Explanation:

Identify the core question

The question asks to choose all examples of scientific evidence for seafloor spreading.

Evaluate the options

Using the Seafloor Spreading knowledge point:

• "the differences in ocean current temperatures": This is related to oceanography and climate, not geological evidence for seafloor spreading.
• "magnetic stripes of rock on the ocean floor": Using the Magnetic Reversals knowledge point, symmetrical magnetic striping on either side of a mid-ocean ridge provides direct evidence of new crust forming and recording Earth's magnetic reversals.
• "the presence of continents": This is a general geographic feature, not specific evidence for seafloor spreading.
• "a pattern of variations in age of different parts of the seafloor": Rocks are youngest near the ridge crest and get progressively older farther away, which directly supports seafloor spreading.
• "undersea rock formations": Specific formations like pillow lavas at mid-ocean ridges show that molten material has erupted repeatedly, serving as evidence.

Answer:

• the differences in ocean current temperatures
• magnetic stripes of rock on the ocean floor (Correct answer)
• the presence of continents
• a pattern of variations in ages of different parts of the seafloor (Correct answer)
• undersea rock formations (Correct answer)
