I believe you mean mid-ocean ridge?
If so, true. 
A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics.
This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary. 
A mid-ocean ridge demarcates the boundary between two tectonic plates, and consequently is termed a divergent plate boundary.

To convert 0.0701 kilograms to milligrams, we must first figure out how many milligrams are in 1 kilogram.
1 kg (kilograms) = 1,000,000 mg (milligrams).
Since we have 0.0701 kg, we need to multiply 1,000,000 by 0.0701.
1,000,000 x 0.0701 = 70,100.
There are 70,100 mg in 0.0701 kg.
I hope this helps!
