VOICE ONE:  
Scientists say the surface of the Earth is cracked like a giant eggshell. They call the pieces tectonic plates. As many as twenty of them cover the Earth. The plates float about slowly, sometimes crashing into each other, and sometimes moving away from each other.
When the plates move, the continents move with them. Sometimes the continents are above two plates. The continents split as the plates move.
(MUSIC)
VOICE TWO:
Tectonic plates can cause earthquakes as they move. Modern instruments show that about ninety percent of all earthquakes take place along a few lines in several places around the Earth.
These lines follow underwater mountains, where hot liquid rock flows up from deep inside the planet. Sometimes, the melted rock comes out with a great burst of pressure. This forces apart pieces of the Earth's surface in a violent earthquake.
Other earthquakes take place at the edges of continents. Pressure increases as two plates move against each other. When this happens, one plate moves past the other, suddenly causing the Earth's surface to split.
VOICE ONE:
One example of this is found in California, on the West Coast of the United States. One part of California is on what is known as the Pacific plate. The other part of the state is on what is known as the North American plate.
Scientists say the Pacific plate is moving toward the northwest, while the North American plate is moving more to the southeast. Where these two huge plates come together is called a fault line.
The name of this line between the plates in California is the San Andreas Fault. It is along or near this line that most of California's earthquakes take place, as the two tectonic plates move in different directions.
The city of Los Angeles in Southern California is about fifty kilometers from the San Andreas Fault. Many smaller fault lines can be found throughout the area around Los Angeles. A major earthquake in nineteen ninety-four was centered along one of these smaller fault lines.

VOICE TWO:  
The story of plate tectonics begins with the German scientist Alfred Wegener in the early part of the twentieth century. He first proposed that the continents had moved and were still moving.
He said the idea came to him when he observed that the coasts of South America and Africa could fit together like two pieces of a puzzle. He proposed that the two continents might have been one, then split apart.
Later, Alfred Wegener said the continents had once been part of a huge area of land he called Pangaea. He said the huge continent had split more than two hundred million years ago. He said the pieces were still floating apart.
VOICE ONE:
Wegener investigated the idea that continents move. He pointed out a line of mountains that appears from east to west in South Africa. Then he pointed out another line of mountains that looks almost exactly the same in Argentina, on the other side of the Atlantic Ocean. He found fossil remains of the same kind of an early plant in areas of Africa, South America, India, Australia and even Antarctica.
Alfred Wegener said the mountains and fossils were evidence that all the land on Earth was united at some time in the distant past.
VOICE TWO:
Wegener also noted differences between the continents and the ocean floor. He said the oceans were more than just low places that had filled with water. Even if the water was removed, he said, a person would still see differences between the continents and the ocean floor.
Also, the continents and the ocean floor are not made of the same kind of rock. The continents are made of a granite-like rock, a mixture of silicon and aluminum. The ocean floor is basalt rock, a mixture of silicon and magnesium. Mister Wegener said the lighter continental rock floated up through the heavier basalt rock of the ocean floor.
VOICE ONE:
Support for Alfred Wegener's ideas did not come until the early nineteen-fifties. American scientists Harry Hess and Robert Dietz said the continents moved as new sea floor was created under the Atlantic Ocean.  
They said a thin valley in the Atlantic Ocean was a place where the ocean floor splits. They said hot melted material flows up from deep inside the Earth through the split. As the hot material reaches the ocean floor, it spreads out, cools and hardens. It becomes new ocean floor.

The two scientists proposed that the floor of the Atlantic Ocean is moving away from each side of the split. The movement is very slow -- a few centimeters a year.
In time, they said, the moving ocean floor is blocked when it comes up against the edge of a continent. Then it is forced down under the continent, deep into the Earth, where it is melted again.
Harry Hess and Robert Dietz said this spreading does not make the Earth bigger. As new ocean floor is created, an equal amount is destroyed.
VOICE TWO:
The two scientists also said Alfred Wegener was correct. The continents move as new material from the center of the Earth rises, hardens and pushes older pieces of the Earth away from each other. The continents are moving all the time, although we cannot feel it.
They called their theory "sea floor spreading." The theory explains that as the sea floor spreads, the tectonic plates are pushed and pulled in different directions.

VOICE ONE:
The idea of plate tectonics explains volcanoes as well as earthquakes. Many of the world's volcanoes are found at the edges of plates, where geologic activity is intense. The large number of volcanoes around the Pacific plate has earned the name "Ring of Fire."
Volcanoes also are found in the middle of plates, where there is a well of melted rock. Scientists call these wells "hot spots." A hot spot does not move. However, as the plate moves over it, a line of volcanoes is formed.
The Hawaiian Islands were created in the middle of the Pacific Ocean as the plate moved slowly over a hot spot. This process is continuing, as the plate continues to move.
VOICE TWO:
Volcanoes and earthquakes are among the most frightening events that nature can produce. More than one thousand people were killed when a powerful earthquake struck western Indonesia at the end of September. Thousands more were injured or left without homes because of the earthquake. At times like these, we remember that the ground is not as solid and unchanging as people might like to think.

Health: Now, an Update on Those New Year's Resolutions

This is the VOA Special English Health Report.
People who stop smoking often replace cigarettes with food. A new study says the weight they gain may increase their diabetes risk in the short term.
Type two diabetes is common in people who eat too much and exercise too little and those with a family history of it. Smoking is another risk factor. But quitting smoking may carry a temporary risk.
The study found that smokers who quit had a seventy percent increased risk of developing the disease in the first six years. That was compared to those who had never smoked.
The risks were highest in the first three years. And the risk returned to normal after ten years of not smoking.
The researchers say weight gain is probably to blame for the increase. But they say smokers should stop anyway -- and the real message is not to even start.
Type two diabetes interferes with the body's use of insulin. The substance produced by the pancreas normally lowers blood sugar during and after eating. Over time, high blood sugar can lead to blindness, kidney failure, heart disease and nerve damage.
The study is from the Johns Hopkins University School of Medicine. It appears in the Annals of Internal Medicine.
Another American study says obesity has become as great a threat to quality of life as smoking. It compared losses in what are called "quality-adjusted life years." The study found that losses from obesity are now equal to, if not greater than, those from smoking.
These days, there are fewer smokers in the country but more people who are extremely overweight. The findings are based on questions about health-related quality of life in government telephone surveys.
The study is from Columbia University and the City College of New York. It appears in the American Journal of Preventive Medicine.
And another study has linked each hour of watching television daily to an eighteen percent increased risk of death from heart disease. The study of adults in Australia also found an increased risk of death from others causes. The findings are published in Circulation: Journal of the American Heart Association.
Lead author David Dunstan at the Baker IDI Heart and Diabetes Institute in Victoria says the body was designed to move. He says even if people have a healthy body weight, sitting for long periods of time still has an unhealthy influence on blood sugar and blood fats.

How Culture Affected Shakespeare, and He Affected Culture
By Dana Demange

VOICE ONE:
I'm Steve Ember.
VOICE TWO:
And I'm Barbara Klein with EXPLORATIONS in VOA Special English. Today, we complete our story about the influential English writer William Shakespeare. He wrote plays and poems during the late fifteenth and early sixteenth centuries. They remain very popular today.
VOICE TWO:
Last week, we talked about Shakespeare's history, his plays, and his poems. Today, we talk about the events and cultural influences that affected Shakespeare and his art. We also discuss the countless ways his works have influenced language and popular culture.
VIOLA: "Master Shakespeare ...
[Dancing]
Good sir, I heard you are a poet ...
[Shakespeare smiles, silent]
But a poet of no words?"
VOICE ONE:
That was part of a dancing scene from the popular nineteen ninety-eight movie "Shakespeare in Love." The film suggests one way in which Shakespeare might have been influenced to write "Romeo and Juliet:" because of his relationship with a brave and lovely woman. The movie is only very loosely based on real events, but it is a wonderful story.
VOICE TWO:
Many of Shakespeare's works were influenced by earlier writings. During this time, students would probably have learned several ancient Roman and Greek plays. It was not unusual for writers to produce more current versions of these works. For example, in his play "The Comedy of Errors" Shakespeare borrows certain structural details from the ancient Roman playwright Plautus.  
VOICE ONE:
For his tragic play "Macbeth," Shakespeare most likely used a work on Scottish history by Raphael Holinshed for information. It is also no accident that this play about a Scottish king was written a few years after James the First became King of England in sixteen-oh-three. This new ruler was from Scotland and London was alive with Scottish culture. Shakespeare may have borrowed from other writers, but the intensity of his imagination and language made the plays his own.
