=Welcome To Alis Page Of Disasters .= media type="custom" key="6020181" align="left" width="70" height="70" =WEEK 1 =

This week i have learnt how to put pictures onto my wiki page but before i learnt to make my wiki page. I learnt that the earth takes a year to do a full rotation of the sun. I learnt that gravity is the most powerful thing in the universe. The moon is very important! i have also learnt that Mr.Farrell has put on a movie page for us to watch and learn more about natural disasters. During class we have discussed the seasons of the year and how they are very important.

__Question:__ What forms a twister and how does it start off?

​

__Mr Farrell's question - "What do you think is the most dangerous Natural Disaster" __
I think that all natural disaster are the most dangerous because they can effect lots of lives around the world. Most people that get caught up in a storm, earth quake etc are left with out any homes, food or even water! = WEEK 2 = This week i have learnt how to put a voki on my wiki page and we discussed what is the most dangerous natural disaster.

A disaster or natural disaster is where the earth creates something not man mad and is not able to be by man. Some disasters destroy so much that there is almost nothing left depending on what disaster occurs.

 =WEEK 3 =

media type="custom" key="6053985" =WEEK 4 = This week I have learnt how under the crust of the earth is these stone plates [not the ones we eat off]. They look a bit like a jig-saw puzzle and when crash into one another they form an earthquake and lavare bursts up

to the top of the earth. i also learnt that the core in the earth is hotter then the surface of the sun.

**__WHAT DO WE USE TO CLASSIFY A NATURAL DISASTER?__ **
We use a righter scale to measures the power of an earthquake. =__How are they measured?__ =

The Richter magnitude scale measures the amount of seismic energy released by an earthquake. This scale is measured up to 10. ​ =WEEK 5 = This week i learnt about the solar system and where all the planets are.I also learnt that there is 4 rock planets and 4 gas planets, earth is one rock planets.
 * __What are the layers of the earths structure?__**
 * Atmosphere
 * Earths crust
 * Mantle
 * Outer core
 * Solid metal inner core


 * __What are resources do we use from beneath the earth?__**
 * Oil
 * Cole
 * Petrel
 * Gold
 * Rocks

=WEEK 6 =

This wee k i learnt about all different types of volcano's like sputter volcano which catapult balls of lavar into the air. I also learnt about the layers of the earth [as you can see from the diagram in week five.] In a Roman, seaside town of Pompeii a volcano erupted at least 8km away from the town.The reason why so many people didn't get away is because of a poisonous gas that came from the volcano, but they also got killed by the ash that had been carried by a big cloud.

__What are the different atmospheric layers above us?__
[0-12km] [12-50km] [50-85km] [85-600km]
 * Troposphere
 * Stratosphere
 * Mesosphere[[image:planet_earth.jpg width="173" height="181" align="right"]]
 * Themosphere

What effect does the **sun** and the **moon** have on the **earth**?
SUN MOON [Sun and moon pull the tides in and out with a gravitational pull that gives it the greatest effect] =WEEK 7 =
 * warm our planet, including the atmosphere.
 * weather [wind]
 * ocean tides

===**This week we have learnt whether the earth goes around the sun or the sun goes around us but the truth is the sun don't move, the earth goes around the sun on it's tilt. We also found out that Uranus rotates around the sun revolving.**===

How can comets, asteroid's and meteorites affect us?
These pieces of flying rock can affect by hitting the earth and wiping out the whole human race just like what some people believed wiped out the dinosaurs!

=WEEK 8 =

This week I learnt about the Planet Pluto. I learnt that on Pluto, it is -230o meaning it would be so cold that it could freeze rock, i also learnt that Pluto was going to be one of Neptune's moon's but escaped Neptune's pull of force. Now scientist are calling Pluto a __planet-torem__. In stead of orbiting the sun in a circle Pluto orbits the sun in a sort of oval shape.

We humans affect nature by
 * How do humans affect nature?How has human use of land caused problems?**


 * useing up alot of water
 * mineing for oil [e.g. the oil spill in the golf of Meico]
 * bush fires can be lit

=How are humans trying to reduce the effect on NATURE?= We are trying to reduce it by not using cars as offeren, not knoking down as many rain forst and trying to fix our mistakes from the past.
