The principal material used in its construction was stone. While documents agree that the stone was quarried locally I’ve never seen anything that was able to identify the type of stone. If you’re not familiar with stone construction it is very similar to brick masonry construction. The stone is shaped and put in place with …

Unless there is a water tank or booster pump you are going to loose about 0.4 psi per foot vertical. Given that most floors are about 10ft floor-to-floor that is 4 psi loss. So, if a first floor unit has 30 psi water pressure, the fourth floor unit has about 12 psi water pressure if …
Yes, though it might depend on the definition you’re using for levitation. We float a structure on a liquid like a boat, but I don’t think this is what you mean. Or in a gas like a balloon, but again this requires huge gas bags for buoyancy which will quickly limit your weight. Magnets and …

Short answer; temperature. Air is largely affected by temperature, which causes hotter air to rise above colder air. The sun is always heating a portion of the Earth, but not others, creating a hot spot which change the air temperature. Next major item is humidity or moisture content. the more water vapor present the heavier …

First, let’s assume you can’t change your roof in any significant way. You are looking for an element called a rain diverter. Basically, this is an ‘L’ shaped piece of flashing attached under the trailer edge of your roof tiles/shakes/slats. In most cases it only needs to be 1.5″ to 2″ high to catch the …
In the US the overwhelming amount of houses are constructed of light frame timber (2×4 or 2×6) then surfaced with either a cementous product like stucco or wood siding of some form. Larger homes and multi-family buildings used to be constructed of brick but modern larger homes and multi-families tend towards wood framing. Multi-families become …

In a vacuum they would stay together as long as there is no spin. In an atmosphere it would depend on the shape and placement of each object. A non-aerodynamic front object or overlapping second object would find the air pressure forcing the two apart.
Firstly, you don’t want organic material in your concrete. It will weaken and discolor your concrete. There are mixes that support organics, but they are expensive along with requiring special equipment and knowledge. That said, use about 60% gravel to 40% sand. This will get you close to a “well graded” mix. One part cement …
The resulting formation tells you the frequency, rate, and material of the specific eruptions. Basically, both versions are possible, but the forementioned determines which you get.
Since the atmosphere is rotating with us (largely due to inertia, friction, and gravity) the rotational component of the wind is canceled out. Usually the cause of wind is heat. This causes changes to pressure, densities and humidities. Thermodynamics pretty much takes over from there.
