which often accompany large earthquakes, as well as collapses of volcanic edifices, can also disturb the overlying water column as sediment and rock slump downslope and are redistributed across the sea floor. Similarly, a violent submarine volcanic eruption can uplift a water column and generate a tsunami.
Large landslides and cosmic-body impacts can disturb the water from above, as momentum from falling debris is transferred to the water into which the debris falls. Generally speaking, tsunamis generated from these mechanisms, unlike the Pacific-wide tsunamis caused by some earthquakes, dissipate quickly and rarely affect coastlines distant from the source area. However if the landslide or cosmic body is large enough, it will create a megatsunami. A megatsunami is a tsunami, usually caused by a collapsing island, asteroid impact, or huge chunks of ice falling into a large body of water, and is hundreds of meters high.

Tsunamis can be generated when the sea floor abruptly deforms and vertically displaces the overlying water. Tectonic earthquakes are a particular kind of earthquake that are associated with the earth's crust deformation; when these earthquakes occur beneath the sea, the water above the deformed area is displaced from its equilibrium position.
Waves are formed as the displaced water mass moves under the influence of gravity to regain its equilibrium. When large areas of the sea floor elevate or subside, a tsunami can be created. Large vertical movements of the earth's crust can occur at plate boundaries. Plates interact along these boundaries called "faults". Around the margins of the Pacific Ocean, for example, denser oceanic plates slip under continental plates in a process known as subduction. Subduction earthquakes are particularly effective in generating tsunamis.

It crops up in our speech dozens of times every day, although it apparently means little. So how did the word "OK" conquer the world, asks Allan Metcalf.
"OK" is one of the most frequently used and recognised words in the world.
It is also one of the oddest expressions ever invented. But this oddity may in large measure account for its popularity.
It's odd-looking. It's a word that looks and sounds like an abbreviation, an acronym.
We generally spell it OK - the spelling okay is relatively recent, and still relatively rare - and we pronounce it not "ock" but by sounding the names of the letters O and K.
Visually, OK pairs the completely round O with the completely straight lines of K.

Is it a social network or a content distribution platform? CEO of Twitter Evan Williams doesn't seem to think it's a social network.
A social network is a piece of technology that facilitates communication through existing social connections. You can share messages, photos and events with your friends, people you already know. Facebook is designed for "strong" connections, people you actually know well in real life.
A content distribution platform is a system that provides users with relevant information and links, and that gives content publishers a way to get their content to interested consumers. TV is probably the most obvious example, but RSS is a web-based version.

immy Jump, a man notorious for his pitch invasions of several major sporting events over the years, struck again moments prior to the 2010 World Cup Final between Spain and the Netherlands.
The man's real name is Jaume Marquet Cot. He has already crashed notable events such as the Euro 2004 final, the 2007 Champions League final, and the 2008 French Open men's final, when he jumped the fence during the second set and danced around like a looney in front of Roger Federer donning an FC Barcelona flag.
During Sunday's World Cup final, Jimmy jumped onto the field wearing a red hat and a T-shirt reading 'Jimmy Jump Against Racism.' He tried to grab the World Cup trophy, moments before the Spain and Netherlands players were due to walk out at Soccer City for the tournament's final match.

Firstly, you must discover what are those standing and lasting values that make you who you are. What things interest you or what things make you want to stop as soon as you begin. Choosing a career is all about you, because if you don't know who you are as an individual, it's going to be extremely hard to convince your potential employer to entrust you with a job.
For some of us, we value our families and the ability to schedule work around life or for some it may be the need to work around certain types of people, rather than others. Whatever those values and ideals fit you, you must be comfortable with yourself and willing to try new things!
Secondly, you must figure out what you are good at and what brings out the best of your abilities. Obviously, if you are great at painting artwork, but really can't stand working outside in the scorching heat, then you probably don't want to apply for a job as a car mechanic. There are many ways to figure out what you are good at, simply just by asking yourself what are your likes and dislikes, your expectations for your dream career, and what steps you would have to take to get there.
Whenever someone comes up to me and complains about their job and how they dislike it so much, I always ask why you are still doing it. Work in a field that fits your mold and who you are, not based on pay or some other factor.

After a little fumbling with the envelope, the head of the International Olympic Committee has just announced the venue for the 2016 Olympics - Rio de Janeiro. It all seems a confirmation of the mood of the moment - Brazil is deeply fashionable and on the way up; and the shine has come off Barack Obama, who turned up in person to lobby for Chicago - only to see his home town eliminated early.
Poor Obama, he really didn’t deserve this. I bet he now regrets going all the way to Copenhagen to lobby for Chicago. His great trump-card was meant to be his global popularity. But the International Olympic Committee had no trouble in brushing him aside. I’m afraid this is all going to play into the gathering conservative narrative in the US of Obamas a naive dupe, who grovels in front of foreigners - and gets nothing back in return. It seems to be setback after setback for the US president at the moment - health-care, Iran, the Afghanistan mess, unemployment up at nearly 10%.
As for Brazil - never has the country been so fashionable. The Brazilians are hosting the World Cup in 2014 and now the Olympics, two years later. They provide the first letter of the much-touted group of emerging economic superpowers - the BRICs. They are key members of the G20. In Lula, Brazil at last has a leader who is a recognised global figure. He gave the lead-off address at the UN General Ass
