| Question | Answer |
|---|---|
| 1.1 Define the concept of environment | the living and non-living elements of the Earth's surface and atmosphere. including human changes: cropland, buildings, planted forests |
| 1.1 Define the concept of natural and anthropogenic biomes | natural: Biomes which have not had sustained direct human interactions anthropogenic: Biomes that are the result of sustained direct human interactions within the ecosystems |
| 1.1 Define the concept of land cover change | changes that have taken place in natural environments due to a variety of natural and/or human induced causes |
| 1.1 Define the concept of ecosystem structure & dynamics | ecosystem structure: biotic and abiotic elements with a hierarchy of organisms. producers, consumers and detritus ecosystem dynamics: relationships between biotic and abiotic elements, which includes the flow of energy between elements |
| 1.1 Define the concept of biodiversity loss | the extinction of species worldwide, and also the local reduction or loss of species in a certain habitat |
| 1.1 Define the concept of climate change | long-term change in the statistical distribution of weather patterns over periods of time that range from decades to millions of years. |
| 1.2 describe the process of land cover change, including: deforestation | Deforestation: removal or clearing of forests generally for other uses. e.g. agricultural purposes |
| 1.3 Describe how remote sensing images are used to identify and measure the location, type, rate & extent of land cover change | the science of obtaining info about objects or areas from a distance location: range of scale. e.g. local, regional, global type: category of LCC. e.g. deforestation rate: speed at which changes have taken place extent: size & are of LCC |
| 1.4 Outline the impacts of world population growth on the type, rate and extent of land cover change | type: as population increases more demand for resources. impaction on 4 types of LCC rate: new ways developed to obtain resources faster extent of LCC: large amounts of land used to meet demands for resources |
| 1.4 Outline the impacts of growing affluence and advances in technology on the type, rate and extent of land cover change | type: new tech allows for new ways to contribute to the 4 types of LCC rate: new tech speeds process up. e.g. GMOs, tree cutters extent of LCC: increased as more and more land is used to obtain resoureces |
| 1.5 Outline how two factors account for differences in land cover change between two countries: Brazil & Australia land ownership | AUS: LCC are heavily regulated and punished when regulations are broken. e.g. deforestation and mining needs permits even on privately owned land Brazil: Government doesn't regulate LCC so clearing of forests or mining can cause great damage |
| 1.5 Outline how two factors account for differences in land cover change between two countries: Brazil & Australia government policy | AUS: strict policies and laws in place to prevent LCC even on privet properties Brazil: Polices favour economic growth over land protection |
| 1.6 explain the impact of aboriginal & Torres strait islander peoples land management practices on land cover change over time: mosaic burnings seasonal calendars | mosaic burnings: clears undergrowth, provides paths, prevents risks of forest fires, weed control Seasonal calendars: Noongar seasonal Calander, key to under standing flowering of plants, hibernations and when and where to hunt |
| 1.7 explain two impacts of land cover change: soil erosion & degradation urban heat islands | soil erosion and degradation: chemical and physical changes of the land that are enhanced by humans, reducing the quality of the soil. e.g. fertilisers Urban heat islands: warmer temps in urban areas due to man made environments (albedo) |
| 1.2 describe the process of land cover change, including: the expansion & intensification of agriculture | the expansion and intensification of agriculture: the increasing amount of land available for agriculture |
| 1.2 describe the process of land cover change, including: the growth of urban settlement | the growth of urban settlement: clearing and transforming of native vegetation to build infrastructure |
| 1.2 describe the process of land cover change, including: mining | mining: biotic and abiotic conditions, clearing of land, use and release of chemicals, dust and aerosols |
