Liquid water is not a mineral
Answer:
A
Explanation:
At convergent boundaries magma is formed where water from a subducting plate acts as a flux to lower the melting temperature of the adjacent mantle rock.
Answer:
Option (2)
Explanation:
The mid oceanic ridge is the region along which two plates moves away from one another. This occurs in the divergent plate boundary. The magma, during this type of plate motion, comes out to the surface of the ocean floor and solidifies immediately due to the lowering temperature, giving rise to the formation of basaltic rocks.
The solidification age refers to the time when the magma last crystallized as it ejected at the ocean floor.
According to the given condition, the magma last solidified nearly 10,000 years back in the mid oceanic ridge, which are considered to be the youngest rocks found along the mid oceanic ridge.
Thus, the correct answer is option (2).
The phrase “Global South” refers broadly to the regions of Latin America, Asia, Africa, and Oceania. It is one of a family of terms, including “Third World” and “Periphery,” that denote regions outside Europe and North America, mostly (though not all) low-income and often politically or culturally mar- ginalized.
