| Conservative Plate Boundaries | - EXAMPLE: San Andreas Fault and California - WHAT HAPPENS?: Two plates slide past each other - CAUSES: Earthquakes |
| Collision Plate Boundaries | - EXAMPLE: Indo-Australian and Eurasian plates - WHAT HAPPENS?: Two continental plates collide and the two plates buckle - CAUSES: Many earthquakes |
| Destructive Plate Boundaries | - EXAMPLE: Nazca plate and South American plate - WHAT HAPPENS?: Two plates collide, one is subducted under the other - CAUSES: Many earthquakes and volcanoes |
| Constructive Plate Boundaries | - EXAMPLE: Eurasian and North American plates - WHAT HAPPENS?: Rising convection currents pull crust apart forming volcanic ridges - CAUSES: Volcanoes |
| QUESTION: What is a dormant volcano? | ANSWER: An active volcano that is not erupting (Sleeping) |
| QUESTION: What is an active volcano? | ANSWER: A volcano that has erupted in the past 10,000 years |
| QUESTION: What is an extinct volcano? | ANSWER: A volcano that has not erupted in the past 10,000 years |
| QUESTION: What are the layers of the Earth and how many parts are they made of? (3 answers) | ANSWER: 1. Crust; 2 parts (Continental and oceanic plates / tectonic plates) 2. Mantle; 2 parts (Solid upper, liquid lower) 3. Core; 2 parts (Liquid outer, solid inner) |
| QUESTION: What are the two scales for magnitude and what do they measure? | ANSWER: 1. Richter Scale: measures energy 2. Mercalli Scale: measures the effects and impacts |
| SHIELD VOLCANOES: 1. Where are they found? 2. How are they formed? 3. What do they contain? 4. How often do they erupt, is it violent? 5. Describe the shape. | 1. Constructive Plate Boundaries 2. Formed by eruptions of thin, runny lava which flows a long way before solidifying 3. Contain basaltic magma which is very hot with low silica and gas content 4. Erupt frequently; not violently 5: Gently sloping sides, wide base |
| COMPOSITE VOLCANOES: 1. Where are the found? 2. How are they formed? 3. What are they made up of? 4. What do they contain? 5. How often do they erupt, is it violent? 6. Describe the shape. | 1. Destructive Plate Boundaries 2. Eruptions of vicious, sticky lava and ash that doesn't flow far 3. Made up of thick lava and ash 4. Contain andesitic magma (less how but contains lots of silica and gas 5. Erupt infrequently but violently (including pyroclastic flow (mix of ash, gases and rock 6. Steep, sloping sides, narrow base |
| Convection Currents | 1. Core heats molten rock in the mantle 2. Heated rock rises to the surface 3. At the surface, convection currents move the tectonic plates in the crust 4. Molten rock cools, flows back to the core to be reheated |
| EARTHQUAKE IN KASHMIR, 2005: 1. How many dead? 2. How many homeless? 3. Property damage value? 4. How many injured? 5. Was the area remote or accessible? | 1. 75,000 dead 2. 2.8 million homeless 3. $440 millions property damage 4. 75,000 injured 5. Remote, mountainous area |
| EARTHQUAKE IN CALIFORNIA, 1989: 1. How many dead? 2. How many homeless? 3. Property damage value? 4. How many injured? 5. Was the area remote or accessible? | 1. 63 dead 2. 12,000 homeless 3. $10 billion property damage 4. 3757 injured 5. Built-up, accessible area |
