Answer :
Final answer:
The correct option is b) Concrete and arches
Explanation:
Roman engineering relied heavily on the innovative use of concrete and arches, which facilitated the construction of large buildings and aqueducts. Unlike the Greeks who primarily used marble and limestone, the Romans developed a durable concrete formula using volcanic ash called pozzolana, which enabled them to build structures of immense size and complexity. The arch, another hallmark of Roman engineering, distributed weight effectively, allowing for the construction of sturdy bridges, aqueducts, and monumental structures like the Colosseum and the Pantheon. This combination of concrete and arches revolutionized construction methods, providing the Romans with the tools necessary to create lasting architectural marvels that still inspire awe and admiration today.
Final answer:
Roman engineering prowess was characterized by their innovative use of concrete, the true arch, and the construction of aqueducts. These features were instrumental in the creation of large buildings and complex structures like the Colosseum and the extensive network of aqueducts that supplied water to cities.
Explanation:
The feature of Roman engineering that helped them build large buildings and aqueducts was their mastery in using concrete, the true arch, and aqueducts. The Romans developed a special water-resistant cement that lined aqueducts, facilitating the transport of water from source to cities. Their ability to design true arches with wedge-shaped stones, known as voussoirs, and a central keystone, enabled them to transfer weight efficiently and span larger distances without the need for interior supports, which was a limitation of the post-and-lintel construction. This innovation allowed for the creation of vaults and domes that led to grand interior spaces, and the construction of taller and more complex structures.
Roman architects, whose names are largely unknown to us, were versatile individuals responsible for overseeing the entire construction process from design to completion. They built various types of buildings, ensuring durability and aesthetic grandeur. The Roman Colosseum and the network of aqueducts standing tall with their arched bridges are testaments to their engineering prowess.
