- Q13Which hazard of earthquakes is described as the collapse of buildings caused by earthquake vibrating water-saturated fill or unconsolidated soil?LiquefactionGround RuptureGround ShakingTsunami10s
- Q14What kinds of materials amplify ground shaking?Hard rocksRocks with a foliationMetamorphosed sedimentary rocksSoft soils and sediments10s
- Q15Why did the distribution of earthquakes and volcanoes help confirm plate tectonic theory?Earthquakes and volcanoes were different along with different types of boundaries.Neither earthquakes nor volcanoes had been studied much before plate tectonics.Both earthquakes and volcanoes were distributed randomly.Earthquakes and volcanoes were the same along all of the plate boundaries.10s
