which is one piece of evidence of seafloor spreading?\n○ fossil material\n○ continent material\n○ drilled core samples\n○ ocean water samples

Answer

Brief Explanations:

Drilled core samples from the ocean - floor can show the age and magnetic patterns of rocks. These patterns support the theory of seafloor spreading as new rock is formed at mid - ocean ridges and moves outward. Fossil material and continent material are not direct evidence for seafloor spreading. Ocean water samples do not provide evidence for the process of seafloor spreading.

Answer:

drilled core samples
