Question

Stacking heavy rocks atop each other, so that they

progressively overlap. The result is a rough dome ceiling. No mortar was used, and instead, smaller stones were inserted in crevices to lend stability.

Answer 1

The technique described is dry stone stacking, a method of stacking heavy rocks without mortar, using smaller stones in crevices for stability.

Step-by-step explanation:

Dry stone stacking is an ancient construction method that involves stacking heavy rocks without the use of mortar, relying on the precision of stone placement for stability. In this process, larger rocks are strategically positioned to form a dome-shaped ceiling, progressively overlapping to create a sturdy structure.

The absence of mortar is compensated by inserting smaller stones into crevices, enhancing stability and preventing the larger rocks from shifting. This method showcases the artistry and engineering skill required to balance and interlock stones effectively, forming a cohesive and durable structure. Dry stone stacking has been employed worldwide for various purposes, including building walls, bridges, and shelters, reflecting a sustainable and resilient construction technique that stands the test of time.

The success of this method lies in the meticulous arrangement of stones, relying on the principles of gravity and friction to achieve structural integrity without the need for additional binding materials.
