The Mid-Atlantic Ridge. Potentially the East African Rift system in the future
It is considered to be 'constructive,' because new crust is being formed and added to the ocean floor.
Constructive plate margins are when two plates move away from each other, creating more ocean floor.
Spreading boundaries are places where two plates move apart.
Volcano
Constructive because two tectonic plates pushed together and pushed it up.
A constructive boundary is a type of plate boundary where two tectonic plates move away from each other. This movement creates new crust as magma rises and solidifies, forming features such as mid-ocean ridges. It is associated with seafloor spreading and the formation of new oceanic crust.
SPREADING ZONES Spreading zone occurs in the border of two tectonic plates. This happens when the plates generally move away from each other creating an opening for the magma to force through the surface.
Yes, two tectonic plates moving apart can cause sea floor spreading. As the plates separate, magma rises up to fill the gap, solidifying to form new oceanic crust. This process contributes to the expansion of the ocean basins.
Mountains form at (convergent and divergent) plate boundaries. Two plates can crash together and bend upward, forming a mountain, or lava can harden into rack and build up volcanoes which are mountains.
Seafloor spreading
The spreading of plates from a divergent boundary that divides an existing landmass into two separate plates.
This process is called seafloor spreading. As the two plates move apart, magma rises from the mantle to create new crust at the mid-ocean ridge. This process helps explain the movement of Earth's tectonic plates and the reshaping of the ocean floor.
