Explanation:
The volcanic activity refers to the eruption of magma at the surface of the ocean floor and continental land areas, forming volcanoes.
Some of the tectonic settings that are associated with volcanic activity are as follows-
- Mantle plumes- These are the large uprising bodies of magma that are generated due to the formation of convection current in the mantle. These are localized body and are located away from the tectonic boundaries. For example, Hawaii is formed as the plates moved over the mantle plumes.
- Continental rifts- This refers to the eruption of magma at the surface of the continents, due to the divergent motion of two continental plates. It results in the formation of a rift, rift valley and then later forms an ocean.
- Island arcs- These are formed due to the collision of two oceanic plates, where the volcanoes are formed on the lighter oceanic plate due to the rising up of magma.
- Continental arcs- These are formed due to the collision between an oceanic and a continental plate, where the volcanoes are formed due to the uprising of magma in the lighter continental plates.
Answer:
D) The new metamorphic rock would have the approximate same mass as the igneous rock.
Explanation:A metamorphic rock is a type of rock formed under a high temperature of above 150-200 degrees and pressure of over 1000bar, this process of Subjecting certain rock types to very high temperature in order to lead to the formation of a new Rick known as metamorphic rock is called METAMORPHISM. example inclutes
Granulite,slate, marble etc.
Igneous rocks are rocks formed as a result of the solidification of molten magma.
I think its California let me know if this is correct
