Question

which geologic feature is formed from divergence?
volcanoes
trenches
volcanic islands
new seafloor

Explanation:

To solve this, we analyze each option:

• Volcanoes: Often form at convergent boundaries (subduction zones) or hotspots, not mainly from divergence.
• Trenches: Form at convergent boundaries (subduction), where one plate subducts under another.
• Volcanic islands: Many form at convergent boundaries (e.g., island arcs at subduction zones) or hotspots.
• New seafloor: At divergent boundaries (like mid - ocean ridges), tectonic plates move apart. Magma rises from the mantle, fills the gap, and solidifies to form new oceanic crust (new seafloor).

Answer:

D. new seafloor
