Chapter 8 Fuel & Mineral Resources
Transcript of Chapter 8 Fuel & Mineral Resources
Mining makes good money, From Diamonds to Gold. Mining is VERY dirty and Hard and a little fun fact is that Diamonds are worth more than $1000!! But some Rocks and Ore's they find are BLASTED and dragged from the Earth, then crushed and refined. After crushed they become Minerals. Mineral concentrations usually range from less then 1 percent upward to 30 percent , leaving great quantities of waste material called mine tailings. Today, much of it is used to fill in areas that have already been mined. Dangerous compounds found in the rock can easily pollute lakes, oceans, and groundwater supplies. Gases from the refinery smokestacks can cause acid rain and smog. Canadian mines have made improvements in cutting air and water pollution , and continue working to reduce the environmental impact of mining . Part 2 Mineral

Planet Several steps takes you exploring and then mining. The First things Geologists do is use maps and field surveys to locate the best possible locations for mineral deposits. In some situations samples will be collected from the mines surface for research. Other times they will use a low-flying aircraft with instruments and other pieces of machinery attached to it to take samples from below the mines surface. Then they drill to the core to identify the amount of quality and how much can be distributed from these minerals. These mining operations are only started if there is a valuable deposit of money brought in from the minerals, otherwise it would just waste money for the mining company. Their are two major kinds of mining operations: an open-pit and underground. Open-pit mines are more safe then underground mines but take longer to dig. Underground mines on the other hand are less safe because the mine could collapse on you but you will find most likely finer and better minerals and amounts of them in an underground mine. Part 1 Fuel
Resources Erica's planet Hannah's Planet Definition of Mine Tailings: Waste materials,
Produced from Mining Sometimes, mineral deposits are thousands of metres below the surface. Usually, a vertical shaft is drilled straight down through the rock, so an elevator (called "the cage") can carry miners up and down. Horizontal tunnels (called stopes) fan out from the mine shaft at different depths. They cut through veins of miners found in the rock. sustainability. fossil fuels Sustainability: Use and conservation of resources in a way that does not deplete them. Fossil Fuels: Fuels developed by the decay of plant and animal life over millions of years. Word Definition Non-Renewable: A non-renewable resource is a natural resource which cannot be produced, grown, generated, or used on a scale which can sustain its consumption rate. These resources often exist in a fixed amount, or are consumed much faster than nature can create them. Canada has 2 types of non renewable resources: fuel and non-fuel minerals. They are formed in different ways and found in different places. Some non-renewable fuel minerals include oil, natural gas, coal, and uranium (The source of Canada's natural waste problem) . These fuel minerals can not be replenished once it is used up, such as fossil fuels. We need to make them last longer, to do this we can use the 3Rs; reduce, reuse, recycle. This is 3 important ways to protect all types of resources. Geographers call this sustainability, conserving natural resources for the future.
Petroleum, natural gas, or coal are 3 resources called fossil fuels because they contain the remains of dead plants and microscopic animal life. Combustion of a fossil fuels can burn and create heat, light, electricity, or energy to power engines. By : Hannah and Erica By : Liam k and Brandon By: Erica! :) Thank you for watching our presentation on Fuel and Mineral Resources!!!! 2 videos on Non-Renewable resources 3Rs are important! (Reduce, Reuse, Recycle) Brandon's Moon Some examples of Mineral resources are:
-Gemstones, to make jewelery, art, ornaments and other items.
-Sand is found on beaches
-Gravel is usually found in river beds, dry river and streams and other places.
-Salt is found in salt mines in the ocean Definition of Mineral resources:
Natural resources in the form of
Minerals. This video is magnificent as it shows how
from mining years before was just pickaxes and tnt
to now it is machinery witch makes it more safe. j The biggest underground mines with the most quantity are all located in South Africa. Each Year thousands of miners lose their lives mostly
from mining coal and hard rock minerals. Most of these deaths occur in third world countries due to the lack of new and safer conditions. Geologists - A geologist is someone who studies a place and finds out what kind of minerals it has in it and how much of these minerals
Mineral Deposits - A mineral deposit is something that is taken from the ground or anything that is storing minerals and is then examined to find out what kind of nutrients and minerals are in these pieces of earth.
Open-Pit Mining - Open-Pit mining is the safer method for mining because the explosion pattern doesn't make the mine collapse but makes a stair like pattern though it may take longer to mine. Also, the layers that are mined are thinner and easier to mine because they are the softer layers of the earth.
Underground Mining - Underground mining is where miners find more valuable but sometimes are not the largest quantities of minerals. Most underground mines are mostly gold, diamond, and magnesium and other valuable minerals like silver. There also have been many horrible and terrifying accidents in underground mining where many people have lost their lives. Did you know that Canada is one of the countries
that is leading in mineral production?! The worlds attention was just grabbed when they found out of how wealthy our country was during the major gold rushes at Barkerville, British Columbia, in 1856 and Dawson City, Yukon, in 1898. When the early 1900s had come around, prospectors and geologists were swarming our land and looking for more of this hidden treasure. The places where most of these people were going, were to places that had molten magma which had slithered up from the center of the earth through cracks in the earth. These magma flows that had come up from the earth were called "igneous intrusives" hence how it had intruded the rock that had been their before. These magma flows were responsible to holding large quantities of different kinds of metallic minerals such as, gold, silver, iron ore, and sometimes nickel. Nowadays Canada is one of the wealthiest countries in the world and this is one of the reasons why. Fossil Fuels and the Environment
We rely on fossil fuels a lot in our everyday lives,but when they are burned they are released in the air, it creates nuclear waste,carbon monoxide,volatlile organic compounds, and sulphur oxide emissions. This is causing Canada to have an extreme environmental problems. How are Fossil Fuels Created?
Fossil fuel was formed over hundreds of millions of years ago by decomposing plants. This is how it happens, layers and layers of rock, mud, and sand covered the dead plants thousands of feet under the earth, which fossilized them, This is also how oil and and natural gas is formed. Then they are buried under the oceans and rivers. After a long period of time the water receded back and the pressure and bacteria create the oil and natural gas, the oil and gas start to rise up from underground but then it is stopped because of somethng called the caprock. The caprock holds the gasses so they don't spill onto the surface and when the oil companies drill down in the earth they look to find the caprock because that is where it is all kept in the earth, and that's how fossil fuels are created. videos! By: Hannah!!!! Important words Fossil Fuels:
- Fuels developed by the decay of plant and animal life is over millions of years. Caprock:
- a layer of rock that overlies a salt dome and consists of limestone, gypsum, etc.
