SOE 101 LAB MIDTERM REVIEW QUESTIONS
VERIFIED ANSWERS
What concept related to density explains why we have oceans basins on earths
surface? - Answers - Isostacy
Density is a ratio between which two physical properties of matter? - Answers - Mass
and volume
Which is true?
- [a] Oceanic crust is denser, therefore more of it sinks into the mantle
- [b ] Continental crust is denser, therefore more of it sinks into the mantle
- [ c] Oceanic crust and continental crust have similar densities - Answers - A
Most true statement - Answers - Density is unevenly distributed with oceans located in
areas where crustal material is denser
Make a sentence using continental crust, ocean basins, and isostacy - Answers - there
are ocean basins because oceanic crust is much denser than continental crust,
because of isostasy
What did we not examine in our plate tectonics lab? - Answers - The age distribution of
continental lithosphere
Why did our TA not let us use the terms convergent, divergent, and transform during
your plate tectonics lab? - Answers - The goal of the lab was to help us relate different
lines of geographical evidence
Which type of geophysical evidence most precisely outlines all different types of plate
boundaries? - Answers - Shallow earthquakes
Where would you find active volcanoes? - Answers - At and active plate boundary
where subduction zones are located
Which physical property is not typically used by earth scientists to categorize minerals?
- Answers - Color
What is the term used by earth scientists to describe an igneous rocks with large, visible
mineral crystals? - Answers - Phaneritic - visible crystals
Aphanitic - Answers - no visible crystals
