Unit 3: Regional Resources Power point presentation on the classification of resources

What is a resource?  Means available; stock or supply that can be drawn on; asset - Pocket Oxford Dictionary  Anything obtained from the living and non living environment to meet human needs and wants. It can also be applied to other species - Miller, G. T.

Classifying Resources Renewable Non- Renewable Natural Human Sustainable Non Sustainable Finite Infinite Recyclable

Classifying Resources- Activity  To help students think through the main resource classification.

Renewable Resources  Materials which can be used and then replenished either natural or with human assistance within a relatively short space of time, for example; food crops, water, forests, animals and fish

Non Renewable Resources  These exist in finite amounts and cannot be replaced by natural processes or are replaced at a rate slower than the rate of use, for example; coal, gas, oil and diamonds.

Natural Resources  These occur as a natural part of the environment, and include; air, water, plants, soil, fish, birds and unique landforms

Human Resources  Goods and services provided as a result of human activities. These include manufactured goods, money, education, buildings and information

Recyclable Resources  Once a resource has been used, it may be able to be used in a different format. Examples of recycled resources include: paper, aluminium, steel and some plastics

Sustainable Resources  The rate of use of a resource is such that he amounts taken will not effect the resource’s ability to renew itself, and the same rate of productivity can be maintained into the future. For example, quota’s of fish or trees harvested in a season

Non Sustainable Resources  The rate of use of the resource outstrips

Finite Resources  Once the resources has been used u, it cannot be replaced. In other words only a fixed amount of the resource is available. Oil and coal are examples of fine resources.

Infinite Resources  A resource that is unlimited as it is capable of being replenished. Solar energy, wind energy and human interventions are examples of infinite resources  ….. Please note that many other students find this one difficult to understand as on one of the previous examinations, when classifying the internet, as the size of the resource can become infinite, but the resource itself is not infinite  A resource that is unlimited as it is capable of being replenished.

Classifying WATER as a Resource!!  So…….How do we understand WATER as a resource to understand the complexities of the Murray Darling Basin System??

What do we use water for?  Brainstorm activity on the board (could give students heading to help)  How do these uses change depending on various factors? E.G. the economic or environmental conditions of a country  Brainstorm activity on the board (could give students heading to help)  How do these uses change depending on various factors? E.G. the economic or environmental conditions of a country

Various Water Uses Domestic e.g. cooking, showering Environmental Health of eco- systems Strategic Nations security- access to clean water Recreational Boats, water skiing Aesthetic In gardens, fountains Spiritual Religious ceremonies Economic Crops, animals, production, transport, power Political Keeping powers in control and influence Other?

The Water Cycle  See handout

Classification of Water as a resource Renewable Passing through different stages of the water cycle Recyclable Once used, it may be able to be used again in a different format e.g. gray water Finite There is a limited amount in the hydrosphere, atmosphere, lithosphere and biosphere
