Plate Tectonics

  1. The asthenosphere and convection currents are important because the movement caused by the asthenosphere set in motion by convection currents is what we use to determine the places of different plates and how they change and deform the earth’s lithosphere.
  2.  Diverging plates make mid-ocean ridge// Converging plates make mountain belts on continents //Transforming plates are associated with the San Andreas fault
  3.  It is better to live near a regularly active fault line. It is regularly giving out the pressure caused by the movement of plates rather than an inactive one which has its pressure built up until it gives out a massive amount of pressure all at once which is far more dangerous.
  4.   Since the plates are sliding, it creates fault lines and earthquakes more than volcanoes. There is little uplift on either side, so there isn’t enough magma formation to lead to volcanoes.

Japan and Indonesia are very close to the edges where the tectonic plates  (Pacific plate with Eurasian plate) (Indo-Australian plate with Eurasian plate) collide. It is also on The Ring of Fire which is the area around the Pacific Ocean that has 3/4 of the world’s most active and dormant volcanoes.

6. BC is along the Ring of Fire which means that there is bound to have an earthquake sooner or later. The Juan de Fuca plate is being subducted under the North American plate which is creating pressure that hasn’t been released in a long time. This means that the residents of BC could experience a devastating earthquake soon. Vancouver especially is near the juncture.

7. Volcanoes are usually found along converging plate boundaries where one plate is being subducted under the other, and diverging plate boundaries where plates are moving apart from each other. They are rarely found along fault lines. Fault lines are where plates are sliding past one another (transforming).

8. Countries that are at risk of earthquakes and volcanic activity are Japan, Italy, Indonesia, Philippines and countries in the Caribbean Sea. These countries are the most population dense ones also situated on the edges of tectonic plates.

Rock and its Role

  1. SEDIMENTARY ROCK- The oil that I use to fuel my car is found thanks to the help of sedimentary rock METAMORPHIC- The desks that I use to study on are grounded by the metal poles IGNEOUS ROCK- The counters and tables at home have a surface of polished granite (intrusive) on the surface which makes cleaning after eating or spilling things a lot easier. It also looks really nice.
  2.  Rock cycle> Rocks are heated by the heat from below, making them decay at the surface and sink down. When metaphoric rocks melt, it becomes magma (a source of heat) and magma cools to make igneous rocks. Hydrosphere> Creates sedimentary rocks by the flow of water from oceans or rivers pushing them // Atmosphere> Causes erosion from the wind that removes rocks from one location to another
  3. Metals are denser and may sink and settle before it gets to oceans and lakes, and water washes minerals (lighter materials) further away which separate them.
  4.  We would expect to find metamorphic rocks along the west coast, BC because of the converging plates.
  5.  We would look for sedimentary rock, dried up rivers and lakes, ground water and flat land
  6.  Metamorphic rocks have a vein of minerals, they are denser, and harder than sedimentary rocks which have no vein of minerals, are less dense, and are softer
  7.  ALBERTA- Sedimentary rocks in Alberta, BC- North of BC, SASKATCHEWAN- south of Saskatchewan there is a large chance there are oil deposits which is a useful and valuable resource all around the world, it also has a relatively large population and most of the population require oil for fuel. QUEBEC- A great deal of Intrusive rocks are found north of Quebec which can be used to create aesthetic furniture which is valuable for homes like granite.  MANITOBA- Volcanic rocks can be used to make very beautiful charms for jewellery which can sell at high prices to strengthen economy. ONTARIO- metamorphic rocks which can be used to make tiles and sell to strengthen economy. YUKON- North of Yukon and  NORTHWEST TERRITORIES- the west, north and south side of NorthWest Territories have lots of sedimentary rocks like coals can be used for mining which can be sold at valuable prices which can strengthen their economies.  NUNAVUT- intrusive igneous rocks like granite can be used to sell because it is very strong and can stand up against the harsh weather conditions in the north of Nunavut.  PEI- have sedimentary rocks like coal which can also be used as electrical power and a source of heat which is a valuable resource in the economy.  NEW BRUNSWICK- Sedimentary rocks like sandstone can be used for construction which will be valuable because if is stronger than wood and New Brunswick experiences harsher weather conditions than the west side.  NOVA SCOTIA-Lots of intrusive rocks like gabbro which can be used to make sculptures which are very valuable as works of art. NEWFOUNDLAND- Have lots of metamorphic rocks such as slate up north which can be used to make roofs which can be used to help build houses for the general population.
  8.  Oil pipelines (Alberta to BC), more cement roads for increased population (BC may want to broaden roads for the increased immigration), rocky mountains making boundaries (BC and Alberta), Gold Rush (increased value of BC/ basically made BC)

Safety Cheat Sheet

Fire- Do not try to put out a grease fire with water. Water will not put out a grease fire but rather make it more combustable and dangerous.

Burns- Make sure the lid of the pot can let out steam. To prevent a steam burn from the accumulated heat, it is important that there is a way to let out the heat by tilting or sliding the lid.

Chemicals- Be knowledgeable of WHIMIS. This lessens the chances of chemical poisoning or potential death happening in the kitchen.

Slips/trips/falls- Clean all spills immediately. This is important because it will prevent any falls that could occur which are dangerous.

Cuts- Apply direct pressure to the wound. This will stop heavy bleeding coming from the wound.

Heavy lifting- Use knees and not arms. There is more strength for efficient lifting if you use your knees predominately.

How to prevent food poisoning- Separate raw and cooked foods. Separating raw and cooked foods will lessen the chances of cross contamination and food poisoning.

Waste management- Do not let waste accumulate in cooking/ work area. Not getting rid of waste immediately after being done with it will cause the waste to accumulate and possibly contaminate or damage food.

Personal hygiene- Pull and tie long hair back with a rubber band. Any hair longer than shoulder length is at a greater risk of unsanitary practices and food contamination.
