= __//**Week one**//__ =
 * This week i learned**

you cant jump through a tsunami before it breaks.
= **week two** =
 * I would like to know how gravity works?**

**how a earthquake works?**

 * What is a disaster?** A disaster is when something bad happens and you can't control it to stop it.


 * What are the different disasters?** There is tidal wave,hurricane,earthquake,bush fire,comet,flood,drought,storm and dust storm.


 * What is the most da****ngerous disaster?** I think the worst is a earthquake because it destroys everything and causes fires. Not including asteroid's.

= __//**Week three**//__ = No homework the grade fives are on camp.

The worst natural disaster would be an asteroid because it could destroy earth if it was big enough.

=__//** Week four **//__= This week i learned what we use to measure disasters and what there based on. As well as earthquakes cause a lot of other natural disasters like a volcanic eruption,tsunami and fires. I also learned about the plates when they hit it makes an earthquake. The cores center is hotter than the suns surface and all lava comes from the center of the earth.

its more accurate. The Mercalli scale is only based on destruction but the Richter scale is based on how big the tremor it.
 * What​ do we use to measure disasters?** We used to use the Mercalli scale but now we use the Richter scale because

= __//**Week five**//__ = This week i learned about the gravity it pull's stuff down including mountains but we can move because we have muscles. I also learned about the solar system having Rock planets and Gas planets as well as the sun and the asteroid belt. The asteroid belt is all the asteroids that didn't get sucked into a planet. As well i learned about the Earth's structure.


 * What is the Earth's structure?** The Earth's structure. The first layer is the earth's crust is from 30 km to 50 km deep and is 375 degree's hot. Then there's the Mantle is 2800 km deep and can reach a temperature of 3500 degree's. Then there's the outer core it is made of liquid. Now the inner core it can get to a temperature of 4500 degree's.


 * What resources do we use from beneath the Earth?** We use gold,coal,iron,steel,silver,special stones,some rock's and petrol.

= = = __//**Week six**//__ = This week i learned about volcano's. There is the Composite volcano 1000 m wide and 2500 m high and has a viscous eruption. The Shield volcano which is wide and short and the lava is fast. The cinder volcano is weak and only shoots out cinder and ash.The Spatter volcano shoots out balls of lava.

**What are the atmospheric layers?**


 * What effect does the sun and moon have on the earth?** If there was no moon it would be hot and sunny all the time because the moon blocks the sun at night and we would die because it would be to hot and its the same with no sun but dark and cold.

= = Week seve n __//** a little bit about the atmosphere. The first layer of the atmosphere is the troposphere thats where all the wheather happens the second layer the stratosphere is where planes fly because its very stable the third layer is the mesophere thats where all the meteors get burnt and stop the fourth layer the thermosphere is where space shuttles go and satallites.
 * //__

The moon blocks the sun for night and The sun blocks out the moon for the day. meteors can also hit earth which could kill us all.
 * How can what is in our solar system affect us?**

If an asteroid were to hit earth it could destroy countries and maybe kill or the creatures on Earth including humans.
 * How can comets, meteors and asteroids affect us?**

= __//**Week eight**//__ =

This week i learned about the planets and what order there in. Mercury, Venus, Earth and Mars are the rock planets and Jupiter, Saturn,Uranus, Neptune and Pluto are the gas planets. All planets circle around the Sun except Pluto which goes around the Sun in a oval. Mercury is light brown Venus is pink Earth is green and blue mars is red. Jupiter rainbow from the gases Saturn is blue Uranus is dark blue Neptune is blue and Pluto is yellow and brown.

Humans go to forests and chop the trees down to build homes and kill animals.
 * How do humans effect nature?**

Well we normally mkes homes near forets whick kills the animals and destroys trees so we have less air.
 * How has humans use of lands caused problems?**

I think we are because we go around killing everything and using everything up like resurces.Take the oil spill for exsample its killing marine wildlife and destroying the gulf of Mexico.
 * Are we more dangerous to the Earth than natural disasters?**

= Week nine = This​ week i learned that humans can cause natural disasaters like avalanches landslideas and more. Neptune has winds so stron your skin would come off and Pluto could be a moon off Neptune.

Where trying to make new stuff like electric cars.**
 * How are humans reducing the affect to nature?
