Question

Question 6(Multiple Choice Worth 3 points) B If solidification ages at the Mid-Atlantic Ridge are around 10,000 years old, what does this tell you about the Mid-Atlantic Ridge? The Mid-Atlantic Ridge began to produce oceanic crust 10,000 years ago. The youngest rocks in the Mid-Atlantic Ridge solidified 10,000 years ago. The Mid-Atlantic Ridge ceased producing oceanic crust 10,000 years ago. The rocks at the Mid-Atlantic Ridge recorded the magnetic fields 10,000 years ago. The rocks adjacent to the Mid-Atlantic Ridge are older than those further away from the ridge.

Answer 1

Answer: I just took the test and the answer is the youngest rocks in the Mid-Atlantic Ridge solidified 10,000 years ago. AKA the answer is B.

Answer 2

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).
