Mining Fossil Fuels

What Fossil Fuels are mined?

1. Coal  
2.   Oil
3.   Natural

How are they mined?

1. Coal can be extracted from the earth either by surface mining or undergroundmining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
2. In conventional natural gas deposits, the natural gas generally flows easily up through wells to the surface. In the United States and in a few other countries, natural gas is produced from shale and other types of sedimentary rock formations by forcing water, chemicals, and sand down a well under high pressure
3. Other instruments such as gravimeters and magnetometers are also used in the search for petroleum. Extracting crude oil normally starts with drilling wells into an underground reservoir. When an oil well has been tapped, a geologist (known on the rig as the "mudlogger") will note its presence

Where are they mined?

1. Oil - Today, petroleum is found in vast underground reservoirs where ancient seas were located. Petroleum reservoirs can be found beneath land or the ocean floor. Their crude oil isextracted with giant drilling machines.
2. Coal - New Zealand coal reserves are in excess of 15 billion tonnes, mainly in Waikato, Taranaki, West Coast, Otago and Southland. Over 80% of the reserves are in Southland lignite deposits worth $100 billion. Coal is produced from four underground and 21 opencast mines.
3. Gas - Oil and gas are produced from 21 petroleum licenses / permits, all in the Taranaki basin. The most important fields are Kapuni, Maui, Pohokura and Kupe. Exploration for oil and gas reserves includes the Great South Basin and offshore areas near Canterbury and Gisborne.

Activity: Cookie Mining

On the sheet provided you need to make two drawings of your cookie. 

1. Looking down at your cookie.

2. From Side on -  of the imaginary habitat that will live on the top of the cookie. ( trees, buses, flax, sea, etc)

Material:

1.  toot pick
2.   paper plate
3.  cookie 
4. paper

Steps:

1.   first you need to draw the cookie and after you finish the drawing miss will give you a stick
2.   after that you need to mined the chocolate on the cookie without breaking the cookie  
3.   you need a toot pick to mined it so you have to get a toot pick and use it 
4. while your mining you need to mined it at the top of the paper plate so you don't need to pick the small pieces up. 
5.   after you mined it you need to show it to a teacher and if she said it's ok you can it.

Findings: What did you find out as a result of your mining?
i actually didn't finished it cause we have esol but i still had finished the cookie mining but not the bog thats what i know for now

Conclusion: 
cookie mining is fun you can actually think you really we're mining cause you mined the chocolate carefully so yeah and i learned a lot on it.
