 * this week homework is
 * what is a disaster
 * a disaster is a natural catastrophe that causes great damage or life loss.


 * different type of natural disasters are
 * a earthquake
 * a Tsunami
 * a Tornado
 * cyclone
 * sinkhole
 * Typhoon
 * Volcano
 * storms
 * cyclones
 * floods
 * bushfire
 * avalanche
 * blizzard
 * hurricane
 * whirlpool
 * land slide
 * sand storm

I believe that earthquake are the most dangerous because they can kill heaps of people. E.G like when a building falls down and heaps of people are in it and they die.

my refletion this week is that i learnt much more on sinkhole and what a typhoon is and a land slide.

800 people that lived near the iceland volcano were evacuted. in1980 there was a volcano that let out 1,500,000 metric tones of sulfur dioxide into the atmosphere, or the catastrophe of Krakatoa in Indonesia in 1883, which

how do you classify natural disasters earthquake ricterscale volcano



week 5 homework

the layers of the earth
 * 1) 0- 40k Crust
 * 2) 40- 400 k Upper mantle
 * 3) 400- 650k Transition region
 * 4) 650-2700k Lower mantle
 * 5) 2700-2890k D'' layer
 * 6) 2890-5150k Outer core
 * 7) 5150-6378k Inner core

Fossil fuels, coal, oil and natural gas, are a non-renewable source of energy. Thats what resources are under the earth.

week 5 reflection. i learnt what the layers of the earth are and what is under us and what fossil are used. \

week 6

what are the different atmosphere layers themosphere mesosphere stratsosphere troposphere

__the moon__** The moon has a noticeable effect on the earth in the form of tides, but it also affects the motion and orbit of the earth. The moon does not orbit the center of the earth, rather, they both revolve around the center of their masses called the barycenter.
 * What effect does the sun and moon have on the Earth

Because of the elliptical nature of the earth’s orbit and constant changes in the earth’s rate of spin because of the previously mentioned phenomena, the sun, as seen from earth, is moving at a non-uniform rate. This makes it difficult to use the real position of the sun as a reference for time keeping. For these purposes, a point which moves at a constant rate around the earth is used instead of the real position of the sun. This point is called the mean sun and is the basis for mean solar time.
 * __the sun__**

Question what would happen if the sun got to hot and blow up. Answer A star with a mass similar to that of our Sun and in the last phase of its life is a red giant. At this point, the Sun will have expanded to cover all the interior planets, including the earth

Question How big is the moon? Answer The Moon, with 3,456 km in diameter, is more than one quarter the size of Earth.



week 7 the plantes are about 4.3 billon years old
 * Since the Sun is by far the largest supplier of energy to the Earth's surface, any change in the radiative output of the Sun also affects the energy balance of the Earth's surface.
 * Also, changes in the solar spectrum, in particular in the UV, could enhance this influence by affecting stratospheric chemistry: most importantly the balance between ozone production and destruction. Although the UV radiation shortward of 400 nm contributes only about 8% to the magnitude of the total solar irradiance, it is responsible for about 60% of the variation of the total irradiance.
 * Finally, the Sun may influence the Earth's climate also in other, more convoluted ways, e.g. by modulating the flux of cosmic rays, which have been proposed to increase the coverage by low-lying clouds.
 * But how strong the Sun's influence is and which mechanism is playing the main role is a matter of current research. The Sun's influence on the Earth's climate can not be measured directly. However, good correlations have been found between different proxies of solar activity and climate records, for example, between the concentration of 14C in tree rings and glacier fluctuations (Fig.1).

reflection week 7 the sun is 4.3 billion years old. I learnt how do do a lot experimants like land slide, earthquake (exc) and what CSIRO means

week 8 the humans are the ones that are blamed for global warming global warming is likely to change we have 20 years of warming the sea level will rise by 28 to 43 centermeaters in global warming change

reflection week 8 I learnt that cyclone Kartreana is a cyclone.
