Question

Which one of the following lithospheric plates has the least length of convergent boundary?

• A. Pacific
• B. Indian
• C. Antarctic
• D. South American

Hint:

When analyzing convergent boundaries, consider the geographical distribution of the plates and their interactions with other plates.

Answer 1

The Correct Option is C

Step 1: Understanding Lithospheric Plate Boundaries.
Lithospheric plates interact with each other at convergent boundaries, where they either collide, subduct, or slide past each other. Some plates have longer convergent boundaries than others. The Antarctic Plate has the shortest convergent boundary due to its location mostly isolated around the pole with limited boundary interactions.
Step 2: Analyzing the Options.
- Pacific Plate has long convergent boundaries, especially with the North American and Eurasian plates.
- Indian Plate has significant convergent boundaries, including the boundary with the Eurasian Plate.
- Antarctic Plate has the shortest convergent boundary, with fewer significant collisions.
- South American Plate also has a long convergent boundary with the Nazca Plate.
Thus, the correct answer is (C) Antarctic.
Final Answer: \[ \boxed{\text{Antarctic}} \]
