What happens to the old oceanic crust as new molten material rises from the mantle?
The older oceanic crust moves away from the spreading center and is eventualy subducted back into the mantle.
In the process of subduction a lithospheric plate descends into the?
mantle at a convergent plate boundary. This subducted plate melts due to the high temperatures and pressures in the mantle. The melted material can rise as magma and create volcanic arcs and mountain ranges on the Earth's surface.
Both slab-pull and ridge-push are mechanisms that cause?
Ocean plates to be subducted into the mantle
What happens to the earth's crust that is subducted?
When the Earth's crust is subducted, it sinks into the mantle at convergent plate boundaries, where one tectonic plate moves beneath another. This subduction process leads to increased temperature and pressure, causing the crust to partially melt and contribute to magma formation. The materials from the subducted crust can also lead to volcanic activity and the creation of mountain ranges over geological time. Eventually, some of the subducted material may be recycled back to the surface through volcanic eruptions or tectonic uplift.
Hotspot volcanoes occur along subduction zones?
False. Hotspot volcanoes form above mantle plumes, which are localized upwellings of hot mantle material. Subduction zone volcanoes form due to the subduction of one tectonic plate beneath another, resulting in magma generation due to the melting of the subducted plate.
What can happen when two oceanic plates converge and one is subducted into the mantle?
When two oceanic plates converge and one is subducted into the mantle, the subducted plate melts due to the high temperatures and pressure, forming magma. This magma can then rise to the surface, leading to volcanic activity. Additionally, the subducted plate can cause earthquakes as it descends into the mantle.

What kind of crust usually goes into the mantle?
Oceanic crust gets subducted into the mantle.
In the process of subduction a lithospheric plate descends into the?
mantle at a convergent plate boundary. This subducted plate melts due to the high temperatures and pressures in the mantle. The melted material can rise as magma and create volcanic arcs and mountain ranges on the Earth's surface.
What happen to the oldest rock on the ocean floor to continue the rock cycle?
Or they get subducted and re-enter the mantle or they get obducted onto continent (the latter being called an ophiolite).
Can metamorphic rocks be part of an isolated system?
No. They will either be subducted into the mantle or uplifted and/or exposed to erosion.
Both slab-pull and ridge-push are mechanisms that cause?
Ocean plates to be subducted into the mantle
Why are convection currents in the mantle?
The convection currents are a result of heat from the interior of the Earth. The rock of the upper mantle known as the asthenosphere is plastic-like but not molten. It acts like a conveyor belt, moving heat from Earth's interior upward, and cooled material downward in a big loop. New crust is created where mantle material reaches the surface at places called mid-ocean ridges. Older, colder oceanic crust is subducted and drawn into the mantle, completing the loop.
What happens to old oceanic crust as molten materials rises from the mantle?
The older oceanic crust moves away from the spreading center and is eventualy subducted back into the mantle.
What happens to rock along converging boundaries?
It is folded and uplifted, or subducted into the mantle, depending on the type of convergent boundary.
