<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: A)is greater near the source than near the mouth
Explanation: A stream is a small river; a large creek; a body of moving water confined by banks.
Gradient is an area of ground that tends evenly upward or downward.
A stream gradient can be defined as an area of water that that tends evenly upward or downward of the stream and it is measured by the difference in elevation between two points on a stream divided by the distance between the two points that the water actually flows.
The gradient influences the speed in respect to time of the stream. The steeper the gradient, the higher will be the speed of the of the flow.
