4. What is a natural arch and how does it form?A natural arch is a curved rock formation that looks like a bridge. It forms when water and wind slowly wear away cracks in sandstone or limestone, making the middle part thin until it breaks and leaves an arch.
5. Why do arches help buildings hold heavy loads?Arches spread the weight of a roof or bridge along their curve, pushing the force down into the walls or pillars. This compression makes arches very strong and able to support more weight than flat beams.

Differential Weathering: The process where rocks erode at different rates due to variations in composition, structure, and exposure.
Voussoir Arch: An arch constructed from wedge-shaped stones or bricks (voussoirs) that lock together.
Catenary Curve: The curve formed by a hanging chain or cable supported at its ends, which is also the ideal shape for an arch under uniform load.
