Question

Mark is graphing data collected from satellite images. He notices that a rift valley in the Red Sea keeps getting larger. What type of plate boundary is he mapping?
A
transform boundary
B
convergent boundary
C
divergent boundary
D
collision boundary

Answer 1

Mark is observing a rift valley in the Red Sea that is continuing to grow, which indicates that tectonic plates are moving away from each other. This phenomenon is characteristic of a **divergent boundary** where tectonic plates separate, resulting in the formation of rift valleys and ocean basins.

Thus, the correct answer is:
**C - divergent boundary**.
