• Cementation and Lithification

• None of the above

2. How is a metamorphic rock formed?

• When weathered particles of small rocks are layered, compressed, and cemented.

• Intrusive igneous rock forms inside the crust and Extrusive igneous rock forms on top of the crust.

• High heat and pressure

• A new ocean floor forms along cracks in the ocean crust as molten material erupts from the mantle spreading out and pushing older rocks to the side of the cracks.

How is a sedimentary rock formed?

• When the asthenosphere is unevenly heated.

• Molten lava cools to a solid and crystalizes.

• When rocks change due to the heat and pressure of being buried deep underground.

• Weathering, Erosion, Deposition, Compaction, and Cementation.

4. What is the difference between an intrusive igneous rock and an extrusive igneous rock?

• A new ocean floor forms along cracks in the ocean crust as molten material erupts from the mantle spreading out and pushing older rocks to the side of the cracks.

• earthquakes occur

• Intrusive: Magma cooled underground

  Extrusive: lava cooled above ground.

• They are both rocks!

5. How are the three major rock groups classified?

• Igneous, Metamorphic, Sedimentary rocks

• Rocks are classified in three groups depending on how they are formed.

• There aren't any groups, they are just rocks! What are you talking about?!

• Determined by the strength and epicenter of an earthquake.

6. How is new ocean crust formed?

• By the movement of tectonic plates away from each other
• Through the evaporation of seawater
• Seafloor spreading through the solidification of magma at mid-ocean ridges.
• By volcanic eruptions on land

7. On which type of boundary are mid-ocean ridges located?

• Transform boundaries
• Divergent boundaries
• Convergent boundaries
• Subduction boundaries

8. What happens to Earth’s magnetic field over time?

• It disappears completely over time.
• It remains constant over time.
• It reverses its polarity over time.
• It becomes stronger over time.

9. What is seafloor spreading?

• The process by which the seafloor is formed through erosion and sedimentation
• The process by which new oceanic crust is formed through volcanic activity and then gradually moves away from the mid-ocean ridge.
• The process by which the seafloor sinks into the ocean due to gravitational forces
• The process by which the seafloor is pushed upwards by tectonic forces

• Divergent and Convergent Boundaries
