What happens to the magma after being pushed upward and exposed at the surface of the ocean floor?
When magma reaches the surface of the ocean floor, it cools and solidifies to form igneous rocks like basalt. The rapid cooling of magma at the surface allows for the formation of characteristic features like pillow basalts and seafloor spreading ridges. Over time, these rocks may become buried, eroded, or further altered by geologic processes.
What causes material to form at a mid-ocean ridge on the ocean floor?
New material forms on the ocean floor of the mid-ocean ridge due to plate tectonics and volcanic activity. Volcanic eruptions deposit cooled magma on the ocean floor.

Hardens to form new rock at mid-ocean ridges?
Sea- Floor Spreading molten material erupts through the valley that runs along the center of some mid-ocean ridges. This material hardens to form the rock of the ocean floor. Mid-ocean ridges an undersea mountain chain where new ocean floor is produced.
What happen to the magma after being pushed upward and exposed at the surface of the ocean floor?
The lava would form pillow basalts.
Does a volcano form when magma reaches earths surface?
That is correct. When magma travels from the mantle to the crust and reaches the surface, that is a volcano.
Mid-ocean ridges which contribute to the process of sea-floor spreading form as a result of .?
Mid-ocean ridges form as a result of tectonic plate divergence, where magma from the Earth's mantle rises to the surface at these divergent boundaries. As the magma cools and solidifies, it creates new oceanic crust, contributing to sea-floor spreading. This process continuously pushes the tectonic plates apart, leading to the formation of new ocean floor and the expansion of ocean basins.
How is new rock added to the ocean floor?
New rock is added to the ocean floor through a process called seafloor spreading, where magma rises from the Earth's mantle at mid-ocean ridges, cools and solidifies to form new oceanic crust. This process helps expand the ocean floor and contributes to the movement of tectonic plates.
What is the way 25-cm manganese nodules form on the ocean floor?
it is either apatite, kimberlite magma precipitation minerals calcite or mica
Location in ocean basin where new ocean floor is formed?
New ocean floor is formed at mid-ocean ridges, which are underwater mountain ranges where tectonic plates move apart, allowing new magma to rise up and solidify into new crust. This process is known as seafloor spreading.
What causes new material to form on the mid ocean ridges on the ocean floor?
The uplifted sea floor results from convection currents which rise in the mantle as magma at a linear weakness in the oceanic crust, and emerge as lava, creating new crust upon cooling.
