3rd term

This is the last term and in this term we are going to do a project about climate change to participate in a competition. I think that it is a good idea to learn about it because we need to do a lot of things very interesting; like, an advertisement, the song... It will be very nice.

stop war

STOP WARS

Nowadays, the world is becoming a place full of war. It is getting worse. We need to change this but I think that it is impossible now. All the people have different point of view and some think that to have war it is going to be better and others think that it doesn't work. In my opinion for example, I don't think that it works it put the things more complicated. A lot of people die because of that and we need to stop that.  

The responsible of the war are the rich countries. The poor countries suffered from rich countries attacks. They waste millions for the army things. I think that it is too much money to waste on that. However, I think that we couldn't live without war, I can't imagine it. There is nothing to do against that.

Hungarian nationalist TV camera operator filmed kicking refugee children

The Hungarian camera operator who was filmed kicking two refugee children and tripping up a man at the border hotspot of Röszke this week has apologised, saying “something snapped in me” and she cannot believe her actions.

In a letter to the rightwing daily newspaper Magyar Nemzet, Petra László said she had been in a state of shock since the incident on Tuesday, but denied accusations of racism.

“The camera was shooting, hundreds of migrants broke through the police cordon, one of them rushed to me and I was scared,” she wrote.

“Then something snapped in me … I just thought that I was attacked and I have to protect myself. It’s hard to make good decisions at a time when people are in a panic.”

László added that she was willing to take responsibility for her actions, but went on: “I’m not a heartless, racist, children-kicking camerawoman. I do not deserve the political witch-hunts against me, nor the smears or the death threats.

“I’m just an unemployed mother of small children, who made a bad decision. I am truly sorry.”

László was fired by Hungarian nationalist television channel N1TV after video of the incident was posted on Twitter by Stephan Richter, a reporter for the German television channel RTL.

N1TV – which has links to the far-right Jobbik party – said her behaviour was “unacceptable” and her job had been terminated “with immediate effect”.
On Thursday, Hungarian prosecutors said a criminal case for breach of the peace had been opened against her. Sandor Toro, the deputy chief prosecutor of Csongrád county, said: “In the course of the investigation, the authorities will also examine if more serious crimes … can be established.”

The incident happened on Tuesday as hundreds of people broke through a police line at Röszke, a collection point close to the Hungarian-Serbian border where thousands of migrants have been crossing every day for the last month.

fat but fit

   FAT BUT FIT

Scientists believed that excess body fat was mere storage for unused calories. However, research conducted over the past 20 years suggests added fat is more than a little extra cushion.

In 1998, the National Institutes of Health (NIH) published a guidelines and in it said that if you are overweight but good physically you will not die earlier.

But in 2015  the International Journal of Epidemiology did a study and said that what NIH said about "fat but fit" wasn’t true. Compared to physically fit obese men, normal-weight men who were not physically fit had a lower risk of dying.

Abdominal obesity, which is fat centralized in the belly, is a sign of high levels of visceral fat in the body. Visceral fat is the type of fat that accumulates in arteries and around organs, and has been credited with increased inflammation and disease risk.  

Another study saidd that it is a myth. It said that

If you are overweight, a study suggests that even doing lots of exercise will not prevent an early death. Researchers say it is far more important to be slim, even if you are unfit. For years experts have believed it is possible to be ‘fat but fit’ and still relatively healthy. This led to some heavier adults assuming a few extra kilos did not matter as long as they took regular exercise.

In conclusion, exercise does a body good, but new research suggests it does less good for obese bodies. Swedish scientists launched a massive study to try and find out whether being highly fit can mitigate the risk of early death that comes with obesity.

2ND TERM

We have finished the first term of scientific culture. Now we will start the second term. In my opinion the second term will be more interesting because I like more the biomedicine theme. I think that in the future I will do something related with  medicine.

continental drift

                     
                                                   CONTINENTAL DRIFT


Until 1912 people used to think that god created the Earth and that the 5 continents and the 5 oceans have been always there.

Wegener was a german meteorologist. He said that all the continents were in the same mass of continent, he called it pangea. But by the time they saw that the continents were sepearing from each other.

The reason was in the underground. There was a mantle that it was very hot. It smelt the rocks and because of that the rocks went up. This produced the movement of the plates

Wegener found different facts to explain his theory:

-Among the fosils of plants and animal species that scientists found since 19th century in different continents some of them were very similar.

-He saw that if they got together all the continents the rest of the glaciers that there were in the continents fit with each other.

-He saw that all the continents together  made a puzzle. Firstly, he saw that it didn't fit because it was irregular but finally he saw that it fit.

We have 15 principal plates in the Earth some of them are biggers than the others. Most of them they are mixed plates they have oceanic lithospheres and continental lithospheres but we have also the pacific plate that is only formed by the pacific oceans it hasn’t any continental lithosphere .

We have three type of waves but the waves p and the wafev s are the most important. Ondas P moves in horizontal and waves S moves in vertical.

The waves rayleight and love waves are the third type of waves.  The first one move like a sea wave and the second one moves like a snake.

This waves cause different reliefs in the our Planet, MOUNTAINS RANGES, ISLANDS AREAS,OCEAN RIDGES, VOLCANOES… But these process are too slow for our life time so we can’t see them, but we know that there is a constant movement that change our planet day by day.

The mountains are formed when two continental plates crash strongly, they are not heavy enough to immerse they just push its other. The sediments of these plates are accumulated forming a big relief what we call mountains . Through the years the mountains can get bigger and bigger, what is happening now in Himalaya.
Subduction. This is when one continental or ocean plate hit one ocean plate. The oldest or heaviest one goes under the ocean plate. This causes different estructures: when both are ocean plates this made island arc; for example, Mariana island. The other one is when one is contiental and the other one is ocean, this causes volcano mountains; for example, los Andes.

The volcano is a way that the Earth use to expel heat and some gases. When the magma goes up to the lithosphere it creates a magma chamber that push the surface and forms the volcano where the lava is emerged. This relief is usually found where tectonic plates are converging or diverging. We also can found underwater volcanoes that often create islands like Hawaii.
NATURAL DISASTERS:

An earthquake is the shaking of the surface of the Earth which can destroy big buildings and kill thousands of people. They are measured by seismometers, according to the local magnitude scale magnitude 3 is almost imperceptible and magnitude 7 can cause serious damages. The largest earthquake in historic time have been of magnitude over 9, in Japan.

A tsunami , also known as a seismic sea wave, is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean. Tsunamis generally consist of a series of waves with periods ranging from minutes to hours. Wave heights of tens of meters can be generated by large events. Although the impact of tsunamis is limited to coastal areas, their destructive power can be enormous and they can affect entire ocean basins


A volcano apart from expelling magma it can also create big clouds that cause chemical reactions which damage the stratosphere and can destroy ozone. For example the biggest volcano of Iceland had created a really big black cloud in 2010 that led to air travel disruption northwest Europe for six days and 800 people were evacuated.

SEISMIC RISKS:

Every day around 25 earthquake happen in the Earth, but most of them are of low magnitude. But the areas where there is a big risk of seismic activity are in the sides of tectonic plates and they formed what is called the ring of fire.

Because of alll this facts that we explained  in the future there will be a different map. For example,we are going to be further from USA
