Historical Examples. 1  He was a student working his way to an education, and his example was a help to me. 2  Langdon was a consummate trainer, a student of horse character. 3  Such a student cannot assume that Paul ever took anything for granted.  4 That is what I have never been able to find out, answered the student.
This continues the trend of earthquakes making Earth less oblate. Less oblate means more round. They also found the earthquake decreased the length of the day by 2.68 microseconds. (A microsecond is one millionth of a second.) In other words, Earth spins a little faster than it did before. This change in spin is related to the change in oblateness. It's like a spinning skater drawing arms closer to the body resulting in a faster spin. None of these changes have yet been measured--only calculated. But Chao and Gross hope to detect the changes when Earth rotation data from ground based and space-borne sensors are reviewed. Editor's note: The earthquake discussed in this story spawned deadly tsunamis that killed many tens of thousands of people and left an even greater number hurt and homeless.
The Water Cycle and Climate Change. Among the most serious Earth science and environmental policy issues confronting society are the potential changes in the Earthâs water cycle due to climate change.urthermore, because of warmer temperatures, more precipitation is falling as rain rather than snow. One expected effect of climate change will be an increase in precipitation intensity: a larger proportion of rain will fall in a shorter amount of time than it has historically.
