How do rocks along the central valley of the mid-ocean ridge provide evidence of sea- floor spreading?
Rocks along the central valley of the mid-ocean ridge display symmetrical patterns of magnetic striping where new oceanic crust is formed. This occurs as magma is extruded along the ridge, creating a record of Earth's changing magnetic field over time. The alternating magnetic polarity of these rocks provides concrete evidence for sea-floor spreading and the movement of tectonic plates.

How do rocks along the central valley of the mid-ocean ridge provide evidence of the sea-floor spreading?
Rocks along the central valley of the mid-ocean ridge show a pattern of alternating polarity, indicating reversals in Earth's magnetic field. This pattern is caused by the cooling of magma at the ridge, locking in the magnetic orientation at the time of solidification. By studying the magnetic properties of these rocks, scientists can determine the rate of sea-floor spreading and the age of the oceanic crust.
What evidence suggests in indus valley cities were run by a strong central government?
A sophisticated and technologically advanced urban culture is evidence of an organized government in The Indus Valley Civilization
How is lava evidence of sea floor spreading?
Evidence shows that molten material erupts through this valley. The material then hardens to form the rock of the ocean floor.-Answered by Nadezda Dimsoski

How do rocks along the central valley of the mid ocean ridge provide evidence for sea floor spreading?
because the scientists found that the farther the rocks the older the rocks were. so the youngest rocks were found near the mid-ocean ridge. this showed that sea-floor spreading took place. +++ The primary evidence is "magnetic striping": remnant magnetising by the Earth's magnetic field of the iron compounds in the basalt forming the ocean floor. The magnetic traces are parallel to the spreading-ridges, and their polarity reflect the field's periodic reversal. The further from the ridge, the older the stripes. The rock is imprinted with the magnetism as it cools below a certain point in being eruped along the ridge.
