Question

Which evidence causes most scientists to believe that seafloor

spreading occurs at the mid-Atlantic Ridge?
А
Oceanic crust is oldest at the ridge.
B
Large sedimentary folds exist in the mantle near the ridge.
Oceanic crust on both sides of the ridge is less dense than
continental crust.
D
Oceanic crust on both sides of the ridge shows matching
patterns of reversed and normal magnetic polarity.

Answer 1

Oceanic crusts on both sides of the ridge shows matching patterns of reversed and normal magnetic polarity.

Step-by-step explanation:

Mid-Atlantic Ridge is a collection of mountains that settle at the bottom of the ocean. These mountains are the result of the movement of the plates. The breakdown of these mountains was very important to give truth to the theory that defended the existence of the expansion of the ocean floor and continental drift. That's because by looking at the mid-Atlantic Ridge, scientists were able to see that the oceanic crusts on both sides of the mid-Atlantic Ridge had patterns corresponding to normal and reverse magnetic polarity. This was the basis for perceiving the movement of the ocean's bottom in random directions.
