<h2>Answer: D. Rayleigh wave
</h2>
Rayleigh waves are a type of surface acoustic wave that causes particles on the surface of solids to travel along an elliptical path in the vertical plane that contains the direction of wave propagation.
These waves include longitudinal (P wave) and transverse (S wave) movements whose amplitude decreases exponentially as the distance from the surface increases.
This means Rayleigh waves are generated by the interference between the P and S waves on the surface of the Earth.

Answer:
Geographer uses a globe to answer regional questions by studying its exact and relative position with the help of latitude and longitude.
Explanation:
- Globe is simply a scale model of earth.
- With the help of globe, scale factor, latitude, longitude and direction a geographer can easily describe any place in the world.
- Geographers use map to solve problems, make comparison and answer any regional or global question easily.
- A geographer has the good knowledge of: location, place, human-environment interaction, movement, and regions which makes them able to answer any regional level questions using a globe.
