A research team is studying the velocity of seismic waves in various types of rock.Using explosives, they create small explosions to study how fast the energy waves will travel.Using the velocity data below, infer which rocks are higher in density and which are lower in density.Which rock or rocks have the highest density?
Rock A: 7 km/s
Rock B: 5.9 km/s
Rock C: 7.2 km/s
Rock D: 6.1 km/s
Rock E: 6.25 km/s
A)Rock C
B)Rocks B & D
C)Rocks B, D, & E
D)Rocks A & C
