What type of rock are made mid-ocean ridges made of?

igneous rock


How did the ridges around Shiprock form?

The ridges around Shiprock, a volcanic rock formation in New Mexico, were formed by the erosion of softer volcanic material surrounding a central volcanic neck. Over time, wind and water eroded the softer rock layers, leaving the harder, more resistant rock of the neck and surrounding ridges exposed. This process created the distinctive spire and ridges that characterize the landscape today. The formation is a remnant of a once-active volcano that erupted approximately 30 million years ago.


What happens the age of rock with distance from the mid ocean ridges?

The age of rock increases with distance from mid-ocean ridges. At the ridges, new oceanic crust is formed through volcanic activity, which is young. As the crust moves away from the ridges, it cools and becomes older. This process is known as seafloor spreading.


What types of rock are mid ocean ridges made of?

The mid-ocean ridges are made almost entirely of basalt, because this is where new oceanic lithosphere is being formed. In fact, oceanic plates in there entirety are made up almost entirely of basalt.(igneous rock)


What plutonic igneous rock forms beneath mid-ocean ridges?

The plutonic igneous rock that forms beneath mid-ocean ridges is primarily gabbro. Gabbro is a coarse-grained rock that crystallizes from magma that cools slowly beneath the Earth's surface, typically associated with the upwelling of magma at mid-ocean ridges. This process contributes to the formation of new oceanic crust as tectonic plates diverge.
