Earth processes have not changed over time. The way things happen now is the same way things happened in the past. Mountains grow and mountains slowly wear away. The same process is at work the same as it was billions of years ago. As the environment changes, living creatures adapt. They change over time. Some organisms may not be able to adapt. They become extinct. Becoming extinct means they die out completely. Some geologists study the history of the Earth. They want to learn about Earths past. They use clues from rocks and fossils. They use these clues to make sense of events. The goal is to place things in the order they happened. They also want to know how long it took for those events to happen.

What happens to the living creature that fails to adapt to changes?

Allan sat down at his desk and pulled the chair in close. Opening a side drawer, he took out a piece of paper and his inkpot. After filling his pen, Allan looked at his paper in the orange glow from the lantern set back in the desk's right-hand corner. His pen cast a forbidding line of shadow slanting across the page, echoing the inky darkness crouching in the edges of the lantern's struggling glow. The only other illumination came from a lurid moonlight filtered through thin branches and clouds, casting its bone-pale glow onto the pine floorboards. Allan unfolded another page, this one crowded with ranks of letters in tight formation from left to right. The lines of letters stepped into their divisions, in the shape of a story's outline: the loose, dry skeleton of a tale lay exposed beneath their feet, awaiting tendons, muscle and blushing skin. Allan reviewed the troops, all prepared to disembark, their task to form the tale of a young man returning home from Life Abroad to find his childhood friend a bride to-be, thus upsetting the apple cart of his life's plan, clarified of course by his very time away from her he loved best. Although the concept was a simple one, Allan thought it had potential. Besides, the public liked a good, simple romance. Perhaps this will be more saleable, he thought and began to write. They gazed at each other, lost in the rapture of love based so deeply within their hearts that they had never seen it before. "What about Roger?" she asked, knowing that the answer no longer mattered.

What steps did Allan take before writing?

Hannah Harvey was a ten year old that had many friends in school. She lived in New York and enjoyed doing gymnastics and playing soccer. One day, Hannah came home from school and her parents greeted her. She knew that something was different by the expressions on their faces. Even Jackson, Hannah's dog, was acting different. Hannah asked why everyone was being so strange. Hannah's father, who was known as Pop, explained to Hannah that his job was forcing him to move. Hannah did not seem to think this was too big of a deal. Then, Hannah's mother explained that they were moving to Kenya. Kenya, she explained, was a place in Africa and life would be very different there. As Hannah began to cry thinking about all of her friends at home, Hannah's mother calmed her with a gentle touch. Jackson began howling as Hannah cried, but was also calmed by Hannah's mother. Hannah spent the next two weeks visiting her friends and saying her goodbyes. She did not know the next time she would be home. She cried very hard when she said goodbye to her best friend, Susan. Susan did not quite understand where Kenya was, but promised to visit Hannah. The next day, Hannah boarded a plane with her family. At first, they thought that Jackson could not come with them. However, Hannah worked hard and helped make sure that he had all of his shots so that he could come. After he had them all, the airport said it was OK for Jackson to come! The Harvey family left and off they went across the ocean to begin their new life in Kenya.
How was Jackson able to come with the family to Kenya
