Question

new ocean floor is always being created through areas called mid - ocean ridges. this oceanic lithosphere then moves outwards from the mid - ocean ridges towards the continents on opposite sides of the ocean. the oldest ocean floor is closest to the continents. the lithosphere is then subducted underneath the continents in areas called trenches. trenches allow the rock cycle to continue as the rock is melted back into magma. place the sections of the ocean floor in order from youngest to oldest. section select is the youngest, then section select and finally section select is the oldest.

Explanation:

Step1: Recall ocean - floor age concept

New ocean floor is created at mid - ocean ridges.

Step2: Analyze distance from mid - ocean ridge

Areas closer to mid - ocean ridge are younger.

Step3: Identify positions in the image

Section C is closest to mid - Atlantic Ridge, then B, then A.

Answer:

Section C is the youngest, then section B and finally section A is the oldest.
