Final answer:
Earth-resting buildings vary in architectural features, with Gothic architecture displaying pointed arches and verticality, Romanesque architecture showing thick walls and round arches, and expressionist architecture using curved lines and domes.
Step-by-step explanation:
Earth-resting buildings are often characterized by architectural features that respond to their environment and the technology of their time. The examples given in the question relate to varying architectural styles and periods. For instance, Gothic architecture is known for its use of pointed arches, ribbed vaults, and flying buttresses, all achieving a more vertical emphasis and allowing for thinner walls and larger windows. In contrast, Romanesque architecture typically features thick walls, round arches, and large towers with alternating piers and columns. In some instances, vaults of stone or brick are evident, which later evolved into the pointed, ribbed arch characteristic of Gothic architecture.
Regarding expressionist architecture, curving lines and geometric forms, like domes, are common as well as structural emphasis on either horizontality or verticality. Lastly, the shape of roofs in long houses, similar to curving ship hulls, suggests that structural considerations often respond to environmental conditions such as the need for pitched roofs in areas with heavy snowfall.
