I even came up with my own dictionary meaning for disaster and this was mine... DISASTER: something extremely bad that occurs not very often.
 * week 1: **

**Questions:** what causes a volcano to errupt? how does a tsunami start? why do natural disaster occur in some countries more than others?

i think the most dangerous natural disaster is a tsunami and volcano because...
 * week 2: **

TSUNAMI: Thousands of people can lose their lives. the problem with a Tsunami is nobody can predict when and where it happens. Even a strong earth quake under the sea is not predicting how much power the wave has, when the Tsunami travels thousands of kilometers on the ocean surface to an island or continent.

VOLCANO: a volcano can kill many people or very seriously burn them or there houses also because lava is the hottest liquid in the world. the most dangerous part of a volcano is the Pyroclastic cloud which is made of lots of dangerous volcanic gasses and ash.

**week 3:** i was at camp! SO FUN.

This week i have learned about the tectonic plates that lay beneath the earths crust, i have also learned that the inner core is hotter than the the suns surface. Another thing i have learned is an earthquake is made when the tectonic plates smash together. One more thing that i have learned is how to measure earthquakes, there are two ways- richterscale which measures damage and the mercalli which measures how bad it was.
 * week 5: **

this week i have learned about the people in pompeii and how the hot ashes sufficated the people to their death by covering them in 3 metres of ash untill there was no possible way to get out from under it.
 * week 6: **

this week we had a person from CSIRO come in and talk to us about natural disasters i learned that the most dangerous volcano was pumis which takes 20 millisecond to travel down a volcano. The next one was obsidian which takes about 20-30 seconds.
