To. Honourable Miclelle Mungall
Hello, Ms. Mungall. My name is Trina Kim from riverside secondary school grade 12. I’m international student who came from Korea 2 years ago. First of all, I would like to say thanks to you, because of your great managing with British Colombia’s energy people can live comfortably and safely. However, I want to carefully suggest about the fracking (Hydraulic Fracturing). I learned what fracking is and what might effect to human in my geography class. At beginning I thought that is a reasonable way to get a natural energy and it will safe from pollution. While my teacher showed me a documentary I shocked about that. The documentary includes the examples about doubt from pollution of fracking. Many people were struggle with polluted water. They asked about that diary water but it seems like all companies or government avoid the fact and responsibilities. Imagine shooting a water gun on a sand castle. If you use strong water pressure, sand casting will fall down. Even assuming that the water is supporting the ground to some extent, the weakened ground will increase the likelihood of sinkholes. The positive side of Fracking, it has revolutionized the US energy industry. The process is expected to reduce market dependence on relatively variable foreign imports and contribute to reducing fuel costs in the United States by up to 40 percent. However, Even if the pipes that extract the shale gas from the extraction process and the parts that block the groundwater are well sealed, the inevitable cracks in the rocks cause the methane to flow into the groundwater while penetrating the pipe down to several thousand meters. This pollution causes more damage to people’s health and to save a few dollars. Me who love Canada as much as Korea, I really hope this will not happen in Canada.

- Weathering: first step of denudation. disintegration or disintegration of rocks near the earth’s surface.
Erosion: removal and movement of rock. associated organic matter.
Transportation: carried out by water, ice, wind or wave action. Integral part of erosion.
- Water goes into fractures and freeze into ice. In this process, the volume of water expands so the gap getting wider. All chemical weathering need water.
- Positive: could get a new landmark, helps geographical study, recourses,
Negative: rockslide, crack of building became dangerous
- Because of the air pollution, the acid rain might contribute to (limestone)weathering physically, step the rock and break it (physical),
- More surface area means more area could reflect by chemical, so it increase the weathering
- Some types of rocks weather more rapidly in humid climates, while dry climates make other rocks more susceptible to attack. Limestone weathers rapidly in areas with wet climates, where rainwater mixed with carbon dioxide in soil or creates a weak acid that dissolves the limestone to form crevices and valleys.
- Salt crystals grow; they expand and exert high pressures on the surrounding materials. Soon, it breaks off and falls away.
- Tropical(hot and humidity) area could chemical weathering.
1.Explain why the plastic nature of the asthenosphere and convection currents are important to the theory of plate tectonics.
- The asthenosphere makes the plastic can flow slowly.
2. Which type of plate boundary is:
- Found at mid-ocean ridges? à Diverging
- Most often associated with forming mountain belts on continents? à Collision
- Associated with the San Andreas fault? à transform fault
3. Is it better to live near a regularly active fault line or an inactive fault line? Explain.
- Active fault will be better to live. Inactive fault means land is not circulating. If the land is not circulating and the earthquake is happen, the victim will be worse than active fault.
4.Explain why volcanic activity along transform faults is relatively rare.
5. Use a plate boundary map to explain why Japan and Indonesia should face more earthquakes than anywhere else in the world. (provide the map you used in your post)
- Both of them are placed on the plate boundary.
6. Use a plate boundary map and explain how plate tectonics would affect where you live.
- Korea was near to plate boundary. However, Japan became a barrier of earthquakes or tsunami. So the rate of the victim could be lower than Japan.
7.Use a plate boundary map and explain the relationship between the position of volcanoes, fault lines and plate movement.
- Usually volcano is created near the plate boundary. Also each plates are have different direction to move. It represent that the reason why earthquakes are occur often. Also the plate’s movement, earthquakes, and volcano, the fault lines might be have different order or shape.
- Using a plate boundary map and the population density map below, which countries are at risk of having many people affected by earthquakes and volcanic activity?
- Japan will get the most hardest effect by earthquakes. As the population density map show, east Asia has high population. One of the high country is Japan. But as the plate boundary map, Japan is placed on the plate boundary not the beside. Also, the volcano is located a lot in Japan. Also, other countries are mostly connected with continent. Hoevere, Japan is completely island. So they might get tsunami.
For these reasons Japan is consider to the most affected country by plate.
1.How do the formation of rocks affect your life? Organize your response by rock type.
- Igneous : in Korea we have a statue names ‘Dolharbang which is a symbol representing an island. It’s made by a Igneous because of that I could understand that volcanic island’s past.
- Metamorphic: I could find and use marble statue or table, walls.in my life.
- Sedimentary: I ought some Jewelry. I talked about Birthstone with my friend
2. In what ways is the rock cycle affected by the energy within the earth, the atmosphere and the hydrosphere? Explain which rock types would be affected by each.
- hydrosphere-> sedimentary rock
- Atmosphere-> erosion
3.Explain why sedimentary rocks usually do not contain metallic minerals.
- Metallic deposits are most commonly derived from hydrothermal activity and/or magmatic actions which in general are a concentrating process. But the sedimentary rocks is made up of a process in which several particles are deposited and hardened.
4. Look ahead to the map on page 87, explain where in Canada you would expect to find metamorphic rocks forming.
5. If you were attempting to discover oil and gas deposits in Canada, what conditions would you be looking for?
- sedimentary rocks, dried up rivers
6. Explain how it is possible to distinguish between sedimentary and metamorphic rocks that appear layered.
- If the layers are arranged in parallel to the direction perpendicular to the pressure or if they are patterned like marble, they are metamorphic rocks
- If the layers are parallel to sea level, or if there are fossils that are left with remains or traces of living organisms, they are sedimentary rocks.
7. Use the rock type map of Canada to identify the major rock types for each province/territory and the possible resources that may add to their economy.
- sedimentary rocks. because Canada has many coast
8. Explain how rocks affect politics and economics around the world. give specific examples.
- Trade the rocks for Interior industry, Building industry, or Tourism industry.
- Gold rush
