Natural Disasters - Padlet Brainstorm by Steve https://padlet.com/sfr1/fjys9220og65 en-us 2016-07-24 09:08:48 UTC 2024-03-06 19:28:09 UTC hello@padlet.com Tanya https://padlet.com/sfr1/fjys9220og65/wish/117273593 Tsunamis can be formed by tectonic plates in the sea pushing against each other and one finally gives way it causes a massive ripple sending waves crashing onto shore. Another way a tsunami is formed is by a volcano . An underwater volcano erupting can be the cause of a tsunami as well. Also, the tsunami can be formed by an earthquake. Earthquakes are caused by tectonic plates on land pushing against each other. Volcanic eruption is caused by magma from beneath the earth's crust from the mantle,  by pressure, pushing up in craters. Bush fires can be man made. A bush fire can be caused by an out of control fire. This is why controlled fires are important. Also, when lightning hits the earth, it causes fire and that can lead to a destructive bush fire. Droughts are when the el nino weather pattern occurred.

I believe earthquakes are the most destructive natural disaster as millions of people can die or be wounded and buildings can collapsed. Also, natural disasters can be formed from earthquakes such as tsunamis. This is a very destructive disaster and has a large amount of impact on land an the people. Most of the natural disasters occur in the part of the earth, it is known as the ring of fire and it is surrounds the pacific ocean. Hundreds of volcanoes, earthquakes, hurricanes, tsunamis and many more are held in the ring of fire. When a volcano erupts, the gases are poisonous so you can't breathe in either.

Earthquakes form mostly on lands that are located right on the edges of the faults, such as Japan; who have approximately 100 earthquakes per day.

I also believe this is the most dangerous natural disaster because of the impact it has. It destroys the earth and the buildings around it forcing the earth to shake violently, preventing humans and animals from moving (because of the shaking it is difficult to move.) If you think that is bad, most earthquakes also create floods, the stronger the earthquake the larger and further the tsunami. Earthquakes can also cause volcanoes to form.

From the fact that earthquakes not only do extreme damage but they cause 2 other disasters that are just as dangerous concludes that earthquakes are the most dangerous natural disasters.]]> 2016-08-01 03:34:53 UTC https://padlet.com/sfr1/fjys9220og65/wish/117273599 Scott https://padlet.com/sfr1/fjys9220og65/wish/117273603 Destroy thousands of homes

Tectonic plates can be pushing against each other for hundreds or either thousands of years. When on tectonic plate is pushing harder that tectonic plate will slide on top of the other tectonic plate, this causes a tsunami. When the plates are pushing against each other, they create a lot of electricity, so when one tectonic plate slides on top of the other tectonic plate, all of the electricity gets released so it gives the wave a lot of power. When at sea the wave is about three foot tall (90cm). When the tsunami hits the shore, the wave stretches up to a height that can be 100 feet (30m). This is because of the released electricity. Like ripples, there are a lot of other waves. The largest wave would be at the front followed by lots of other waves getting smaller and smaller. The largest wave would be the slowest, and the other smaller waves would be faster, so therefore the waves would increase in size for a larger impact.

For this reason, I would consider the tsunami being the worst natural disaster.

A meteor shower is when a meteor brakes the ozone layer and is so hot that it shatters and sprays everywhere in many directions depending how fast it is. A flaming twister is probably the most dangerous out of the natural disasters because of the fact it is a literal line of spinning fire that disintegrates nearly everything in its path it is just like a tornado but it is upside down and is super heated like an oven burning at 300 degrees Celsius (approx) all of these happen rarely not as much as the normal tornado but these are some of the most dangerous natural disasters. the ring of fire starts in new Zealand and travels to the east coast of Asia

- floods
floods can damage buildings and can cause harsh car accidents and can kill and injure many people in that area...
- volcano eruption
volcanic eruptions can be very dangerous to be near because they produce ashes which can harm people such as in the city Pompeii, Italy there volcano erupted and the ashes sent people to get stuck under concrete and now the people have been covered by concrete and in this volcanic eruption over 2million people died. volcanoes also produce very hot lava which can kill or highly burn or injure people...
- bush fire
sometimes bush fires can be caused by accidents or on purpose such as back burning but most of the time bush fires can kill many trees and parklands near bushes plus the bush itself and since in a bush there is non stop trees so there is a lot in one area so when one tree burns the rest burn.
- drought
droughts are dry seasons for long periods of time which cause humid, warmth weather and people can lose fresh water which can cause sever dry mouth and dehydration if not drinking enough.

Tsunamis are the most dangerous natural disasters.

Volcanoes blow out giant explosions because of gas built up inside the rock, the fumes of the gases are poisonous.

Homes cannot be built in certain areas

Droughts formed by la nina can harm all life in a certain area and last for ages.

Earth quakes are formed by rubbing of the ground on tectonic plates. They destroy whole cities and families get separated, they also get infectious diseases such as epidemics.

Cyclones are formed by the mixing cold water temperatures with the hot air temperatures being spun by the world.

A flood is when the weather is very rainy and things overflow which makes water levels rise massively.

A drought is when the weather doesn't rain as much as it should and there is a lack of rain which makes the earth very dry and as a matter of fact, animals die and grass dies.

They are all natural events. 
====
Earthquakes are formed when two tectonic plates being force together by other tectonic plates and collide with each other. When that happens, pressure builds but sometimes it takes up to thousands of years for the pressure to build enough for an earthquake to occur. When the tectonic plates have enough pressure, one may spring upwards and make the crust above the earthquake shake. Some earthquakes who may not feel and some earthquake are deadly and violent and are easily felt. 
====
IF an earthquake happens where the crust is under water, it may form a "Tsunami" if it is powerful enough. The tsunami is a series of tidal waves that get forced across the ocean until it hits land. When the tsunami is formed by an earthquake, it would look like a ripple when you drop a drop of water into a cup of water. The tsunami acts like that but much larger. When the tsunami is in deep waters, it doesn't look like much. It might be about 3 metres high. When shallow water comes, the water is forced so much that the water keeps it's shape in the deep water and causes the wave to rise up to 30 metres.
====
Tornado are formed by serve thunderstorms. It happens when wind comes at opposite directions of each other and forms a wall cloud which 2 out of 3 times forms a tornado. Tornadoes can form from a F0   (weakest) to a F5 (strongest). Most tornadoes form in "Tornado Alley" in USA. Tornadoes to damage to homes and crops and when in F2 or higher, it may injure or even kill people if they don't get warnings. 
====
Droughts happen when hot weather comes along and no rain happens which dries out the land. This usually occurs in the outback but may occur near coast. 
====
Volcanoes are usually formed on/near tectonic plates.]]> 2016-08-01 03:37:27 UTC https://padlet.com/sfr1/fjys9220og65/wish/117273770 ETHAN https://padlet.com/sfr1/fjys9220og65/wish/117273779 Earthquakes happen when two tectonic plates collide against each other then eventually one will slip and then  the land will shake causing an earthquake.

Earthquakes can be made by two tectonic plates having an uneven amount of force eventually making a plate go up starting an earthquake. Avalanches can be created by too much snow on an area and the different layers of snow are not sticking together. Volcano's ash can suffocate and if there are air bubbles in the lava, it cannot stand the pressure anymore and will explode sending hot air that acts like an avalanche destroying everything in it's path. ]]> 2016-08-01 03:37:34 UTC https://padlet.com/sfr1/fjys9220og65/wish/117273780 DJ https://padlet.com/sfr1/fjys9220og65/wish/117273785
  • Magma rises through cracks or weaknesses in the Earth's crust.
  • Pressure builds up inside the Earth.
  • When this pressure is released, eg as a result of plate movement, magma explodes to the surface causing a volcanic eruption.
  • The lava from the eruption cools to form new crust.
  • Over time, after several eruptions, the rock builds up and a volcano forms.

    1. Earthquakes are usually caused when rock underground rocks breaks along a crack. The sudden release of energy causes the seismic waves that make the ground shake. When two bits of rock or two tectonic plates are rubbing against each other, they get a tiny bit stuck.

    -A drought is caused by lack of rain which causes less water for the soil, plants, rivers for animals to drink from, and sometimes people. This causes the land to change and the animals not being able to live properly which puts an impact on their health in being able to have their young. This puts an impact on people out near charleville as an example because they can't get the meat, milk e.c.t that they need 
    -The least harmful disaster is probably the drought, even though there isn't much water, people can dig through the soil to find the moist soil from deep underground from where the plants get the water from
    -The deadliest disaster is probably a tsunami because there is no way to stop it and it puts an enormous impact on the land demolishing buildings, plants/animals, houses, aquatic areas, the soil would be soaked and is not dry enough to stop a flood

    Tsunamis are formed when the tectonic plates slide along each other and formed an undersea mini earthquake that creates a 1 metre high wave that moves at terrifying speeds till it reaches the start of the incline as the beach is formed where they can reach 50 metres at times.

    Cyclones look like an eye made of earth.
    Tsunamis are formed by heaps of tech tonic plates that smack against each other to create massive, tall waves that crash over a city. Droughts are caused by a large area that hasn't had quite a lot of rain for a long period of time. For example: the QLD outback has been in drought for 9 straight years. I think that the worst natural disasters are bushfires. I think this because they can destroy anything that is caught up in or near the fire. Volcanoes are another bad one because they can just all of a sudden blow up or erupt unexpectedly and kill many, many people and creatures of the world. It can also destroy houses and buildings

    6. Volcanic Eruption

    Some of these natural disasters including earthquakes, tsunamis and volcanic eruptions are caused by the tectonic plates moving underneath the Earth's surface. A natural disaster is a catastrophic event that occurs by the forces of nature.

    Tornadoes -
     are formed by harsh wind and superheating making it go up. 

    Tsunamis -Tsunamis are caused by the tectonic plates causing an earthquake. The earthquake must be in the water for a tsunami to occur. The earthquake acts as a rippling effect that creates many normal sized waves. As the wave hits the shore bank it goes up the other waves that were following behind clash with the first wave which creates an extremely large wave.

    Avalanches - Avalanches are formed by massive chunks of snow breaking of a mountain then on the way down collecting more and more, than its dangerous. 

    Volcanic Eruptions - Volcanoes are formed by magma coming through and causing the lava to burst through plates with degrees way beyond mankind can last. Also volcanoes can make new land and structures on earth. Volcanoes can make new islands, magma comes up through the ocean and pushes against the crack separating the two parts. 

    Earthquakes - Earthquakes happen when two tectonic plates collide against each other then eventually one will slip and then the land will shake causing an earthquake. The sudden release of energy causes the seismic waves that make the ground shake. When two bits of rock or two tectonic plates are rubbing against each other, they get a tiny bit stuck. If an earthquakes is strong enough it will tear buildings apart causing them to stumble down violently possibly killing innocent children, men and women which kills thousands of people
