The leaning tower of Pisa is an example of an oblique cylinder and is considered a UNESCO world heritage site. The tower has a height of 184.6 ft, and a base
diameter of 50.8 ft.?
I need help please

The form of the tower is a combination structure. This is because the brick and cement make the structure a solid structure. Since the Leaning Tower Of Pisa is hollow, it is a shell structure.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
