The wedge-shaped stone in an arch that causes the rocks to lock together is called a keystone. It is positioned at the top center of the arch and helps distribute the weight evenly across the stones, ensuring the stability and strength of the arch.
No. Silica is silicon dioxide, a chemical compound found in most rocks on Earth.
(16 stone) x (14 pounds per stone) / (2.20462 pounds per kg on earth) = 101.605 kg (rounded)
A damlike barrier made of earth and stone is known as an embankment dam. It is constructed by compacting layers of earth and stone to block the flow of water and create a reservoir behind it. Embankment dams are commonly used for water retention, flood control, and hydroelectric power generation.

It is a geode. Geodes form in gas bubbles in cooled porous lava flows. Groundwater provides the minerals that crystallize inside these hollow bubbles. Eventually erosion removes the lava rock that provided the mold that shaped the outside of the geode and then humans find them (and usually cut or crack them open to look at the crystals inside).
A geode is a hollow stone found on the earth that is lined on the inside with crystals.

It sounds like you are describing a geode, which is a rounded rock typically with a hollow cavity lined with crystals. Geodes are formed in sedimentary or volcanic rocks and can contain various types of minerals such as quartz, amethyst, or calcite.
It has nothing inside of it...it has no air and no one can live inside of the moon..It isn't a thin shell with nothing in it! It's just rock, stone and dust compacted by gravity.
A stone can be shaped with a stone grinder. A stone is placed in the grinder and then a person will maneuver the grinder to shape the stone the way they want it.
