Reorganizing your work an example

The following short assignment, set in a sciences foundation course, seemed a fairly simple task the title, The structure of the earth, indicated a description shape for the writing, and the student assumed that his main job was to collect, select and organize the information. He used three encyclopaedias. After he had drafted the piece on a computer, he printed it out and talked it over with a tutor and together they worked out how it could be organized 

The earth is the 3rd largest planet from the sun and the fifth largest in our solar system. It was formed approximately five billion years ago. Zt is believed to have formed from swirling glouds of dust and gases. The inside of the earth is in constant activity, evidence of this is shown on the surface by way of earthquakes, volcanoes, land shifts and subsidence. 

The earth is flatter at the poles, north and south, than at the equator. Zt revolves around the sun at 18.5 million miles per second and takes roughly 365 days to c nplete a clrouit. It also spins on its axis at lOOO miles per hour and akes about 24 hours to con lete a rotation. 

The earth s surface covers about 197 million sq. Miles. Of this 140 million sq. miles is water and 57 sq miles is land - about 30%. It has an equational circumference of 24, 902 miles, an equatorial radius of 3, 963d miles and a polar radius of 3, 950 miles. Zt has a mass of 5.976 x 1027 grams and a means density of 5.517 grams per cubic oa. (see chart) 

The core consists of an outer and inner part. The outer core starts at about 1800 miles below the crust and is 1400 miles thick. It behaves like a liquid and consists of molten Ircsi. She inner core is 860 miles thick and forms the centre of the earth. Bvidence suggests that this inner core consists almost entirely of extr nely dense iron and nickel (Collier 1995 p. 478).
