=​​ Welcome to Lachlan's disaster page = =media type="custom" key="6126415" media type="custom" key="6155843"= =week1= __reflection__

i have learnt some new disasters like typhoon, sink hole and tsnamie. Also i have learnt that the richtiscale go's up to 10.00 and volcanoes can go to sleep for 100's even 1000's of years.


 * 1) how do tsnumies happen?
 * 2) how do sinkholes start?
 * 3) does thunder come before lightning?

= = = = = = = Week 2 =
 * 1. Different natural disasters are... 2.what is a disaster 3 . which natural disaster is the worst

2.A disaster can be a little problem like if you drop a glass bottle that is a disaster, but an other one is it can be life loss if you fall of a building or drown and all sorts of things. An other one is that a disaster can have an affect on your life like you lost most of your money or your house got on fire and heaps more.
 * earthquake
 * whirlpool
 * sandstorm

> It is not fully understood about how exactly tornadoes form, grow and die. Tornado researchers are still trying to solve the tornado puzzle, but for every piece that seems to fit they often uncover new pieces that need to be studied. > >  > > >  == =WEEK 4= >
 * cyclone 3. I think that the worst natural disaster is the volcano because the ash can kill you, the lava can kill you and the smoke
 * bushfire kill you aswell.
 * volcano
 * tornado
 * tsunami
 * typhoon
 * sinkhole
 * **How do tornadoes stop?**

The mantle is to divide into the inner mantle and the outer mantle. It is about 1,800 miles(2,900 km) thick and makes up nearly 80 percent of the Earth's total volume.

__The crust__

The crust lays above the mantle and is the earth's hard outer shell, the surface on which we are living. In relation with the other layers the crust is much thinner. It floats upon the softer, denser mantle. The crust is made up of solid material but these material is not everywhere the same. There is an Oceanic crust and a Continental crust. The first one is about 4-7 miles (6-11 km) thick and consists of heavy rocks, like basalt. The Continental crust is thicker than the Oceanic crust, about 19 miles(30 km) thick. It is mainly made up of light material, like granite.

= __The core__ =

The inner part of the earth is the core. This part of the earth is about 1,800 miles (2,900 km) below the earth's surface. The core is a dense ball of the elements iron and nickel. It is divided into two layers, the inner core and the outer core. The inner core - the center of earth - is solid and about 780 miles (1,250 km) thick. The outer core is so hot that the metal is always molten, but the inner core pressures are so great that it cannot melt, even though temperatures there reach 6700ºF (3700ºC). The outer core is about 1370 miles (2,200 km) thick. Because the earth rotates, the outer core spins around the inner core and that causes the earth's magnetism.
