1. VOLCANOES AT HOTSPOTS TECTONIC HAZARDS

2. IN THIS LESSON YOU WILL DISCOVER : (I) The reason why some volcanoes do not occur on plate boundaries. (II) What happens to volcanoes located over a hotspot as they are carried away by the tectonic plate. 2

3. 3 Study the distribution of volcanoes shown on Figure 2. Where is Kilauea located? Kilauea is located in the middle of the Pacific Ocean far from plate boundaries.

4. 4 Underwater volcano Extinct volcanoes

5. WHY? You are going to watch a short video on the formation of hotspot volcanoes. 1- Study activity 1 on the Hotspots worksheet. 2- Watch and listen! 3- Watch the video again to complete your answers! 5- Discuss your answers with the student seated beside you.

6. A FEW KEY WORDS TO HELP YOU Solid part of the mantle Semi-molten part of the mantle (magma) Motion=movement Intrusion: Magma slowly pushes up from deep within the earth into any cracks or spaces it can find. An extinct volcano is not expected to erupt again. Stationary: which doesn’t move. VIDEO Mantle Plume: A column of hot rock rising inside the mantle
