It would be easier to pull the hemispheres apart
1) when they are at sea level 2) if submerged several meters in water 3) if high above the clouds because 4) external pressure on the hemispheres is lessened. 5) water serves as a lubricant. 6) the atmosphere exerts a pressure of 105 N/m2 on both hemispheres.
