The Earth’s surface is ever changing, and each region has different rates of change (Westaway, 2017). This is completed through lateral transport processes such as water, wind and mass movement, while ice is one too it doesn’t apply in Australia. Mass movement happens on sloping ground where huge slabs of the ground surface detach and slide or flow downhill (Government of South Australia, 2016). It occurs in Australia due to the extreme wetness causing the soil to be weak and gain mass, or by earthworks such as track cutting. Slope plays a key role in mass movement and virtually any slope steeper that 30% is at risk. South Australia is home to permeable substrate materials, shale, bedrock and depending on
Water is the most relied upon resource on earth and if it disappeared life could not and would not exist on this planet. So if one of our main sources of water in South Australia, The Murray Darling-Basin, becomes unusable then we would need to find the problem and do everything possible to stop it or counteract it. This report investigates on salinity in the Murray Darling-Basin, using the issue question “Is there enough being done to counteract the effects of salinity in the Murray?” as the focus. Salinity is a key significant environmental challenge which the Murray faces and if left unmanaged it could cause serious implications for water quality, plant growth, biodiversity, land productivity, infrastructure and could lead to a loss of a water source that’s critical to human needs. In this investigation five different aspects of this salinity issue are presented and these aspects include what Salinity is and how it has become an issue, what the effects are, how salinity affects the rest of Australia, what can be done and is anyone doing anything and finally what the visions are for the future of the Murray and its salinity levels.

Skiing is a sport enjoyed by millions of people around the world. The adrenaline rush that skiers get from flying down the slopes is unmatched, but all too often the cause for this rush is overlooked. Physics plays a crucial role in skiing and without it, there would definitely be no skiing. The concept of skiing is simple. You attach a ski to each foot, go to the top of a hill or incline, and slide down, turning side to side. From this basic concept of sliding down an inclined plane, a worldwide sport has evolved. In this paper, I hope you gain a useful knowledge of the vitally important role that physics plays in the sport of downhill skiing.
Canada is a great place to live. Winnipeg… is good enough. Winnipeg is known for its diverse population, festive multiculturalism, beautiful architecture, vast prairie land and The Jets. One thing Winnipeg is definitely not known for, being a geological hazards hot spot. These hazards are geological events that take place, which have an impact on civilization. Canada is impacted by a wide scope of events ranging from earthquakes to fires. However, Winnipeg is lucky to be conveniently located away from any seismic activity, any threat of coastal dangers, any mountain risks and lastly it is absent of even the slightest volcano. Therefore, what Winnipeg lacks in attraction it makes up for in safety. In spite of its perceived security this major Canadian city is unfortunately prone to some very serious dangers. It is home to very cold, lengthy winters, dreadful storms that lead to wet springs. Scientifically speaking “geohazards are any geological or hydrological process that poses a threat to people and/or their property” (Bilderback, 2013). Thus, the geological hazards that will be discussed in this paper are flooding, landslides, and severe weather including tornadoes and storms.
Leading scientists advise climate change will cause increases to the frequency and intensity of extreme weather events. Rising sea levels pose a significant risk to coastal communities, while the world’s oceans could become too acidic to support coral reefs and other calcifying marine organisms. Coral reefs contain only six per cent of the area of the Great Barrier Reef, yet they provide critical habitat and food for numerous species in the ecosystem. However, climate change has already impacted coral reefs in the Great Barrier Reef as corals are very helpless against its potential impacts. Eight mass coral bleaching events has occurred since 1979, triggered by unusually high water temperatures. And because of this, zooxanthellae (photosynthetic algae) leave their tissues and corals will have no more colours hence ‘bleaching’. Without the zooxanthellae, the corals that remain gradually starve to death. Once the coral dies, fish and a multitude of other marine species are soon affected. Rising sea levels and more frequent and intense storm surges will see more erosion of Australia’s coastline, causing community and residential
It all started in 1859. Australia was slowly becoming populated with European pioneers who sought the newness of the great, unsettled continent. However, there were a few things from home from which they just couldn’t part.
Semaphore is a classic Adelaide beach supporting many facilities. However, this would not be the case if coastal management was not put into progress. Coastal management is a way of supporting the world’s coasts, by using many techniques from construction of structures in which prevents wave energy from reaching the shore to planned strategies. Factors of this includes; rising sea levels, erosion, long and short term drift, sand movement and marine biology. The importance of coastal management is quite significant as it will help to prevent coastal erosion. In addition to this, without coastal management the world will be affect economically, environmentally as well as socially. Without the strategies involving the management of the coast,
Decreasing rainfall and exterior reservoir recharge since the mid-1970s in Western Australia have been related to fluctuations in atmospheric circulation that are constant with what would be predictable in an atmosphere subjective by rising greenhouse gas intensities. The Water Corporation of Western Australia is focusing the lessening surface water resource by setting out to distribute a ‘climate-independent’ reserve of water for domestic

Australia is home to the great barrier reef which is the world's largest coral reef system, and home to the kangaroo. Australia is the driest continent in the world. The outback is the part of Australia that few live in because it’s a vast desert (“Australia”). The great dividing range is a long chain of mountains that runs along the Pacific Coast of Australia (“Australia”). Australia is the driest inhabitable country in the world (“Australia”). The great barrier reef of Australia is the largest in the world (“Australia”). Australia is already a dry country and if the temperature rises anymore due to climate change than Australia could suffer from more severe forest fires and be doomed.
There are a few different physics engines that programmers use now for their games. There are 2 main physics engines that programmers use: Havok, and Math Engine.

The Relationship between the Angle of Elevation of a Ramp and the Speed of a Ball
Each part of Australia has its own unique combination of weather systems that produces severe bushfire conditions, but in all cases these conditions result from hot, dry winds blowing from Australia's central arid region.
Here, we can use the vectors to use the Pythagorean Theorem, a2 + b2 = c2, to find the speed and angle of the object, which was used in previous equations.
