Answer:

Spread away on both sides and get aligned with the magnetic properties of the earth.

Step-by-step explanation:

  • Harry Hess in his seafloor spreading theory has stated that the seafloor spreads at a continuous rate and that newer crust is fired by the recycling of the older crust form below and the upwelling of lavas or magmas at this mid-oceanic ridges this leads to the formation of the two distinct types of rocks with opposite magnetic properties.
  • Moving away from the rides we find the older rocks and moving closer we find newer rocks or slabs.
