Imagine a glass of your favorite drink that never became empty. Now think about what really happens. You take a drink and there is less in the glass. You keep drinking and soon it is all gone. Good thing you have more to refill your glass. What if there would never be any more of your favorite drink. What would you do? Now you know the difference between renewable and non-renewable. Its too bad that many things here on Earth will run out. This includes some of our natural resources we depend on. Things like oil will not last forever. There is a limited supply. Someday, we will run out, so then what? At current rates of use, coal will last about 300 years. Petroleum will be used up in just a few decades.

Does the Earth have other none renewable resources we depend on other than oil?

William C. Walbrecher Jr., an executive at San Francisco-based 1st Nationwide Bank, was named president and chief executive officer of Citadel Holding Corp. and its principal operating unit, Fidelity Federal Bank. The appointment takes effect Nov. 13. He succeeds James A. Taylor, who stepped down as chairman, president and chief executive in March for health reasons. Edward L. Kane succeeded Mr. Taylor as chairman. Separately, Citadel posted a third-quarter net loss of $2.3 million, or 68 cents a share, versus net income of $5.3 million, or $1.61 a share, a year earlier. The latest results include some unusual write-downs, which had an after-tax impact of $4.9 million. Those included costs associated with the potential Valley Federal Savings and Loan Association acquisition, which was terminated on Sept. 27, 1989. In addition, operating results were hit by an increase in loan and real estate loss reserves. In American Stock Exchange composite trading, Citadel shares closed yesterday at $45.75, down 25 cents.

What bank was the potential acquisition and what quater was the loss associated with this reported?

Earthquakes seemed to outline a special feature of earth's crust. Earthquakes let scientists know where the crust was moving. This led to the discovery that the Earths crust was broken up into regions, or plates. Earthquakes happen most often along these plate boundaries. This was evidence that continents can move. The movements of the plates are called plate tectonics. The Earths crust is divided into plates. There are about a dozen large plates and several small ones. Each plate is named for the continent or ocean basin it contains. Scientists know he plates are in motion. They now know the direction and speed of this motion . Plates dont move very fast. They move only a few centimeters a year. This is about the same rate fingernails grow. So you might wonder, what could cause this motion? What supplies the energy to cause this change?
To get a sense of how fast plates move, what can you look at on your body?
