How does the location of a volcano affect the magma composition

Geography
1 answer:
Jlenok [28]3 years ago
7 0

Answer:There are as many types of volcanic eruptions as there are eruptions. Actually more since an eruption can change character as it progresses. Each volcanic eruption is unique, differing in size, style, and composition of erupted material. One key to what makes the eruption unique is the chemical composition of the magma that feeds a volcano, which determines (1) the eruption style, (2) the type of volcanic cone that forms, and (3) the composition of rocks that are found at the volcano. Different minerals within a rock melt at different temperatures. The amount of partial melting and the composition of the original rock determine the composition of the magma. The words that describe composition of igneous rocks also describe magma composition.

Question 6(Multiple Choice Worth 3 points) B If solidification ages at the Mid-Atlantic Ridge are around 10,000 years old, what
mojhsa [17]

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).
