Why is the pointed arch seen in Gothic architecture structurally more stable than the rounded arch used earlier
it directed weight downward into the ground rather than outward onto the wall.
Answer:
It allowed for taller and lighter structures to be built.
Explanation:
With pointed arches, walls can be higher and thinner since the two sides of the walls are leaning on each other; for support and thus the weight are directed downwards, offering more stability. Also the Gothic style allowed for taller buildings as opposed to a rounded arch.
It also allowed for more flamboyant decoration as a result of the higher and thinner ceilings.
