Question

the farther away from a mid-ocean ridge the crust is, the ________ it is.

older
fresher
younger
hotter

Explanation:

Analyze seafloor spreading at mid-ocean ridges

New oceanic crust is continuously formed at mid-ocean ridges through volcanic activity. As magma rises and cools, it pushes older crust outward away from the ridge crest.

Determine age relationship with distance

Because new crust is constantly created at the ridge center, the crust closest to the ridge is the youngest. Consequently, as you move farther away from the mid-ocean ridge, the oceanic crust becomes progressively older.

Answer:

• older (Correct answer)
• fresher
• younger
• hotter
