Question

the mid - atlantic ridge is found at a divergent plate boundary. which even is occurring at this location? island chains are being formed. guyots are being destroyed. crust is pushing against crust. a new crust is being formed.

Explanation:

1. Recall the concept of divergent plate boundaries: At divergent boundaries, tectonic plates move apart.
2. Analyze each option:

• "Island chains are being formed" typically occurs at hotspots or convergent boundaries (e.g., subduction zones), not divergent.
• "Guyots are being destroyed" is not related to divergent boundaries (guyots are flat - topped seamounts, and their destruction isn't associated with divergence).
• "Crust is pushing against crust" describes convergent boundaries (where plates collide), not divergent.
• At a divergent plate boundary like the Mid - Atlantic Ridge, magma rises from the mantle, cools, and solidifies to form new oceanic crust as the plates move apart. So "A new crust is being formed" is correct.

Answer:

D. A new crust is being formed. (assuming the options are labeled A - D as per the order: 1. Island chains are being formed. 2. Guyots are being destroyed. 3. Crust is pushing against crust. 4. A new crust is being formed.)
