic material Found in reservoirs between Source Rocks and Seal. Late 1800’s coal replaced wood 1859 First oil discovered in Pennsylvania 1920’s US supplied 2/3 (66%) of the world’s oil 1998 US supplied 12% of the world’s oil Present: 35 % of oil reserves left
