= __week 2__ =

This week I learnt that you could put music on your wiki page, how to make a voki and that there was a volcanic eruption in iceland.

I want to learn how earthquakes start and if anyone gains anything from natural disasters.

A disaster is something that causes a lot of destruction or devastation.

natural disasters- earthquake, tidal wave, tsunami, bush fire, flood, lightning strike, volcano eruption, drought, tornado.

I think the most dangerous natural disaster is an earthquake because it causes a lot of natural disaster after it. =__week 3__ = This week us grade fives went on camp so there was no __home work!__

=__WEEK4__= This week I learnt that an earth quake is caused by two plates crashing into each other, the earth's structure and that lightning is about 30,000 degrees celcius.

I would like to learn why the sky is blue at day but at night it's black and whether the earth's rotation us slowing down, staying the same or speeding up.


 * Classification of natural disasters:**

The classification of natural disasters depends on the type of disaster. Cyclones and hurricanes are classified by the wind speed, air pressure and storm surge. Earthquakes are measured by the power and the effects on people and buildings.


 * Measurement of disasters**

Cyclones: Measured by category 1 - 5. Depends on wind speed.

Earthquakes: Measured by the Richter scale - depends on power - and the Mercalli scale - depends on effects on people and buildings.

Floods: measured by a scale from Minor to Major - depens on river height and damage to property.

Tsunamis: measured by the height of the wave when it hits the coast.
