What is a Disaster:**
 * Week 2: media type="custom" key="6414479" width="222" height="188" align="right"
 * A disaster is something that can affect the world in a dangerous or a least dangerous.**
 * EG: I spilled Tomato Juice on my top is a Disaster that has not affected the world **
 * EG: An Earth Quake has killed thousands of people is a disaster that has affected the world. **
 * What Are The Different Types Of Natural Disasters: **

** Volcanos, Earth Quakes, Tornados, Hurricanes, Avalanche, Bush Fires, LandSlides, Floods, Sink Holes, Blizzards, Storms, Lightning ** media type="youtube" key="zQb_lYKoCL4" height="385" width="480" align="right"
 * These are some of the different types of Natural Disasters: **
 * And Many More. **


 * What Natural Disaster Do I Think Is Most Dangerous: **


 * I think a Earth Quake is the most dangerous Natural Disaster because if you are in your house and a Earth Quake starts you can’t really escape. Also Earth Quakes can make heaps of people have no food and become homeless. Earth Quakes can also make your house become destroyed and then you will have no where to live. That is why I think Earth Quakes are the most dangerous Natural Disaster. **


 * Week 2 Reflection: **
 * This week I learnt **

How to create my Wiki’s and how to put widgets on.
 * I also learnt that Tsunami’s slow down when they get close to land but they can still cause a lot of damage.**
 * I also learnt about how Volcanos erupt and how much damage they have caused.**


 * Week 4: **
 * What Do We Use To Classify Disasters?: **


 * We use this special tool called a Ricta Scale a Ricta Scale measures how Earth Quakes can make the ground shake and how much damage an Earth Quake would have caused. **

** Week 4 reflection: ** **Week 5:**
 * This week I have learnt a lot about Typhoons and Hurricanes and how they can affect the world. I have also learnt how to put pictures on my Wiki’s page. Also I have learnt a lot about Volcano’s and what type of lava there is inside a Volcano.**

What Are The Layers Of The Earth’s Structure: The Earth consists of several layers. The three main layers are the core, the mantle and the crust. The core is the inner part of the earth, the crust is the outer part and between them is the mantle. The earth is surrounded by the atmosphere. Till this moment it hasn't been possible to take a look inside the earth because the current technology doesn't allow it. Therefore all kinds of research had to be done to find out, out of which material the earth consists, what different layers there are and which influence those have (had) on the earth's surface **.


 * What resources do we use from beneath the earth? **
 * Some Things we get between are Earth’s surface are: **


 * Oil **
 * Minerals **
 * Gas **
 * Gold **
 * Brown And Black Coal media type="custom" key="6416745" width="326" height="242" align="right" **
 * Tin **
 * Nickel **
 * Copper **
 * And Much Much More. **

This Week I Learnt: **
 * Week 5 Reflection: **


 * That some Natural Disasters are more dangerous then others. I also learnt that Earth Quakes can kill up to 1000 people and they **** can leave people homeless and Earth Quakes can happen all over the world. **

The atmosphere is divided into five layers. It is thickest near the surface and thins out with height until it eventually merges with space. **
 * What are the different atmospheric layers above us? **

2) Many jet aircrafts fly in the stratosphere because it is very stable. Also, the ozone layer absorbs harmful rays from the Sun. 3) Meteors or rock fragments burn up in the mesosphere. 4) The thermosphere is a layer with auroras. It is also where the space shuttle orbits. 5) The atmosphere merges into space in the extremely thin exosphere. This is the upper limit of our atmosphere ** What effect does the sun and moon have on the Earth? ** Energy from the sun affects many things on earth. One of the main things the Sun does is warm our planet, including the atmosphere. This energy drives much of our weather. The solar circle, the rise and fall of the number of sunspots on the Sun, has been known since the mid 19- century. Soon after this discovery scientists started to ask how the solar cycle might affect the Earth's weather. **
 * 1) The troposphere is the first layer above the surface and contains half of the Earth's atmosphere. Weather occurs in this layer.

The Earth is unique amongst the terrestrial planets in having a large satellite, the Moon, which, relative to the Earth, has the largest mass of any satellite - parent system. Numerous lines of evidence indicate that the Moon was derived from the Earth as the result of a singular impact event soon after the initial formation of the Earth. As a result the subsequent evolution of the Earth and the emergence and development of life, has been strongly influenced by the presence of the Moon.


 * Week 6 Reflection: **

About Tsunami’s and how they can affect people and places. I also learnt that typhoons are just like hurricanes but typhoons are in water. I have also found out that Volcano’s lava can come out of a Volcano fast or slow but it depends how runny the lava is. ** Week 7: ** What Is in Our Solar System That Can Affect Us? **
 * This Week I Learnt: **

The sun and the moon can affect us.
 * Also if a meteorite hit the earth then there will be many tragic deaths. **
 * Little rocks and dust create meteorites and that is how meteorites come and hit the Earth. **


 * Week 7 Reflection: **


 * I learnt a lot especially after the C.S.I.R.O had came and talked to us. **
 * Here are some of the things I have learnt from the C.S.I.R.O coming to see us. **

There are three different types of rocks that come out of a volcano puma, Basalt and obsi ** Week 8: ** How do humans affect nature? ** Cutting down trees **
 * There are three different types of waves that can make the earth move there is primary waves that go up and down and there is secondary waves which move side to side. **
 * There are more Earth Quakes that happen around tectonic plates then in the centre of the earth. **
 * I also learnt that all of the Earth’s tectonic plates fit together. **
 * Humans can affect nature in all different ways such as: **
 * Killing animals and make them become extinct **
 * Killing whales and other animals in the sea just so they can eat them. **
 * Dropping rubbish on the ground just so an animal can come by and eats the rubbish and then chokes **
 * Dropping stuff in the ocean and killing the sea creatures in the ocean. **

Humans can cause all different problems such as cutting down trees and polluting the area but one thing that is causing problem is land problems there are too many people in Australia and that is how humans cause problems from use of land problems also if there are to many people in Australia than it will get so crowded and people will try and find a way out of this problem and cause many many big problems. **
 * How has human use of land caused problems? **

This Week I Learnt: **
 * Week 8 Reflection: **
 * That cyclones and hurricanes are given names E.G Cyclone Tracy **
 * I also learnt a lot about the Solar System like how many moons Pluto has and that the milky way has 5 billion stars. **
 * Also a lot of Volcano’s happen around tectonic plates. **
 * And Tsunami’s waves can get up to about 10 foot **
