=week 2 = **reflection** **1. ****The closer you are to the equator the further you will be from the two polar regions. ** danger includes: **
 * 2. ****At the equator you are closer to the sun and have a hotter climate. **
 * 3. ****At the poles you are further away from the sun and you have a colder climate. **
 * 4. ****Nature can put us in danger but also keep us safe. Some examples of putting people in

**4. i also found out that their has been 2 volcano eruptions in iceland. 5.I herd that when we had the big earthquake in chilli it acually moved the angle of the earths tilt.**
=**focus questions**= =<span style="color: #800080; font-family: 'Courier New',Courier,monospace; font-size: 110%;">What do we use to classify disasters? = ===there are scales based on our observation of there impact or objective measures such as wind speed or the strength of an earth treamer.=== =<span style="color: #800080; font-family: 'Courier New',Courier,monospace; font-size: 120%;">How are they measured? = ===These days i think we use a fractal.A fractal is a mathematical formula of a pattern that repeats over a wide range of size and time scales. also the amount of force.=== **storms,tornadoes,hurricanes-** T he beaufort scale,the beauford scale is a set of discriptions with a scale number( Calm=0 at < 1km/h, fresh breeze=5 at 29-38km/h ,strong gale=9 at 75-88km/h ,hurricane force=12 at __>__ 118km/h). These match wind speeds. =<span style="background-color: #00ffff; color: #ffffff; display: block; font-family: 'Courier New',Courier,monospace; font-size: 160%; text-align: center;">week 5 reflection! = =<span style="color: #9700ff; font-family: 'Comic Sans MS',cursive; font-size: 110%;">**What are the layers of the earths structure?** = <span style="background-color: #1c1717; color: #00ffff; display: block; font-size: 130%; text-align: center;">reflection 1. A circle or round is the strongest shape because it has no weak points. 2. Jupiter is the biggest planet. 3.Venus is supposed to be the most beautiful planet of them all but it really isn't. 4.Venus is covered with volcanoes. 5. Mars is on the left of the asteroid belt and Jupiter is on the right. 6.Humans have a tail bone. 7.The order of the planets is Mercury,Venus,Earth,Mars,Asteroid belt,Jupiter,Saturn,Neptune,Uranus and Pluto. 8. Ages ago in the middle of Australia there used to be a inland sea. =<span style="background-color: #00ffff; color: #ffffff; display: block; font-family: 'Courier New',Courier,monospace; font-size: 160%; text-align: center;">week 6 =
 * earthquakes-** Richter scale, the bigger the earthquake the bigger the number will be.
 * bush fire-** The size of the fire,the heat intensity.
 * floods-** You would measure it by the depth and the water flow speed.

What are the different atmospheric layers above us **?**
We have a troposphere which is were we are 10 km high,stratosphere 10km-50km high,meospher 50km-85km high,thermosphere 85km-500km high,exosphere 500km-520km high. ==<span style="color: #9700ff; font-family: 'Comic Sans MS',cursive;">What effect does the sun and moon have on the Earth? == == Because of the tilt of the earth, not every place on earth gets light every day. Also, some places have extremely short days. As the earth around the sun, the place where light shines the brightest changes. This motion gives us the different seasons. For instance, the poles receive less light than does the equator because of the angle that the land around the poles receive the sun’s light. When the north pole is tilted toward the sun, the northern hemisphere is presented to the sun at a greater angle than the southern hemisphere and the northern hemisphere gets warmer. When this happens, the northern hemisphere gets summer while the southern hemisphere gets winter. When the south pole is tilted toward the sun, the two seasons reverse hemispheres. This is illustrated in the following image. ==

Energy received during the day keeps the Earth from freezing and gives plants the energy for photo synthesis. The Sun's energy warms the oceans and the air to produces all forms of weather from Arctic blizzards to tropical monsoons, typhoons, tornadoes and hurricanes. The Northern Lights are the result of the Sun's energy being brought down to Earth by Earth's magnetic field. The Sun's gravity keeps the Earth in orbit as well as creating Solar Tides in the oceans. The Moon also produces tides. The Moon also helps protect the Earth from bombardment by some meteors. The Moon has thousands of craters from meteors which might have hit the Earth if not for the Moon. The other members of the Solar System provide us with interesting things to see at night, including comets, planets and meteors which we call falling stars. =<span style="background-color: #000000; color: #00ffff; display: block; font-family: 'Courier New',Courier,monospace; text-align: center;">Reflection! =

 * 1) Earth travels in space on a path or orbit around a star we call the sun.
 * 2) The solar system is is about a million times wider than earth.
 * 3) 'solar' means 'of the sun' and the sun is by far the the most importent of the family.
 * 4) It is about 740 times more massive that all the planets put together.
 * 5) Because of its great size, it has a powerful gravatational pull,and this pull keeps the solar system together and controls the movments of the planets.
 * 6) The solar system began about 4.6 billions of years ago.
 * 7) The'empty'space between stars in in fact contains hydrogen atoms and tiny grains of solid matirial.
 * 8) The grains lie very far apart from each other.
 * 9) How ever, in some regions of the galaxy the grains are found much closer together,forming dark clouds of gas and dust.
 * 10) These regions are called nebulane.
 * 1) If you can take several layers of paper, hold them by the edges and then push, they will bend into a dome.
 * 2) When theyare pushed or pulled, they may recover if the pressure is remved quickly.
 * 3) If the rock is brittle and deformed too much, it will break.
 * 4) The rock will bend if it is more elastic.
 * 5) If you hit a rock hard enough with a hammer, it will break.
 * 6) It is hard to imagine a rock bending than breaking.
 * 7) A break in the rocks are known as a fault.
