Challenge Problems
Push your limits with advanced challenges
An earthquake occurs at a focus of 15 km below the surface. If seismic stations detect P-waves first at 5 seconds and S-waves afterwards at 10 seconds, calculate the time difference in travel and interpret what this tells us about the Earth’s layers.
💡 Hint: Consider speeds: P-waves travel faster than S-waves.
Explain how gravity anomalies can indicate the presence of different types of materials in the Earth's crust and mantle.
💡 Hint: Think about the principles of density and gravitational pull.
