BIOGEOGRAPHY BIOGEOGRAPHY BIOGEOGRAPHY The study of living things and where (in the WORLD) they live STOP AND WRITE YOUR OWN DEFINITION FOR BIOGEOGRAPHY Now, make a sketch that will help you remember what it means. Throughout the world we find different organisms living in different regions of the globe. Untold tragedies of Continental Drift. Continental Drift • What is the root word for “Continental”? • CONTINENT • What does the word continent mean? • What does the word “drift” mean? • Talk at your table and raise your hand if you can define continental drift without using the words “continent” or “drift”. Current Continental Drift Theory • Plate tectonics, incorporating continental drift, is the ruling theory. • Tectonic plate movement could have occurred very rapidly, and ‘spontaneously.’ This concept is known as catastrophic plate tectonics. Continental Drift Today you will watch a video clip about continental drift. After the clip, I will ask you to name two observations which scientists use to support the theory of continental drift—in other words, two FACTS that support the theory. I want you to summerize these (get rid of all the details and state the main idea). The clip is about 10 minutes long. Continental Drift Talk at your table and write two facts supporting the theory. Summarize these (you don’t need big words). 1. Spreading Ocean Floor 2. Cracks in the earth’s crust Now, write a definition for continental drift, without using the words themselves and IN YOUR DEFINITION ADD TWO FACTS WHICH SUPPORT THE THEORY. Continental Drift Now, make a sketch that will help you remember what it means. Continental Drip? New discoveries could support this theory even more or cause the model to be abandoned. Such is the nature of scientific progress. Scientific models come and go. Dispersal Define the word Write the three ways organisms disperse. DISPERSAL What are three methods of dispersal? Write these on your worksheet. Limits to Dispersal • Turn to page 730-731 • Complete the concept map on the back of your notes • Also, complete the summary box. Rephrase the ideas and generalize in your summary. Underline at least three key terms. Canyon The End The study of Biogeography also involves the study of the different climates of the different regions of the world. What two things make up weather or CLIMATE? The mid-Atlantic Ridge (arrow), clearly visible by satellite imaging.
