Question

In an earthquake-prone area, which earth material – igneous rock or sedimentary rock – would be better for constructing buildings? Explain your answer.

Answer 1

igneous rock would be best because igneous rock forms islands and sedimentary rock forms from sand and gravel like on the bottom of a river or lake and is not very stable

Answer 2

The correct answer is igneous rock.

The igneous rocks, in general are made up of the solidified magma. These rocks are made up of a strong solidified magma, which cools over the time and form a continuous massive structure. The sedimentary rocks are made up different rocks, which are combined under the pressure. During the stress of the earthquake, the sedimentary rock can break more easily as they are loosely packed than the igneous rocks, whereas, the igneous rock remain solid and shear less easily.
