let me share some interesting facts for now since I have nothing much to do now and am rather free..this post might get rather boring cos it is gonna be a long long post..haha!think it's better that people who cant read long entries to not read cos it's very long...hahaha!might make you sleep too...hurrr=DDDD
just some fun facts..
let's talk about volcanice eruptions then..haha=PP
the documentary influenced me to want to know more about the volcanic eruptions...
VOLCANOES
What is a Volcano?
It is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. Gases and rock shoot up through the opening and spill over ot fill the air with larva fragments. Eruptions can cause lateral blasts, lava flows, hot ash flows, mudslides, avalanches, falling ash and floods. An erupting volcano can trigger tsunamis, flashfloods, earthquakes, mudflows and rockfalls.
Why do Volcanoes occur?
Deep within the Earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Because it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually some of the magma pushes through vents and fissures in the Earth's surface- a volcanic eruption. Magma that has erupted is called lava.
How do volcanoes form?
Deep inside Earth, between the molten iron core and the thin crust at the surface, there is a mantle, a large layer of rock that is largely solid, but flows like plastic. When rock from the mantle melts, it sometimes moves to the Earth’s surface through weak spots in the crust, releasing heat, gasses, and rock--a volcanic eruption. But why does this solid(pyrolitic) rocks melt and come to the surface. Due to the temperature, pressure and the presence of the water, which facilitate the rocks' melting.
As one goes deeper and deeper into the earth, there is increasing temperature with increasing depth. This is because radioactive elements deep within the earth are slowly disintegrating and producing heat. The rock in the earth insulates the heat, so that it accumulates and eventually liquefies the rock insulating it. Only slowly does this heat escape, which leads to the drastic differences of temperature with depth. This difference is referred to as the geothermal gradient. The average geothermal gradient is 2° to 3°C per 100 meters of depth, indicating that heat is flowing outward from inside the earth.
Volcanoes are vents for the explosive escape of some of this heat. Magma is a term referring to a mass of completely or partly molten rock containing the volatile that it acquired at its origin in the upper mantle of the earth. These volatile elements are gases either dissolved in the melt or as bubbles of gas that escape when the rock reaches the surface and solidifies. Volcanoes erupt because magma is less dense than the solid rocks surrounding it in the mantle of the earth. As it nears the surface, the volatile gases expand and boil out of the rock, and this force of explosion propels lava from the vent.
Why do volcanoes erupt in different ways?
Most volcanoes occur on plate boundaries. Plate boundaries are areas where Earth's shifting plates meet or split apart, usually with violent results.
Plate margins that are coming together are called convergent margins, while those that are splitting apart are called divergent. A third type, transform-fault margins, are sliding against each other, going in opposite directions (like those of the San Andreas Fault). Volcanoes can occur on convergent or divergent plate margins or over a hotspot, a spot inside the mantle that heats an area of the plate above it.
Colliding Plates
Along convergent margins, when two plates meet, sometimes one descends, usually of oceanic composition, beneath the other, usually of continental composition, in a process called subduction. As the descending plate is forced deeper into the mantle, parts of it begin to melt and form magma that rises to the surface, often in explosive eruptions. Subduction zones tend to create large, classic, cone-shaped volcanoes called stratovolcanoes, such as Mt. St. Helens in Washington State, or Mt. Shasta in California.
Separating Plates
At divergent margins, plates are coming apart and hot rock forces its way to the surface. Many divergent plate margins are under the oceans, creating long undersea rift zones that fill with lava. In some eruptions at divergent margins, the relatively calm, smooth flow of lava creates volcanoes with gently sloping sides, called shield volcanoes.
Hotspots
Hotspots can also cause shield volcanoes to form. As plates move over hotspots, volcanoes spring up and die down in turn, often creating an island chain. The Hawaiian Islands are the result of a hotspot.
Effects of Volcanic Eruptions
It also causes various kinds of hazards like lava flows, pyroclastic fall depositsm volcanic gases, tsunamis and more but lava flows has been known to have killed small number of people due to the prediction of the volcanic eruption that enaled an evacuation of the people. The majority of damage that were brought about by the volcanic eruption were economic, agricultural and runing the settlements.
There are five gases that are produced by volcanic activity. All of these gases are harmful except for water vapor. These five gases are water vapor, carbon dioxide, sulfur dioxide, fluorine, and chlorine.
Carbon dioxide is one of the main causes of the Greenhouse effect, but there are not significant amounts for the carbon dioxide emitted from volcanic eruptions to contribute to the Greenhouse effect
Sulfur dioxide can have a short-term effect on the weather. A sulfuric acid aerosol can remain in the atmosphere for years after an eruption (Fisher). This aerosol blocks the sun and causes cooler temperatures globally. The sulfur dioxide eventually depletes, but is replenished by each eruption rich in sulfur dioxide.
Fluorine can be a deadly to animals after an eruption. It tends to condense in rain and coat grasses and plants (Fisher). The fluorine is poisonous to animals that eat the fluorine-coated grass and plants.
Chlorine is emitted as hydrochloric acid into the atmosphere. Chlorine destroys the ozone layer that protects the DNA of plants and animals (Fisher).
Water vapor is the only one of these gases that helps society by replenishing the water supply.
The volcano eruptions may seem to cause much damage to the society but there are positive effects too. the negative impacts of the volcanic eruption would seem to have over-powered the positive impacts but there are still positive impacts of the volcanic eruption. It provides with an enriched soil and help in creating earth's early atmospheres and minerals.
Types of Volcanic Eruptions
Plinian Eruptions ( Most powerful eruption)
Strombolian-type eruption 
"Vulcanian"-type eruption
"Vesuvian" eruption
"Hawaiian" eruptions 
"Phreatic" (or steam-blast) eruptions
think i shall stop this entry already..hahaha!its like so long already..maybe I continue in the next entry or wad ar....
taaaas

hey tooties...
for a moment I thought that I could sleep in a bit more when I planned to not go school and give myself a short break since there wont be any test or training on this day..guess what, I was like awoken by my brother when he entered the room and asked me to go breakfast with him..i was like.."huh, breakfast?"was just so lazy to move in the aching muscles from the training yesterday and played some basketball after the training..was quite fun to play basketball after like so long since I last played basketball but it was quite funny instead..haha!just can't stop laughing the whole match la..the people were seriously damn hilarious..
anyways, think he has a good technique to wake me up..just by claiming that someone from his school lost his life, just woke me up instantly, even from a state of zombie to a dunno what state..haha!he then just brought in the laptop and asked me to play with him but being the lazy ass for that moment, just refused and lazed in bed..end up, he played alone but beside me, keeping me awake and only managed to catch like another 10mins of rest and then I woke up alr..
hmmm..dunno what's up for today though..
wonder where I should go later...

hippee-hippowednesday was finally a day where I can get up slightly later than usual but still I need to be in school like as early as 11am just for the sake of lab. guess what we did in the lab session was totally a waste of time la..seriously!look at what we did..prepared ngm plates, then decided to try the fluorescence assay to determine the oxidative stress and so we discussed and calculated the protocol and proceeded on to pick like 30 worms each?omg!tell you, the eyes can really go berserk man!after picking, we all decided to take a break, went for lunch break in a team and talked abit before heading back to lab to try out the assay but guess wad, tried and tried, still not results and lab ended at like 4.45 when I was required to go home and get my stuff for training!!omg!walked out of the school to the interchange with the advisor and for the first time, I went home with the advisor cos it happened that she was going westmall.talked to her about almost everything, she asked about floorball, about after-poly life..quite interesting though..den after that, rushed home and pack my stuff before my dad sent me to sch..otherwise i'll b like dunno how late la..
friendly after that..
training first before the friendly and guess the friendly was great!all of us played well as a team and still stayed strong till the very end.. I really like that kind of attitude!=DD the fight we put for every ball and the effort that we all put in..all was just so commendable!=DDfriendly ended with a draw..both teams were just as tough as the rock la..we are all just strong in our own ways.
after that rushed off to shower and all..first time I showered so fast after training cos I will just end up being the last everytime..hmmm..
packed and got ready to leave and nina and friends were down to watch..(sounds so like barney & friends)hahahahaha!!!=PPP
didn't join the normal people for dinner but instead left with the others..talked to reena on the way to the interchange and at least it got me a bit better but still left me quite affected somehow..hmmm..
from there, was hungry and so I decided to want to eat but the rest left and so headed for dinner at macs before going home.. reached home late but just couldn't slp..hmmm..
sch today was alright..with not many people and all, we changed the lesson into a game session because it wont be tested in the test and so to make it more interesting and to make everyone involved and participating...
class ended and left to meet the rest in the lib..
omg!just can't believe I really really fell asleep in the lib just for that 15 mins?
after that was awoken suddenly by dunno what but yeah..got me slightly refreshed up at least before the training..
training was seriously madness..
great I managed to pull through the whole training despite the tiredness..
now I'm like aching like badly..
maybe no sch tmr ?rest day..weeee
hahahaha!long weekends ahead loooo!!!=PPP
(banana,will pass you the choco like soon and thanks for the encouragement..hahaha!=Dwas glad you came)(miss sya, thanks for the words of encouragement too!!you were like so powerful lah..don't worry, you were great!)guess that's just all..
