Australia's population

1. The study of statistics such as births, deaths, income, or the incidence of disease, which illustrate the changing structure of human populations
2. 2002/2003. By 2050 the population is expected to meet 42 million
3. 315 000
4. Decrease in predators and increased food resources. I think that these reasons for increase are bad examples for a first world country like Australia, so none of these could really be attributed to the percentage of population in Australia.
5. 1.78
6. 2.1. This compares as being very low compared to later years after WWII were the population literally exploded because of the peace people had because of no threat of war.
7. Declining and is almost starting to plateau
8. 2.6 people per house for Australia. 2.95 people per house for the USA

How has Australia changed in my life time

List some of the ways Australia has changed in my life time

Physical Changes

1. In my local community, Galston, a new shopping centre was added next to the already existing Galston Village, which had already contained a plethora of stores and restaurants. This new shopping centre was built over an old car park used for the village. It contains a franklin supermarket and a pharmacy, and was probably not necessary for the village. It looks nice and is useful for its pharmacy, but most store spaces there are still empty and available for lease , years after it was opened!
2. In my local chopping centre, Castle Towers Shopping Centre, the old movie theatre, Greater Union, was bought and replaced by Event Cinemas. They completely refurbished the older theatre, added the Vmax (A larger, less comfy version of Gold Class) and put in a Gold Class option. This has been a good change as it has brought the movie theatre into the modern world and made viewing moves more enjoyable.

Socio-Economic Changes

1. The price of Petrol has definitely gone up in the past couple of years based on the recent GFC (Global Financial Crisis). Following the crash of the stock market and many major banks in America, the Australian Dollar careened lower compared to other currency's and the petrol prices soared, causing many problems for struggling families and teenagers learning to drive.

Cultural Changes

1. In recent times people from foreign countries such as Pakistan and Indonesia have been trying to sneak their way into Australia by means of boat. Some have succeeded, but most have just been let into the country and been given food, water, shelter and VISA's, all for free! Many people have gotten up in arms about this, as they see this as the government feeling bad for these people and giving them free housing, and this has caused a lot of problems for Julia Gillards labour government. 

Group Member Evaluation

Sebin Han.

Sebin joined our group later on and has been a consistently hard worker since then. Sebin as been a pleasure to work with and helped us all with the information required to complete our maps. Sebin was in charge of the El Nino and La Nina fact sheets and I believe has done a good job explaining the two weather conditions and two natural disasters caused by this.

Jake Hanlon

Jake was my original partner and has been with me from day one. He took on the role of making the two maps of La Nina has has done a fantastic job with those two. He has been a pleasure to work with and has completed his maps efficiently and effectively, explaining the effects of La Nina to Australia and the World in detail.

Concerns.

On Wednesday I was not able to come into contact with Sebin or Jake, and that led to some confusion

Study Questions

1. How many hectopascal (hPa) is the high over the Eastern side of Australia?
1032 Correct 
2. What LARGE part of Australia is experiencing rain?
Western Australia Correct
3. Give the approximate location of the centre of the high on the east coast?
37 S 141 E (Use Latitude and Longitude describing locations)
4. How would you compare the speed of the wind for Australia to New Zealand?
The wind speed in New Zealand is much higher than in Australia 1/2 Right (The isobars are closer around New Zealand, so the wind speed is higher)
5. What month has the warmest temperature?
July Wrong (Red line at the top of chart is temperature) Correct Answer = May
6. What hemisphere is this city in?
Southern Hemisphere
7. What month has the highest rainfall?
July Correct
8. What is the average temperature and rainfall for November?
27.5 Degrees (Temperature)  80 mm (Rainfall) Correct
9. What latitude do you think this city is at? Why?

Questions 2.5

1. Tropical cyclones are intense low-pressure systems that form over warm oceans.
2. Tropical cyclones usually form over the northern areas of Australia.
3. Western Australia and the Northern Territory
4. 6
5. Hurricanes and Typhoons
6. Tropical cyclones develop in the tropical regions of the world. Heat from the sun causes warm, moist air to rise into the atmosphere. As the air rises, a low pressure system forms and condensation occurs, which releases latent heat causing the air to rise further into the atmosphere. If the air pressure in the upper atmosphere is high, then the rising column of warm air will spiral outwards in the upper atmosphere and air will rush from the surface to replace it, forming a tropical cyclone.
7. The eye of a cyclone is the centre, and is usually calm with a clear sky.
8. When a tropical cyclone moves away from the tropics and into cooler oceans they start to lose energy as the hot air dissipates, and so they are downgraded to tropical storms. 

Questions 2.4

1. A flood is when water inundates land which is normally dry.
2. Flash flooding is when small river or streams are unable to cope with all the water all at once so they overflow and flood. Urban areas are not normally prepared for flooding or flash flooding, and so can suffer greatly.
3. Inland rivers- These are subject to flooding which often covers thousands of square km's and can be devastating for farmers and their crops. Coastal Rivers- These floods are short and fast flowing, and they generally only last for a couple of hours or days.
4. Houses could be destroyed. People could be killed. Produce could be washed away or destroyed.
5. Water had already filled the rivers and catchments around Katherine, so almost all the water overflowed and flooded Katherine.
6.  Economic- 500 Business's we're evacuated or destroyed. Environmental- Crops would have washed away. Social- 4 people died.
7. A) Inland Catchment- slight gradient  Coastal Catchment- steep gradient. B) Slight Gradient to Steep Gradient. C) The water would run towards the steeper gradient, because when it is flat there isn't anywhere to go.
8. Dams are normally used to control the amount of water in a river or catchment and can also supply water to an area. Dams influence inland river because they keep the water level under control, but if they overflow could also cause the river to overflow, causing a flood.
9. The flood came in faster than I could have imagined. I wasn't ready as it swept down the streets, quickly filling up the first floor with muddy water. I couldn't get to my car for it was underwater. I ran out onto my balcony and saw the town square flooded, with water gushing down the streets. It was sweeping down the street, washing cars and people away.
