6. where do P waves travel the fastest?a. mantleb. lower mantlec. cored. crust |
|
Answer» Because the earth's mantle becomes more rigid and compressible as the DEPTH below the asthenosphere INCREASES, P-waves travel faster as they GO deeper in the mantle. The density of the mantle also increases with depth below the asthenosphere. The higher density reduces the speed of seismic waves.
hence,your answer is option a.mantle mark my answer as brainliest answer and follow me....bye |
