match the feature to the process that formed it
atoll
mid - oceanic ridge
submarine canyon
delta
seafloor spreading
erosion
deposition
underwater volcanism

Explanation:

• Atoll: Formed by underwater volcanism (a volcano forms, then coral grows as it subsides).
• Mid - oceanic Ridge: Formed by seafloor spreading (tectonic plates move apart, magma rises to create new oceanic crust).
• Submarine Canyon: Formed by erosion (erosive forces like turbidity currents carve these canyons).
• Delta: Formed by deposition (sediment carried by a river is deposited as the river enters a body of water, creating a delta).

Answer:

• Atoll - Underwater Volcanism
• Mid - oceanic Ridge - Seafloor spreading
• Submarine Canyon - Erosion
• Delta - Deposition
