Warm-Up 1) What happens when two cars crash into each other? 2) What happens when you rub your hand against carpet? 3) What happens when you pull apart a Snicker’s candy bar? 4) Why does a hot air balloon rise? Daily Objective • SWBAT explain movement of the lithospheric plates. • SWBAT infer the relationship between the type of plate boundary and the locations of various natural features such as ocean trenches, mountain ranges and mid-ocean ridges. 2 Thought for the day Focus on all that you do, whether the task be big or small. This will lead you to the path of excellence. 3 Agenda • • • • • • Warm-Up (5) Vocabulary Hunt (10) Intro to the Earth’s Interior Movement (8) Notes + Videos (with notes) (20) Plate Boundary Map (20) What Type of Boundary? (10) 4 First…table of contents! Unit 2: Earthquakes & Plate Tectonics Date Title Page 9/22/14 Convection 1 currents and Plate Tectonics Guided Notes with Vocabulary 9/22/14 Plate Boundaries Diagram 2 9/22/14 Tectonic Plates Activity Sheet 3 5 Vocabulary Hunt • On a separate sheet of paper, define the following words using your textbook: – Convective flow – Ridge push – Slab-pull – Subduction zone – Oceanic ridge – Trench – Hot spot When you are done, you will staple this to the back of your page 1 Guided Notes 6 What did the world look like 1 million years ago? http://app.discoveryeducation.com/pl ayer/view/assetGuid/86E95DC72F7F-435A-9C2C-E0B08EC787D8 http://app.discoveryeducation.co m/player/view/assetGuid/BC7708 AF-9C95-4896-AC8CD36F1053D5B3 Plate tectonics • Scientific theory that describes the large-scale movement of the lithosphere 8 Now let’s take a closer look At the earth’s interior 9 Examine the chart of the layers of the Earth and answer the following questions: 1.What is the thickest layer of the Earth? 2.What is the densest layer of the Earth? is this layer found? 3.What is the least dense layer of the Earth? this layer found? Where Where is So… What’s it supposed to look like? 11 What about particles? How do particles change when they are cold and hot? Colder particles Hotter particles THEREFORE: Hotter objects are ___________ dense and colder objects are ____________ dense. YOUTUBE CLIPS Take notes on these clips while you watch! Write down what you see. 1.http://www.youtube.com/watch?v=7xW WowXtuvA (two colors) 2.http://www.youtube.com/watch?v=LNY ggAQ-Zf4&NR=1 (fish tank with floating plate) Convection • The transfer of heat in the asthenosphere due to unequal heat from the core as magma heats up and rises, then cools down and sinks • Responsible for the movement of the tectonic plates Why does it matter? Let’s find out! 16 Take out your notes! • Look at the bottom half of the first page – you should have an empty chart. 17 Fillin’ in the chart… 18 Fillin’ in the chart… 19 Fillin’ in the chart… 20 Let’s look at some examples 21 Convergent Boundaries Oceanic-Continental 22 Convergent Boundaries Continental-Continental 23 Dovergent Boundaries 24 Transform Fault Divergent Convergent 25 Transform Boundaries 26 Let’s see this in action • Fill in the guided notes on your worksheet as we go! • Convergent: http://www.youtube.com/watch?v=nfziy_860 GU • Divergent: http://www.youtube.com/watch?v=0mWQs1 _L3fA 27 Let’s take a deeper look… • With your partner, use the plate boundaries map provided and find the different types of plate boundaries… 28 29 30 31 JUST REMEMBER… Convergent Collide, Divergent Divide, Transform Slide WHAT B=Transform C=Convergent D=Divergent OF TYPE BOUNDARY?

B=Strike Slip Fault C= Subduction Zone D=Divergent Real Life Examples 52 Himalayan Mountains At the border of India and Asia. Tallest mountain range in the world and includes Mount Everest. Himalayan Mountains East African Rift Valley Located in East Africa. Runs for thousands of miles. Has created great lakes and the largest waterfall in the world. This is the beginning of the breakup of a continent. As the rifting continues, it will lengthen and deepen and eventually will split the continent and in two. East African Rift Valley San Andreas Fault The San Andreas Fault is a continental transform boundary that runs a length of roughly 810 miles through California It forms the tectonic boundary between the Pacific Plate and the North American Plate. It is the most studied fault on the planet. San Andreas Fault Exit Ticket Are you ready? 59 Exit Ticket 1. 2. 3. 4. 5. What is convection? In which layer does convection take place?
