Summary
This document contains a series of questions and answers about Earth's interior, geothermal energy, and the rock cycle. The questions cover a range of topics, including the composition and density of Earth's layers, the processes that create Earth's magnetic field, and how different types of rocks form.

Earth’s Interior 1. Fill out the Table: Earth’s Interior Layer Depth (km) Density Range Oceanic Crust 5-15 km 3 g/cm^3 Continental Crust 30-50 km 2.7-2.9g/cm^3 Mantle 2900 km 3.4-5.6g/cm^3 Outer Core 5150 km 9.9-12.2g/cm^3 Inner Core 6378 km 12.8-13.1g/cm 2. Explain how seismic wave information allows scientists to infer each layer's characteristics. 3. Define geothermal energy: 4. What is the main heat transfer method in which geothermal energy is transferred? 5. What are the 2 main sources of geothermal heat? 6. Explain how the liquid outer core movement allows the earth to create a magnetic field. 7. Compare and contrast the composition and physical states of the Earth’s inner and outer core. Thermal Convection in Earth's Interior- Use the data table below to answer questions 8-10 8. Based on the data table, which layer of the Earth has the highest density and what is its value? 9. How does the temperature of the outer core compare to that of the mantle, and what implications does this have for thermal convection in Earth's interior? 10. Explain how the composition of the inner core contributes to the overall thermal convection process within the Earth. Rock Cycle and Minerals 11. What is the relationship between the temperature at which a mineral crystallizes and the sequence of Minerals crystallizing from magma? 12. Describe the silica content in ultramafic Igneous rocks. 13. Which type of Igneous rocks melts at lower temperatures? 14. What are the minerals that would crystalize in Granite? 15.Describe how an igneous rock can become a sedimentary rock. 16. Explain the role of heat and pressure in the formation of metamorphic rocks. 17. How does the rock cycle contribute to the recycling of Earth's materials? 18. The diagram below represents the intensity of the shaking that occurs on different Earth surfaces during the same earthquake. The greatest earthquake hazard to homes exists when they are built on: Phenomenon: Bowen's Reaction Series in Igneous Rock Formation - Use the data table below to answer questions 19-21 19 19. Based on the data table, which igneous rock type has the highest melting point, and what does this indicate about its mineral composition? 20. If magma cools slowly, which type of rock is likely to form, and what minerals would you expect to find in it? 21. How does the position of basalt in Bowen's Reaction Series relate to its mineral content and melting point compared to granite.
