1. Continental drift theory and Theory of Plate tectonic

2. Do you know about Pangea?

3. A restless Earth Our planet is active and constantly changing. Pangea: The surface of the earth went through great changes about two hundred million years ago al continents were united forming a big landmass, which we call Pangea or super continent. There are a few theories about how the continents we now know were formed. The most known ones are: Theory of Continental drift The theory of tectonic plates

4. Informative charts Gather in groups of 2 Read pages 40-41 of your history book and write information about the continental drift theory and the tectonic plates theory. Create a chart with information explaining both theories. Put together the map of both theories provided by the teacher. Be creative be informative continental drift theorytectonic plates theory Information:

5. Continental drift theory Created by Alfred Wegner, a German scientist. In the early 1900’s According to the theory: The continents used to formed a big landmass called Pangea Pangea divided in 2 huge parts. North called Laurasia and south Gondwana. Then it kept moving until it took the form of the 7 continents we now know. Wegner’s theory was later modified. https://www.youtube.com/watch?v=QL7LX5-ytOg Google: pangea puzzle online game http://www.geo.cornell.edu/hawaii/220/PRI/continental_puzzle.html http://www.geo.cornell.edu/hawaii/220/PRI/continental_puzzle.html

6. Tectonic plates theory https://www.youtube.com/watch?v=lJiAUvB1vEU According to this theory, the surface of the earth is divided into twelve big plates and some smaller ones. Sometimes one plate pushes another and the land begins to rise up. This is how mountains are formed. Example: two huge tectonic plates collided to form the Himalayas. Another feature of these plates are the creation of volcanoes. Example: openings are formed around some of the plates edges. The magma is trapped below the rocky surface of the plate. When the magma can escape through the openings, creates a volcano. Map p.41 https://www.youtube.com/watch?v=ELd3ebldSTs
