Question

1. which layer of earth is liquid? a) mantle b) outer core c) inner core d) crust 4. when two plates collide and one sinks under the other, its called a) divergent boundary b) transform boundary c) subduction d) rift valley 5. which mineral is magnetic? a) quartz b) magnetite c) calcite d) gold part 7: creative question imagine you are a rock going through the rock cycle. write 5 - 6 sentences describing your life story. be sure to mention at least three different processes (like melting, erosion, compaction, heat/pressure). part 8: rock id please make your way to the white desk in back and make sure you can identify the rock samples at the table. you will be asked to identify at least 5 rocks for the final exam.

Explanation:

1. The Earth's outer - core is liquid. Mantle is semi - molten, inner core is solid, and crust is solid.
2. When one tectonic plate sinks under another during a collision, it is called subduction. Divergent boundaries are where plates move apart, transform boundaries are where they slide past each other, and rift valley is related to divergent boundaries.
3. Magnetite is a magnetic mineral. Quartz, calcite, and gold are not magnetic.

For the creative question, an example answer: I start as a big rock on the surface. Wind and water cause erosion, breaking me into smaller pieces. These pieces are then carried away and deposited in a low - lying area. Over time, the weight of the layers above causes compaction, turning me into a sedimentary rock. Then, I am pushed deep into the Earth where high heat and pressure transform me into a metamorphic rock. Eventually, I may melt and become magma, starting the cycle anew.

Answer:

1. b) Outer Core
2. c) Subduction
3. b) Magnetite
