Q: What forms in the ocean from the seafloor spreading?


Read this paragraph and choose the correct option from the provided answers:

In the oceans, plates move apart at mid-ocean ridges. Lava rises upward, erupts, and cools. Later, more lava erupts and pushes the original seafloor outward. This is seafloor spreading. Seafloor spreading forms new oceanic crust. The rising magma causes the ridge to be buoyant. This is why there is a mountain range running through the oceans. The plates pulling apart cause earthquakes.

 Choices:

- underwater volcanoes

- tsunamis

- earthquakes

- new oceanic crust


A:
new oceanic crust
