The OLDEST seafloor is located?
A
Closest to the mid-ocean ridge
B
Farthest from the mid-ocean ridge
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The next oldest seafloor is found at the margins of the north Atlantic Ocean and the northwestern Pacific Ocean, as far as possible from the mid-ocean ridges where they were created. These parts of the seafloor are about 200 million years old.

Detailed explanation-2: -Seafloor is youngest at the mid-ocean ridges and becomes progressively older with distance from the ridge. The characteristics of the rocks and sediments change with distance from the ridge axis as seen in the Table below.

Detailed explanation-3: -The world’s oldest oceanic crust – around 340 million years old – lies at the bottom of the eastern Mediterranean Sea, according to a geologist in Israel.

Detailed explanation-4: -The youngest ocean floor is located on the mid-ocean ridge. Where is the oldest ocean floor located? The oldest ocean floor is located near the continents, next to a subduction zone. There are rocks on every continent that are 3 to 4 billion years old.

Detailed explanation-5: -The oldest patch of undisturbed oceanic crust on Earth may lie deep beneath the eastern Mediterranean Sea – and at about 340 million years old, it beats the previous record by more than 100 million years.
