At divergent boundaries is what metamorphism results from extrusion of basaltic lava?
A metamorphic rock formed from Basalt is Schist. a.k.a. Green Schist
What kind of metamorphism happens at divergent boundaries?
At divergent boundaries, primarily hydrothermal metamorphism occurs due to the interaction of seawater with hot magma and volcanic activity. As tectonic plates pull apart, magma rises to create new oceanic crust, and the circulating seawater can alter minerals in the rocks, leading to changes in their chemical and physical properties. This process is often associated with the formation of features like black smokers and altered mineral deposits.
What are the 2 types of divergent boundaries and what happens in each?
continetal and oceanic
Ore bodies at divergent plate boundaries can be created through what contact metamorphism regional metamorphism hydrothermal process?
Hydrothermal processes are responsible for creating ore bodies at divergent plate boundaries. When water interacts with hot rocks, it dissolves minerals and can concentrate them in fractures and openings, forming valuable ore deposits. This process occurs in hydrothermal vents along mid-ocean ridges where new oceanic crust is forming.
Where are rift boundaries formed at and what happens at them?
A rift boundary is a divergent boundary, where two plates of the earth's crust are moving away from each other. Divergent boundaries occur at mid-oceanic ridges on the sea floor, but usually the term rift is used to describe divergent boundaries on the land. The best known one is in eastern Africa.
What happens divergent boundaries?
divergent boundaries happen when 2 plates move apart or divide
At what four plate boundary types does metamorphism occur?
Metamorphism typically occurs at convergent boundaries, where tectonic plates collide, and at divergent boundaries, where plates move apart. It also occurs at transform boundaries, where plates slide past each other horizontally. Metamorphism can also occur at hot spots, where magma from the mantle rises to the surface.
What happens along divergent boundaries?
along divergent boundaries tectonic plates move apart & rifts are created

How are oceanic ridges form?
divergent boundaries
How are convergent boundaries different from divergent boundries?
convergent boundaries collide but divergent boundaries move away from each other.
What happens to magma divergent boundaries?
At divergent boundaries, two plates move apart from each other and the space that this creates is filled with new crustal material sourced from molten magma that forms below.
Where are rift boundaries formed at and what happens at them?
A rift boundary is a divergent boundary, where two plates of the earth's crust are moving away from each other. Divergent boundaries occur at mid-oceanic ridges on the sea floor, but usually the term rift is used to describe divergent boundaries on the land. The best known one is in eastern Africa.
Where are most divergent boundaries found?
On the seafloor. Yes, the mid oceanic ridges are all divergent boundaries.
