Answer:

B. is oldest at the mid-ocean ridge and youngest farthest from the ridge.

Step-by-step explanation:

The outermost part of the Earth's lithosphere, known as oceanic crust, is created at spreading centers on oceanic ridges that are found at divergent plate boundaries and is found beneath the oceans.

Let us analyze each choice.

A. The various methods that can be used to determine the age of the oceanic crust area radiometric dating of rock samples, analyzing fossil evidence, marine magnetic anomalies, or ocean depth. Hence this statement is TRUE.

B. The youngest crust is found near mid-ocean ridges and spreading zones, while the oldest crust is found farthest away from the ridge. Hence this statement is FALSE.

C. The newly formed rocks cool and begin to erode as the continental plates move away from the ridge, with sediment gradually building up on top of them. The youngest oceanic rocks are found near oceanic ridges, and they become progressively older as one moves away from the ridges. Hence this statement is TRUE.

D. Scientists discovered that as they moved away from the mid-ocean ridge, the crustal rock and sediments on the ocean floor grew older. The most recent and young rock was closest to the mid-ocean ridge. This data backed up the theory of seafloor spreading. Hence this statement is TRUE.

The question has asked the false statement, hence the required answer is B.
