Sea Floor Spreading
Sea floor spreading creates new oceanic crust at mid-ocean ridges. Magma rises to the surface, cools, and solidifies to form new crust as tectonic plates move apart. This process contributes to the continuous expansion of the ocean floor.
Sea Floor Spreading
As the sea floor spreads, the old ocean floor gets pushed out, which makes the plates move.
The sea floor, or sea bed.
Derr! there called sea mount's.
Sea floor spreading occurs at mid-ocean ridges.
Sea floor spreading occurs when new oceanic crust is formed at mid-ocean ridges and pushes the existing crust apart. As the new crust cools and solidifies, it creates a symmetrical pattern where the ocean floor becomes wider. This process alters the shape of the ocean floor by creating a series of parallel ridges and valleys.
When magma rises through sea floor rifts, it cools and solidifies into new oceanic crust as part of the process known as seafloor spreading. This creates new crust at the boundaries of tectonic plates, contributing to the continual movement and renewal of the Earth's outer shell.
