Renewable energy
Energy that can be obtained from natural resources that can be constantly replenished
Sustainable Development
Development that meets the needs of the present, without compromising the ability of future generations to meet their needs
Why should/do outdoor adventurers have detailed understandings of the environments they visit?
In order to properly plan and prepare for activities. They are more likely to have safer and more sustainable interactions. Not understanding the environment could lead to increased risk.
Biotic, Abiotic – What is the difference?
Abiotic refers to a living organism, abiotic refers to a non living feature in an environment. Animals and birds compete for food and habitat. Non-living elements such as soil and rain also affect the species within an ecosystem
Water Cycle - Precipitation
When water is released from clouds in the form of rain, freezing rain, sleet, snow or hail
Water Cycle - Transpiration
The evaporation of water into the atmosphere from the leaves and stems of plants
Water Cycle - Condensation
Water vapour/clouds being transferred into water
Water Cycle - Evaporation
Water from the earth being transferred into a vapour/cloud
Water Cycle - Infiltration
occurs when water moves into the ground from the surface and begins to soak into the soil and rock layers underneath.
Water Cycle - Runoff
Runoff occurs when there is more water than land can absorb. The excess liquid flows into nearby creeks, streams, or pond (snow melting)
Effects of natural changes to environments on people and places – Migration
Some migration patterns are linked to climate and food availability, while others relate to breeding seasons and habitat change. The large range of migratory patterns within Australia is a reflection of the range of habitats available.
food chain
In an ecosystem, energy flow occurs in food chains, in which energy passes from one organism to the next in a sequence A simple food chain in which energy is passed from the sun to the producer, and then to the consumers.
food web
Most animals consume or are consumed by several types of organism. Each one is linked into several different food chains. These complex relationships can be described using a food web.
what would be the consequence of removing a component from an ecosystem.
When a part of the ecosystem is removed, it can lead to disruptions in the food chain. As a result, animals that depend on these species for food and nutrients will suffer.
Land managers’ understandings of specific outdoor environments –
including: public land
In Victoria the Department of Environment, Land, Water and Planning (DELWP) are responsible for the management of Victoria’s public land. (40%) including national and state parks, forests and declared water supply catchments.
Land managers’ understandings of specific outdoor environments –
including: private land
More than 60% of Victoria’s land is privately owned. Landowners, including farmers have to follow strict regulations on how they manage, and operate on their land.
Land managers’ understandings of specific outdoor environments –
including: management zones.
Parks Victoria uses 6 primary management zones, those being:
- Recreation development zone
- Conservation and recreation zone
- Conservation zone
- Wilderness zone
- Reference area zone
- Education zone
Understanding Indigenous Art (and how they impact our understandings of the outdoors).
Australian Indigenous art is the oldest ongoing tradition of art in the world. There is evidence of Indigenous rock art dating back at least 40000 years found in the Northern Territory, depicting extinct megafauna and dreamtime stories.
Understanding European artists (and how they impact our understandings of the outdoors)
In the past, Artists being white settlers to Australia have depicted environments different to what may be true. When white settlers arrived in Australia from Europe in the late 18th Century Artists were challenged by scenery which they had never seen before
Understanding Australian Musicians (and how they impact our understandings of the outdoors)
They draw attention to environmental issues, demonstrating an understanding of the need for conservation (and its practices) and the adoption of sustainable practices in the protection of our fragile environment. They use music to advocate environmental awareness
Indigenous relationships to outdoor environment - their perceptions of the land
The central focus of their existence is to care for the land. They are part of the land and it’s part of them. This view/perception is referred to as ‘custodianship’ or ‘kinship’ . They view the land as a mother.
Indigenous relationships to outdoor environments - interactions
Nomadic lifestyle: Indigenous Australians did not stay in one place, they moved around depending on the weather and the seasons. They moved inland to hunt during the colder months and towards the coast to fish during the warmer months.
Hunter Gather lifestyle: Refers to the practice of collecting food sources through hunting and collection.
Indigenous relationships to outdoor environments - impacts
Moving around did not use use up all the resources in one area,
it allowed time for the environment to regenerate and grow. They only collected what they needed making it more sustainable
Effects of natural changes to environments on people and places – Succession: Primary
Primary succession occurs after a major impact has been felt on an ecosystem, resulting in total destruction. A community will be established where it has never been before in a previously unvegetated, bare area. Coastal and rocky environments provide examples of primary succession.
