Seafloor spreading is associated with which geological feature?

Seafloor spreading is associated with which geological feature?

• A. Continental drift
• B. Abyssal plains
• C. Ocean trenches
• D. Volcanic islands

Answer: (B)

Seafloor spreading is primarily associated with the formation of new oceanic crust at mid-ocean ridges, where tectonic plates are moving apart. This process creates new materials that contribute to the development of abyssal plains, which are flat, deep areas of the ocean floor. As magma rises at these ridges, it cools and solidifies to form new oceanic crust, which gradually spreads outward, leading to the creation of wide, flat expanses in the ocean. Over time, as the seafloor continues to spread and evolve, the abyssal plains can become covered by sediment, further contributing to their flatness. This connection between seafloor spreading and the formation of abyssal plains highlights the dynamic nature of the Earth's geological processes.
