Geography Exam 112
| Question | Answer |
|---|---|
| Minerals | naturally occurring, pure, non-living substances that are found in the rocks in the earth. When refined yield a group of materials that are metallic minerals (copper, gold, iron etc.) |
| Fossil Fuels | are any mineral that can be burned to produce energy (coal, oil, natural gas etc) |
| Industrial | minerals (salt, asbestos) are used by industry manufacturing |
| Mineral reserves | Mineral deposits that are economical to mine |
| Geology | is the science that deals with the dynamics and physical history of the earth, the rocks which it is comprised of and the processes which alter the earth |
| Geologists | are experts that study the history, composition, and structure of the Earth’s crust |
| Ore | mineral is rock that provides enough valuable minerals to make mining profitable |
| Underground mining | is the technique used to recover deep mineral deposits |
| Strip mining | is the method of mining used to recover mineral deposits located very near the surface |
| Open Pit Mining | a method of mining that utilizes a large hole that is dug for the purpose |
| Groundfish | fish, such as cod and sole that live and feed near the bottom of the sea |
| Pelegic Fish | fish that feed and are caught near e. salmon, tuna, herring |
| Shellfish | molluscs and crustaceans such as oysters, shrimps and lobsters |
| Balance of trade | difference between value of exports and value of imports. If exports exceed imports, there is a trade surplus. If imports exceed exports, there is a trade deficit. |
| Continental Shelf | gently sloping outer edge of a continent, that exceeds below surface of the ocean to a maximum depth of about 200 meters |
| Fishing Banks | shallow area on the continental shelf that provides a feeding and spawning ground for fish |
| Plankton | microscope plants and animals eaten by small fish and shellfish |
| Inshore Fishing | commercial fishing that takes places within a few kilometres of shoreline. Small fishing boats go out to sea and return to shore each day |
| Offshore Fishing | ocean fishery done from boats longer than 25 meters. The boats stay at sea several days before returning to share with their catch. |
| Sustained Yield Management | use of a renewable resource at a rate that allows the resource to renew itself. For example, the number of fish caught should not be greater than the number fish reaching maturity |
| Aquaculture | protection of fish on other marine products or fish forms |
| Overfishing | The catch allowed by the federal government each year appears to have been too high |
| Improved Fishing Technology | By the later 1960s, the foreign fishing fleets of countries such as Russia and Japan caught far more fish than sustained yield methods would have allowed |
| Destructive Fishing Practices | When trawlers were trying to catch one kind of fish; many other types of fish may have been caught in the nets. These unwanted fish, which were already dead, were usually thrown away |
| Changes in Natural Conditions | environmental changes becoming the blame. Water temperatures become cooler (changes migration routes), decline un sealing industry caused increase in seal population seals are eating most our fishes |
| Commercial Forest | part of a forest that has large enough trees and is closer enough to a market to allow it to be harvested by the forest industry |
| Non-commercial Forest | part of a forest that has trees too small or is too far away from the market |
| Boreal Forest(and Taiga forest) | coniferous (needle leaved) forest that stretches from east to west across Canada, south of the tundra but north of the grasslands |
| Mixed Forest | vegetation region that combines both coniferous and deciduous trees. If is a transition zone between the deciduous forest and boreal forest |
| Clear cutting | logging method where all trees in an area (except for very small ones) are cut at one time |
| Shelterwood Logging | method of forest harvesting in which up to 70% of trees are cut, leaving small patches of old growth standing to provide seeds for regeneration |
| Selective Cutting | lumbering technique in which only trees of certain type, size, quality are cut |
| Acid Precipitation | rain, snow, or fog created after sulphur dioxide and nitric oxides mix with water vapour in the atmosphere. Acid precipitation kills vegetation and turns lakes acidic, causing fish to die and wildlife to disappear |
| Silviiculture | branch of forestry dealing with the cultivation and care of forests |
| Primary Industries | industries that deals a production of primary products such as minerals that are mined or quarried, or an agricultural product that is harvested in its raw state eg. mine- raw material |
| Secondary Industries | industries dealing with manufacturing or construction eg. factory |
| Tertiary industries | industry that provides services rather than goods eg. ski resort, services |
| Quaternary Industries | services that provide information |
| Drainage Basins | drained by a river and its tributaries. One drainage basin is separated from another by an area of higher land called a watershed. |
| Watershed | an area of high land that separates one drainage basin from another |
| Withdrawal Use | actually removes the water from the human body. Uses thermal power generation and manufacturing, municipal, agricultural, and mining activities |
| Location | where a place is. Every point on earth has a specific or absolute location that can be precisely determined by using latitude and longitude |
| Relative location | deals with the interaction that occurs between and among places |
| Place | refers to the personality or special characteristics of a particular site |
| Society and Environment | Geographers study human/environmental interactions to look at all the effects- positive or negative- of human occupation on the land, atmosphere, and biosphere |
| Movement | resources, products, other life forms, information and ideas move from location to location |
| Regions | a basic unit of geographic study is the region- an area on the earth’s surface that is defined by certain unifying characteristics |
| Physical Pollution | Is the least harmful because it deals with floating garbage, old tires, paper litter, pop cans, and bottles are not pleasant to look at, but are easily spotted so clean up is easy |
| Biological Pollution | Deals with bacteria and viruses that enter lakes and rivers from a variety of source. A lot from sewage of cities and towns, about 20% of Canadian cities put their raw sewage into lakes and rivers |
| Chemical Pollution | Metals and solvents from industrial work can pollute rivers and lakes. Pesticides are used in farming to control weeds, insects and fungi. Petroleum is another form of chemical pollutant that usually contaminates water through oil spills (ship ruptures) |
| Caldera | is a cauldron-like volcanic feature usually formed by a collapse of land following a volcanic eruption |
