Select two names that resprents the input of a non-linear response
Select three human use of litosphere
Select three alternatives of oil for the future in Australian mining
Megafuana are extinct animals that weighed over
Select the impacts of El Nino
Select the impacts of La Nina
What was the global average tempreture difference between the last ice age and now?
What formal geoglogical epoch is the Earth currently in?
How long ago did Earth enter into the holocene?
Select three time periods scienctists debate when Earth entered into the Anthropocene
Define a linear response
Inputs and outputs that vary around a stable average
In lake Purrumbete, which is the deepest fresh water lake in Victoria. What fish are at threat due to tempreture increase?
What is the thermal temparture for Brown Trout?
Define a non-linear response
A non-linear respone is when the systems behaviour results in a very different outcome and results in tipping points.
Define in three points why a non-linear is hard to reverse using an example of nutirent build up resulting to algae.
1. Plants die, therefore their roots no longer bind the sediment
2. The sediment then enters into the water column
3. The sediment is the blocking the sun penetration
4. Results to seeds not growing
Select the three main soil types in South Australia
State 5 types of vegetations
1. Decidous forest
2. Conifer forest
3. Desert
4. Grass land
5. Rainforest

What is the percentage Australia holds of uranium deposits in the world?
Select the percentage of Australia's readily exploitable deposits
How many uranium mines are there in Australia?
What is the current protections in place for mining on a national level?
The Commonwealth Environment Protection and Biodiversity Conservation Act, 1999, in effect since July 2000
What protections are in place for minining in South Australia?
The South Australian Development Act, 1993, in effect since January 1994
What is the percentage of conservation protection in Australia?
How many ice ages has there been in the past 1 million years?
Carbon dioxide is at the hightest point over how many years?
What is the percentage of engery that is transfered in the atmosphere?
What governs rainfall on a regional scale?
- Circulation patterns
- Sea surface temprature
- Orographic rainfall
- Continentality
