Answer: D
Explanation: The answer is D
Answer: The distrubance has a circular motion
Explanation:
Longitudinal wave- disturbance is parallel to the direction of the motion of the wave.
Transverse wave, disturbance is perpendicular to the direction of the motion of the wave.
Surface wave, the particles of the medium undergo circular motion. T
Is this a riddle cus it make no sense ._.
ITS B I’m pretty sure I had questions like this
The density gradient model most closely resembles the... urban model.
<h3>What is the density gradient model?</h3>
This model establishes particles are not equally distributed but there are some zones with more or fewer particles. Moreover, particles move from a higher concentration zone to a lower concentration zone.
<h3>What urban model is similar to the gradient model?</h3>
The density gradient model mostly resembles the demographic transition model that explains the density of demographic zones changes over time as more people move to the zone or people leave the zone. This is similar to density gradient because it shows density is not uniform and it evolves.
