Question

which statement describes divergent boundaries?
○ divergent boundaries are found only on land.
○ subduction occurs at divergent boundaries.
○ plates move toward each other at divergent boundaries.
○ magma flows from cracks in the crust at divergent boundaries.

Explanation:

• Analyze each option:
• Option 1: Divergent boundaries are also found in the ocean (e.g., mid - ocean ridges), so they are not only on land. Eliminate this option.
• Option 2: Subduction occurs at convergent boundaries (where one plate is forced under another), not divergent. Eliminate this option.
• Option 3: At divergent boundaries, plates move away from each other, while at convergent boundaries plates move toward each other. Eliminate this option.
• Option 4: At divergent boundaries, tectonic plates move apart, creating cracks in the crust. Magma from the mantle can rise through these cracks and flow out, which is a characteristic of divergent boundaries.

Answer:

D. Magma flows from cracks in the crust at divergent boundaries. (Note: Assuming the options are labeled A - D in order, with the last option being D. If the original labeling is different, adjust the identifier accordingly, but the text of the option remains the same.)
