Final answer:
Accretion is the process of new land formation at divergent boundaries.
Step-by-step explanation:
The correct answer is Accretion.
Accretion is the process by which new land is formed beneath the plates at divergent boundaries.
When tectonic plates move apart at divergent boundaries, magma rises from the mantle to fill the gap. As the magma cools, it solidifies and forms new land. This process of adding new land through volcanic activity and cooling magma is known as accretion.
