Minerals are not classified as metamorphic. The mid-oceanic ridges are generally considered to be areas where new basaltic crust is formed from uprising magma. The basalt is considered an igneous rock in classification.
False. The Earth's radius and surface area do not increase as new oceanic crust is formed at mid-oceanic ridges. Instead, the creation of new crust at mid-oceanic ridges is balanced by the destruction of older crust at subduction zones, maintaining the overall size of the Earth.
Oceanic crust and lithosphere are formed at mid-ocean ridges through the process of seafloor spreading. Magma rises from the mantle and solidifies to create new oceanic crust at these divergent plate boundaries. As the new crust forms, it pushes the older crust away from the ridge axis, creating a continuous process of crust formation and movement.
When oceanic crust is still young, it's relatively warm. The older it gets, the colder it gets. The colder it gets, the less volume it takes in, however, it's still the same amount of matter. This causes a bigger density, thus causing the crust to sink deeper into the mantle.
The color of the rock that forms oceanic crust at mid-ocean ridges is dark gray to black. The rock is primarily basalt, which is a type of igneous rock formed from the solidification of molten lava.
New oceanic crust is continually being created at the Mid-Ocean ridges.
At the oceanic ridges the age of igneous basalt rocks is approximately zero (as that is where they formed) and the rocks get older the farther away. The ages of sedimentary and metamorphic rocks does not correlate reliably with distance from the oceanic ridges like the ages of igneous rocks, because they can form anywhere not mainly at oceanic ridges. Igneous granite rocks are generally formed around continental volcanos not oceanic ridges.

False. The Earth's radius and surface area do not increase as new oceanic crust is formed at mid-oceanic ridges. Instead, the creation of new crust at mid-oceanic ridges is balanced by the destruction of older crust at subduction zones, maintaining the overall size of the Earth.

Spreading ridges
It is true that mid-ocean ridges are underwater mountain ranges. These ridges are where the lithosphere is moving apart and new oceanic crust is being formed.

Divergent boundaries form ocean ridges.
2. Mid Ocean Ridges are the place where new crust is formed. 1. oceanic plates or oceanic crust
Earth's oceanic crust is primarily made up of basalt, which contains minerals such as plagioclase feldspar, pyroxene, and olivine. These minerals form from the solidification of magma that emerges from mid-ocean ridges.
The sequence of rock strips at oceanic ridges is called "oceanic crust." It is formed through the process of seafloor spreading where magma rises through the Earth's crust, solidifies, and creates new crust. This process helps drive the movement of tectonic plates.
The Earth some times oceanic crust is formed by the process of mid oceanic ridges. this process occurs when magma comes from the mantle and cool below oceanic body & form new crust.
