a. found at the mid-ocean ridges.

b. beneath the least amount of sediment.

c. older than the oldest continental crust.

d. less than 180 million years old.

Answer 1

The oldest oceanic crust is found at the mid-ocean ridges. Thus, option "A" is correct.

How old is the youngest oceanic crust?

The ocean crust is about younger than 200 million years (for example, smaller than 5% of the age of the earth).

The crust is most naive (still being created by volcanic eruptions) along the axis of the mid-ocean ridges and increases in age down the sides of the mid-ocean rises and out onto the more serious basin floors.

Thus, option "A" is correct.
