2.5, 2.6, 2.7


2.5
1. They are widespread destruction
2. Northern Australia
3. Perth, Western Australia and northern territory
4. 6
5. Hurricanes and typhoons
6. High, moist, heat, moist, spiral, tropical
7. The centre of the cyclone
8.
9. The amount of energy it has

2.6
1. 25 December 1974
2. They were the first to the disaster and set up an evacuation and medical centres.
3. A federal government body and they helped restore services to Darwin.
4. SO that there was a decreased chance in casualties from the cyclone, and that no-one got injured or hurt.
5. 80%
6. Many lessons were learnt and all cyclone-prone areas will now be better prepared as of this disaster in Darwin.
7. 29 August 2005 in the Gulf of Mexico
8. That most of the population were unable to evacuate the area as of geographical difficulties.
9. That not all of the population evacuated their area and as a result a large fraction of the residents were left without food or water when the floods affected the immediate area.
10. The NDO seems to be more efficient as the FEMA were criticised for devoting too many resources to Orleans immediately following the hurricane.
11. UNABLE TO DO.
12. a. It hit the country, and then the residents had to leave?
      b. –
13. The plane, started to rattle, at first I thought it was just turbulence. But then, it started to get extremely violent, and objects were starting to fall from all directions. Glasses were crashing on the floor, drinks were spiling and food was starting to fly. I desperately look around experiencing the shear fear on all the passengers’ faces. They were mostly adults, but there were some younger infants, who were unaware of the danger present. The population on the plane were only carrying day bags, but had travel bags under the plane. The mood started to drop and the terror on everyone’s faces increased rapidly. Then I realised, a deadly cyclone had hit Darwin… 
2.7
1. 17th march 2006 and over the Coral Sea
2. They experienced flooding, torrential rain and strong winds
3. Roads, rail and air transport and left people stranded
4. AU $350 million
5.
6. Emergence management Australia and state emergence services
7. Government agencies, local councils, state emergence services, energy suppliers
8. They ran community workshops to help people prepare
9. Queensland government
10. Large quantities of resources needed to remove danger and repair the damage
11. It would have significantly decreased
12a. 300km
12b.
12c. 1am March 21 it means it isn’t as strong as a cyclone
12d. 500 km

mapping

  1. What is it about the pressure system stalled over Australia that relates to the weather over the next 4 days?

    There are high pressure systems over Australia, resulting in the weather to be in a stable condition, with partly sunny days, predicted with no rain. 
  2. What is the air pressure in each of the next 4 days for each of the capital cities? How does this correspond with the predicted weather for these cities
SYDNEY: High air pressure systems, being Mostly sunny 
CANBERRA: With not as high air pressure, it would most be partly cloudy
PERTH: With a high pressure from both directions, would be relatively sunny, but cloudy 
MELBOURNE: With very high air pressure, would be fairly sunny and dry for the 4 days





  1. What is the contour interval (sometimes abbreviated CI)? Convert to metric.

  1. What is the scale of the map? Convert it into the metric system
20-1
  1. What is the gradient of the line? Calculate in metric system.
2-3


2.8

2.8
1. 1012
Ii 1010
Iii. 102
Iv. 1018
B. Hobart
C. there will be some strong winds and some expected shower
Di. Low pressure and isobars decrease
ii ?
Iii low pressure
E. Hobart closer to the center of the air pressure

2.2

1. A landslide is the movement of mass of rock of sections of the Earths crust under the force of gravity
2. Terrential Rain, undercutting from waves of rivers and Earthqueakes
3. When the humans have radically altered the shape of the land
4. Movement of tectonic plates, using a Richter scale
5. Earthquakes is the intra-plate tension where movements occur along cracks and faults in the Earths crust
6. Every 15 months, the epicenter of these earthquakes aren't near the mainland of Australia
7. 5.6 on Richter Scale. killing 13 people and injuring 120. 35.000 hims and 3000 other buildings being damaged.
8. Landslides, move the earth on the exterior of the environment whereas earthquakes shake the interior of the crust.
9. The movement of the ocean bottom displaces water on the surface.
10. Earthquake, landslide, or volcano
11. An undersea earthquake is usually formed, it causes disturbance under water, resulting in large waves  in all directions of the disturbance.
Sudden shifting of the continental plates causes earthquakes, forcing sea water to move and large waves. It moves quickly to mainland and can cause disastrous damage
12. Sudden retreat of water - you fell earthquake - and massive water ROAR
Shake - Drop - Roar
13. It was caused by an undersea earthquake
14. 23 in Australia, took 20 mins for the Indian ocean tsunami
15. water retreats and water is compressed
16. They have developed a tsunami warning system
17. He is a uni- geoscientist professor and has warned the tsunami triggered by New Zealand
18. a) 0 N 90 E
      b) 4hrs 10hrs 5hrs 9hrs
19. IT WAS A SAD day for Thredbo. An earthquake of immense magnitude, hit the snow last weekend. Many were shocked by the sheer power of it. Injuring many of the residents.
