Unit 2 Study Guide: LithospherePart 1: Rock Cycle1. List the 3 main types of rocks. a. b. c.2. Which type of rock is characterized by a “layered” look due to the sediments being deposited in layers over long periods

of time? ___________________3. Which type of rock is formed under extreme heat and pressure? ________________4. Metamorphic and igneous rock are turned into sediment by the processes of _______________ and _______________.5. Magma is formed by melting rock below the earth’s surface. When it reaches the earth’s surface it is called __________.6. Label the Rock Cycle diagram Word bank: magma, sedimentary rock, igneous rock, sediment, heat & pressure, weathering & erosion

Part 2: Plate Tectonics

7. Idea which states that the earth’s crust and ______ mantle are composed of rocky plates which are moving in relation to each other.

8. Describe the theory of continental drift.

9. The lithosphere is composed of the ________ and upper ______.

10.11. The boundaries between the plates are called plate boundaries and there are _____ types.12. Almost all volcanoes and __________________ occur along plate boundaries.13. Seafloor ________ refers to the action of two oceanic plates moving _________ from each other at a ________

boundary.14. When an oceanic plate collides with a continental plate, the ______ plate is forced under the _____________ plate in a

process called subduction.15. Deep-sea trenches are formed when two plates come together, or ____________. As the plates push against each

other they create a deep trench such as the Marianas trench in the Pacific Ocean which is _______ miles deep.16. Oceanic ridges are formed at a ___________ plate boundary. As the plates move apart, magma rises to the surface

and creates new crust.17. Mountain ranges are formed at a ____________ plate boundary.18. Label and describe each of the types of plate boundaries.19. What is a hot spot?

Part 3: Earthquakes20. Anatomy of an Earthquake: Label the parts of the earthquakeword bank: crust, mantle, P (primary), S (secondary), focus, epicenter21. A machine that records the movements of an earthquake is

called a ____________________; the recording the make is called a _______________.

22. Seismograms are useful for determining the ____________ (size) and location of an earthquake. This is done by reading the P and S waves to see how far they’ve traveled, how much time has passed between them, and how much motion they have caused.
