The word "dome" is used here but the text does not specifically suggest that the covering was round—only that it covered them on all sides, however a dome is the most likely shape that would have be able to withstand the impact with the ground. From verse 9 that says "when they saw it" and verse 11 that says "shut us up in this prison", we can conclude that the dome had holes in its sides that were big enough to let in light and air but were too small to allow Adam and Eve to escape. Another conclusion would be that the holes were large but too high up for Adam and Eve to reach, however the former is more likely.
