WORLD HISTORY

Detailed explanation-1: -The Roman arch was the foundation of Rome’s architectural mastery and massive expanse of building projects across the ancient world. It allowed the Romans to make bigger buildings, longer roads, and better aqueducts. The Roman arch is the ancestor of modern architecture.

Detailed explanation-2: -The volcanic ash reacted with the lime paste to create a durable mortar that was combined with fist-size chunks of bricks or volcanic rocks called tuff, and then packed into place to form structures like walls or vaults.

Detailed explanation-3: -They built massive aqueduct systems of brick and stone that brought water from the mountains into urban centers. Using the gravity feed principle allowed Roman engineers to transfer water in some aqueduct systems for as much as 40 to 50 miles (64 to 80 km).

Detailed explanation-4: -The Romans are known for their remarkable engineering feats, be they roads, bridges, tunnels, or their impressive aqueducts. Their constructions, many of them still standing, are a testament to their superior engineering skills and ingenuity.
