Select the correct answer. While conducting a groundwater survey, scientists detected seismic waves at two different locations. These two locations happened to be the
same distance from the epicenter of an earthquake. However, the scientists noticed that they detected the waves at the first location before the
second location
The material between the epicenter and the first location was solld rock. The material between the epicenter and the second location was ocean
water.
Which statement explains why the waves were sensed at the first location sooner than at the second location?
