Question

what is the crack in the ocean floor through which magma rises? * options: ridge, rift, rip, rent

Explanation:

To solve this, we analyze each option:

• "ridge" refers to an underwater mountain range, not a crack for magma.
• "rip" is a strong current, not related to magma or ocean floor cracks.
• "rent" means a tear but is not the geological term for the ocean - floor crack with rising magma.
• "rift" is a geological term for a crack or split in the Earth's crust (including ocean floor) through which magma can rise, matching the description.

Answer:

C. rift
