Question

at which two plate boundaries is new crust being created? choose 2 answers: a the cocos and caribbean plate boundary b the cocos and nazca plate boundary c the nazca and pacific plate boundary d the nazca and south american plate boundary

Explanation:

New crust forms at divergent plate boundaries, where tectonic plates move away from each other, allowing magma to rise and solidify.

• Option A: Cocos and Caribbean plate boundary is a divergent boundary, creating new crust.
• Option B: Cocos and Nazca plate boundary is a divergent boundary, creating new crust.
• Option C: Nazca and Pacific plate boundary is a transform boundary (plates slide past each other, no new crust formed).
• Option D: Nazca and South American plate boundary is a convergent boundary (one plate subducts, crust is destroyed, not created).

Answer:

A. the Cocos and Caribbean plate boundary
B. the Cocos and Nazca plate boundary
