Question

Question 11(Multiple Choice Worth 3 points) 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:

Option (2)

Explanation:

The mid-oceanic ridge is the region along which the sea floor spreading takes place. It forms a divergent plate boundary. Here, the magma forces to come out to the surface, by stretching and thinning the lithosphere. These magma as it comes out to the ocean floor along this mid-oceanic ridge, it immediately cools and form rocks that are basaltic in composition and lavas are formed. The Mid-Atlantic ridge is an example of mid-oceanic ridge.

According to the given condition, the solidification age at the Mid-Atlantic ridge is given. This indicates that the rocks that last crystallized 10,000 years ago at the Mid-Atlantic ridge are the youngest rocks.

Hence, the correct answer is option (2).

Answer 2

uhhh, I think 52, this is super old anyways.
