Question: 1 assuming that the south atlantic began forming 135 million...

Question details

1. Assuming that the South Atlantic began forming 135 million years ago, and has been spreading steadily ever since, calculate the full seafloor spreading rate in cm/yr at the equator near Romanche Fracture zone (~3,500 km away from Africa).

2. Assuming that the South Atlantic began forming 135 million years ago, and has been spreading steadily ever since, calculate the full seafloor spreading rate in cm/yr at Buenos Aires (35º S latitude) (4,000 km away from the Mid-Atlantic Ridge).

3. Are the full spreading rates that you calculated above slow (1-5 cm/yr), intermediate (5-9 cm/yr), or fast (>9 cm/yr)?
