Outdoor Ed Sac 1 Flashcards
Define hypothermia
A dangerous condition in which the core body temperature drops below 35 degrees
Define biodiversity
The variety of all life which forms the different plants, animals and microorganisms, the genes they contain and the ecosystems in which they form a part
Define community
A group of interdependent plants and animals inhabiting the same region and interacting with eachother.
Factors affecting outdoor Ed
Geology
can be seen in the rock material found in a particular location, soil characteristics and drainage.
Eg - we know that Australia is a fairly flat grounded place but does have some high peaks eg - airs rock
Factors affecting outdoor environments
Climate
Annual rainfall, extremes in temperature and average daylight.
Eg: Australia had four seasons
Summer, autumn, winter and spring
Factors affecting outdoor environments
Position and aspect
Southern aspect is usually shade, greater levels of soil moisture and lower temperature overall.
Northern aspect is usually result in drier soils, warmer temperatures, lots of sunlight.
Eg- mitchell river it’s more about the two aspects in the same spot interacting together.
Alpine
High Rocky Mountain areas
Snow covered area of the Australian alps and Tasmania
Alpine - distribution (facts)
500,000 hectares in the east and northeast state
0.5% of mainland Australia is truly alpine
Alpine- biodiversity and flora and fauna
Typically vegetated by Heath, herb and grass species
Snow gums and baw baw frog
Alpine - human influence and threat
Ski resort
Water catchment pollution
Coastal area
An area lying at the interface between land and sea.
Distribution facts about coastal
Victorian has 200,000 kilometres of coastline.
There are 123 bays and inlets varying in size
Climate for coastal areas
Costal environments are located in flat landscapes
Rainfall from 100-1200 millimeters per year
Coastal flora and fauna
Sea grass meadows
Wide variety of fish, sponges and large sea animals live here
Human influence and threats to coastal
Urban development
Ground nesting, small birds and mammals are threaten by these problems
Grasslands
Large area of land covered in grass
Large area of country land
Distribution facts about grasslands
Less than 10% of natural tree and shrub cover
Found in north and western parts
Elevation and climate for grasslands
Medium rain fall of 400-1000 millimeters per year
Flat landscapes
Flora and fauna for grasslands
Stumpy tail lizards
Brush stone curlow
Human influence and threat to grasslands
Bush fires
European settlers cropping the land
2 recreational users understandings of outdoor environment
Safety
- plannings / preparations
- Emergency plans (someone hurts them selves)
- medical (first aid)
- appropriate clothing (weather conditions)
- weather conditions (is it safe)
- RISK ASSESSMENT
- knowledge of the outdoors
Sustainable interactions
- minimal impact (leaving no trace, rubbish)
- facilities available (tolieting)
- sensitivities of flora and fauna
- cultural significance (protection, respect)
4 different types of heat loss
Conduction- heat passes through a cooler object. Eg: ground, snow.
Convection- heat rises away from the body and into the air. Eg: windchill
Evaporation- heat is lost due to sweat through perspiration.
Radiation- Heat passes through a cooler environment. Eg: water
How to reduce the risk of hypothermia
- Layering up making sure you have the right material of clothing to keep you warm.
- drinking hot liquids and eating hot.
Layering system
Base
Mid
Outer layer
Base - moisture management is the first layer that is in direct contact with your skin.
Mid - insulation layer - second layer of clothing it retains body heat
Outer layer - protecting from wind, and moisture like the rain and snow.
Getting rid of body moisture
