I'm really confused about these two questions:
Use the following plate boundary graphic for questions 13 - 14.
It won't let me post the link-
13. What type of plate boundaries are A, C, and D?
A. Convergent
B. Divergent
C. Transform fault
D. All of the above
14. What type of crustal feature(s) will form at plate boundary D?
A. Oceanic volcanoes and island arcs
B. Mid-ocean ridges and rift valleys
C. Trench
D. Volcanic mountains
Just add h t t p s to the beginning of the link and it should show you the picture.
We do not click links, because of the potential danger of doing so.
To answer question 13, you need to identify the types of plate boundaries represented by the locations A, C, and D in the plate boundary graphic. Without the graphic, I can provide a general explanation of the different plate boundaries to help you understand which options are possible.
1. Convergent Boundaries: This type of boundary occurs when two tectonic plates collide. There are three types of convergent boundaries:
- Oceanic-Continental: When an oceanic plate subducts (goes beneath) a continental plate, it typically forms a trench and a volcanic mountain range.
- Oceanic-Oceanic: When two oceanic plates collide, they can form a trench and volcanic island arcs.
- Continental-Continental: When two continental plates collide, the crust is too buoyant to subduct. As a result, it forms massive mountain ranges and often leads to the formation of faults.
2. Divergent Boundaries: This type of boundary occurs when two tectonic plates move away from each other. It leads to the formation of new crust from magma that rises to fill the gap. Divergent boundaries can form mid-ocean ridges or rift valleys.
3. Transform Fault Boundaries: This type of boundary occurs when two plates slide against each other horizontally. It does not create or destroy crust. Transform boundaries are associated with faults and often cause earthquakes.
To answer question 13, you would need to determine whether A, C, and D represent convergent, divergent, transform fault boundaries, or a combination of them. Unfortunately, without the plate boundary graphic you mentioned, I cannot provide a specific answer.
Regarding question 14, the plate boundary D is given. You need to identify the crustal feature(s) that are likely to form at that specific boundary. Again, I cannot provide a specific answer without the plate boundary graphic, but I can explain the general possibilities.
Option A - Oceanic volcanoes and island arcs: This is typically associated with oceanic-oceanic plate boundaries when one plate subducts beneath another, leading to volcanic activity and the formation of island arcs.
Option B - Mid-ocean ridges and rift valleys: This feature is common at divergent boundaries where two plates move apart, creating a gap that is filled with magma.
Option C - Trench: Trenches are formed at convergent plate boundaries when one plate subducts beneath another, causing a deep oceanic trench to form.
Option D - Volcanic mountains: These can form at convergent boundaries when one plate subducts beneath another, leading to volcanic activity and the formation of mountain ranges.
To identify the correct answer for question 14, you would need to determine the specific crustal features associated with plate boundary D. Unfortunately, without the plate boundary graphic, it is challenging to provide a definitive answer.
