The topside should be the strongest because it is has the sharpest curvature. The topside is more domed shaped than the sides, so the topside is stronger.

The silverside is tougher than the topside just because of where it is cut from. The silverside is cut from the back of the thigh.

The topside watch will be charged with the comings and goings on the topside of the submarine (called a boat by those who sail on them) when the boat is tied to a pier or tender. There may be an officer of the deck there on some occasions, but when the boat is lying along side a tender or the dock of a submarine or naval base, security is such that the topside watch will be the lone crew member on the deck.

the ionosphere extends from around 50 km altitude to about 1000 km,

Within this range are the the various regions that make it up; D, E, F1, F2 and the topside, with the D region closest to us and the topside farthest from us, and in that order.

the topside can also extend to about 2000km in some part of the earth.

Most of the chlorophyll is on the topside of the leaf because that is the part of the leaf that receives the most sunlight.

Any plant that didn't follow that pattern would be crowded out by the other, more successful, plants.
