**__WEEK ONE __**
This term we are learning about Natural Disasters. So far we haven't done much about Natural Disasters.This term I have learnt that the moon helps us stay alive and it takes one year for the earth to travel around the sun. Also how to use wikispaces INFORMATION ABOUT SOME OF THE NATURAL DISASTERS TSUNAMI'S A Tsunami is caused by a large body of water, such as an ocean or a large lake. Tsunami are a frequent occurence in japan; approximately 195 events have been recorded. Tsunami's can destroy coastal cities and the wave is faster than people can run. Earthquakes, Volcanic eruptions, other under water explosions and land slides. Also other mass movements and other disturbances above or under the water, all have the potential to start a Tsunami. EARTHQUAKES An Earthquake is when the grond of the earth cracks. Also an Earthquake is a result of a sudden release of energy in the earth's crust. QUESTIONS 1. How does gravity work? 2. Does anywhere in the world get 12 hours of day light and 12 hours of dark? 3. What is the moon made up of? 4. What causes Tsunami's? 5. What causes Tornado's (Twister)?

 This week I have learnt how to add a voki into a wiki page and how to add a youtube video in. Also I learnt that under a volcano melted rock moves around like thick syrup. The melted rock is 9 times hotter than boiling water. The deeper you get down into the crust the hotter it gets.

Thunderstorms are the most powerful elctrical srorms in the atmosphere. In 20 minutes, a single thunderstorm can drop 125 million gallons of water and produce more electrical energy than is used in a large city during an entire week. Each, year there are about 16 million thunderstorms around the world. Every minute, thousands of newly formed thunderstorms sweep across the earth's surface and lightning bolts flash 100 times a second.

Thunderstorms form when moist air near the earth's surface is heated by the sun. Like a bubble in water, the warm air rises until it reaches a layer of cool, dry air, where the moisture in the air condenses into tiny water droplets that form puffy cumulus clouds. In minutes, the cloud may grow several miles wide and 40,000 or more feet high. Strong winds shred and flatter the cloud top into tha farmiliar shape of "thunderhead" or cumulonimbus cloud. = __What Is A Disaster?__ = =A disaster is something that can kill alot of people and can destroy cities like when the victorian bushfires in 2009 destroyed kinglake and many more areas. Also it killed alot of people. A man made disaster is like when say I put a tree on fire in a bushy area and started a bushfire. A natural disaster is when people dont start the disaster like a tsunami. A hybrid disaster is when a disaster is followed up by another disaster. = = __What are the different Types of disasters?__ = = 1.Cyclone = = 2.Tornado = = 3.Tidal Wave = = 4.Tsunami = = 5.Avalanche = = 6.Earthquake = = 7.Water Twister = = 8.Dust Storm = = 9.Rain Storm = = 10.Bushfire = = 11.Flood = = 12.Lightning = = 13.Landslides = = 14.Blizzards = = 15.Hailstorms = = 16.Mudslides = = 17.Meteor Shower = = __What is the most dangerous Disaster?__ = = I think a Tsunami is the most dangerous disaster in the world!!!!! I think this because Tsunami's kill hundreds of people and destroy cities. After a Tsunami it can cause a flood and the water can get into people's houses which destroys the house so the have to live somewhere else but if all of their friends houses couldve been destroyed aswell so there is no where else to go really. = = THATS MY OPINION!!!!! = ==media type="youtube" key="a-8_wEm7t8k" height="385" width="480"media type="youtube" key="AlPqL7IUT6M" height="385" width="480"media type="youtube" key="boqAxCOxGqQ" height="385" width="480"media type="youtube" key="IJGE51oBAms" height="385" width="480"== =WEEK 3 = =This week we don't have any homework because the grade 5's are on camp!!!= =WEEK 4 =

== This week i have learnt alot of things about Natural Disasters. I have learnt that inside the core is hotter than the suns surface. Also in the centre of he earth there is something called a core which is really strong and no one ever has gotten through it. Inside the core there are Titonic Plates which are floating on top of lava. The lava gets into the volcanos by the lava traveling through the cracks of the core. ==

WEEK 5

__Landscapes: The changing scenes:__
==**Landscapes on the world have been mainly made by the action of weather on rocks. For thousands of years mountains have been worn by wind, rain and ice. Natural vegetation can be cleared by farmers to plough fields and grow crops where the soil and climate is suitable. Climate variations are recorded in the landscapes they have formed.**==

__Soil:__
==In places where the ground is frozen for most of the time, soil is formed very slowly. Near the equator where the climate is warm and wet, soils form rapidly and are said to be ancient. The best farm soils are mollisols of the prairies and steppes, and spodosols of temperature forests, found in North Eastern North America.==  **
 * What are the layers of the earth's structure?

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 ball of elements that are iron and nickel. It is divided into two layers, the inner core and the outer core. The inner core which 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 1,370 miles (2,200 km) thick. Because the earth rotates, the outer core spins around the inner core and that causes the earth's magnetism.
 * **The Core ** ||

**__Inner core:__ ** It is 3,200 - 3,960 miles (5,150-6,370 km) below the earth's surface and mainly consists of iron, nickel. The temperature in the inner core is about 9032 to 10832 ºF (5000-6000 ºC). Because of the high pressure, the core is solid. **__Outer core:__ ** The outer core is 1,800 to 3,200 miles which is 2,890-5,150 km below the earth's surface. The outer core is liquid and mainly consists of iron, some nickel and about 10% sulphur and oxygen. The temperature in the outer core is about 7200 to 9032 ºF (4000-5000ºC). The outer core and inner core together cause the earth's magnetism.
 * <span style="background-color: #000000; color: #0000ff; font-family: Impact,Charcoal,sans-serif;">What does the core consist of? **

<span style="font-family: Impact,Charcoal,sans-serif;">The layer above the core is the mantle. It begins about 6 miles(10 km) below the oceanic crust and about 19 miles (30 km) below the continental crust (see The Crust). The function of the mantle is to separate 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. Science deals with the structure of the mantle in two different ways. One way is based on its chemical construction (the material), the other on the way layers stream or move.
 * __ **<span style="background-color: #ffffff; color: #000080; font-family: Impact,Charcoal,sans-serif; font-size: 120%;">The Mantle ** __ ||

**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.

<span style="background-color: #000080; color: #ffffff; display: block; font-family: 'Arial Black',Gadget,sans-serif; font-size: 150%; text-align: center;">WEEK 6 **__ REFLECTION __** There are five different types of Volcanoes and they are Composite, Shield, Cinder Cones, Spatter Cones and Complex Volcanoes. The Complex Volcanoes are normally 2500m in height and are also called Strato Volcanoes. Shield Volcanoes are high in size and built with many layers. Shield Volcanoes lava is very runny compared to Composite Volcanoes. Cinder Cones normally sit around more viscious volcanoes. Spatter Cones spit out balls of lava. Also they have one vent coming out of the middle of the volcano. All volcanoes could be Complex Volcanoes. They are called Complex Volcanoes because the system is ** __NOT__ ** simple. Complex Volcanoes can join other volcanoes with the same tube going through all if them. Also there can be 5, 6 or even 7 connected. <span style="color: #ff00ff; font-family: 'Comic Sans MS',cursive;"> QUESTIONS <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 120%;">1. What are the atmospheric layers? <span style="font-family: 'Comic Sans MS',cursive;">There are 4 atmospheric layers and they are Troposphere, Stratosphere, Mesosphere and Thermosphere. <span style="color: #0000ff; font-family: 'Comic Sans MS',cursive; font-size: 120%;">2. What effect does the sun and moon have on the Earth? The moon effects the earth in two ways. Its position around the earth allows it to reflect the sun's light into our night. The moon's orbit around the earth lasts about a month giving us different levels of this light. If there was no sun everyone would freeze to death and it would be like -2000 degrees. Also the sun helps plants grow so if there was no sun also plants wouldn't grow.

<span style="background-color: #000080; color: #ffffff; display: block; font-family: 'Arial Black',Gadget,sans-serif; font-size: 150%; text-align: center;">Week 7 <span style="color: #09fb4a; display: block; font-family: 'Comic Sans MS',cursive; font-size: 144%; text-align: center;">Reflection <span style="color: #09fb4a; display: block; font-family: 'Comic Sans MS',cursive; font-size: 120%; text-align: center;">**<span style="color: #000000; font-family: 'Comic Sans MS',cursive; font-size: 108%;">The sun is 4.5 kilometres wide and if we didn't have the sun everyone would freeze to death. Also all of the plants wouldn't grow because the plants move into the direction of were the sun is shining. Also there is actually 5 atmospheric layers and they are Troposphere, Stratosphere, Mesosphere, Thermosphere and the one that i found this week was the Exosphere. <span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">

How can what is in our solar system affect us? ** <span style="font-family: 'Comic Sans MS',cursive;">The Earth formed when all the other planets did. The whole system was once one big disk of gas and dust, with a baby sun in the center. Gradually, the matter coalesced to form the planets. One of them struck the Earth very early on, and the debris from it and the Earth formed a ring, which became the Moon. Comets crashed on the Earth's surface and grazed its atmosphere, dropping all the water we have today, making life itself possible. The Sun drives the chemical reactions here, including those that make life possible. But it can also threaten humans, with solar flares. Another danger from space is an asteroid strike.




 * <span style="background-color: #000080; color: #ffffff; display: block; font-family: 'Arial Black',Gadget,sans-serif; font-size: 200%; text-align: center;">WEEK 8 <span style="color: #09fb4a; display: block; font-family: 'Comic Sans MS',cursive; font-size: 144%; text-align: center;">REFLECTION: [[image:http://www.aerospaceweb.org/question/astronomy/solar-system/solar-system.jpg width="439" height="343" align="right" caption="SOLAR SYSTEM!!!!!! WOW!!!!"]] <span style="color: #00ff00; display: block; font-family: 'Comic Sans MS',cursive; font-size: 90%; text-align: center;">This week I learnt that Mercury is the closest planet to the sun. After Mercury it is Venus, Earth, Mars then the Asteroid Belt. Then there is Jupiter, Saturn, Uranus, Neptune and Pluto. The Moon has 1/6 of the Earths gravity. So if you could throw a cricket ball 100 metres on the Earth, you could throw it 600 metres in the Moon. On Pluto, it is -230 degrees C. Pluto's days go for 6 days and 9 hours and 1 year on pluto is 248 years. All of the planets travel around the sun in a circular motion except for Pluto which moves around the sun in a oval (footy shaped or AFL feild.) **


 * <span style="color: #00ff00; display: block; font-family: 'Comic Sans MS',cursive; font-size: 90%; text-align: center;">The sun is too bright to look through an ordinary telescope. If the sun was a big ball of fire, it would burn out in only a few thousand years. Astronomers say that the sun has been shining for nearly 5000 million years and they think it will shine for another 5000 million years. In the suns core it is 15,000,000 degrees C or more. **

===**<span style="color: #09fb4a; font-family: 'Comic Sans MS',cursive; font-size: 120%;">The face of the sun that we can see is called the Photosphere. The temperature of the Photosphere is 550 degrees C and it is 500km thick. The whole Photosphere moves up and down about 25km every 5 minutes. **===

**<span style="background-color: #ff00ff; color: #09fb4a; font-family: 'Comic Sans MS',cursive; font-size: 150%;">__The Sun__ ** **<span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 130%;">How do humans affect nature? **
 * Well..... we affect nature by all of the car funes and other poisoness gases rising up into the air and striking the ozone layer. When it strikes the ozone layer it makes holes in it which makes it hotter.

<span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 130%;"> How has human use of land caused problems? ** **Erosion is the process of weather and transport of solids like soil, rock and other particles in the natural environment or their source and takes them elsewhere. It usually occurs due to transport by wind, water, or ice.**

<span style="background-color: #000080; color: #ffffff; display: block; font-family: 'Arial Black',Gadget,sans-serif; font-size: 200%; text-align: center;">WEEK 9 <span style="color: #ff00ff; font-family: 'Comic Sans MS',cursive; font-size: 120%;">REFLECTION:

<span style="color: #ff0000; display: block; font-family: 'Comic Sans MS',cursive; font-size: 120%; text-align: center;"> Well.... humans are trying to reduce aor affect on nature by try to walk or ride to school, work etc.
