Question details

For this assignment, you will do the concept sketches using information from the Internet. The three topics and recommended websites for each topic are listed below. For each topic, complete an one page (singled sided) concept sketch that includes the name of the topic and your name. You must do a concept sketch for each of the following topics (for a total of three concept sketches). Remember that a concept sketch consists of a sketch (or series of sketches), labels, and complete sentences written around the sketch describing the important processes or parts of the sketch.

Changes in Life Over Time: For this topic, you will construct a concept sketch illustrating the main events in the history of life as observed from the fossil record. This sketch will show when the main types of organisms, such as trilobites and dinosaurs, appeared in the fossil record and when they becameextinct or whether they are still around today. The change of fossils from older to younger rock layers is commonly called faunal succession, and it is the main way that geologists determine the age of fossil-bearing rock layers.
