Mass media is a significant force in modern culture, particularly in America. Sociologists refer to this as a mediated culture where media reflects and creates the culture. Communities and individuals are bombarded constantly with messages from a multitude of sources including TV, billboards, and magazines, to name a few. .”

Explanation: Europe and Asia have many things in common, the most obvious being the population distribution. These regions both have very urban and dense populations, although Europe is somewhat more urban. The populations live where they have access to resources, regardless of what the resource is. This connects to climate because the populations in each reason often choose to live in extreme temperatures, examples include Dubai, where temperatures regurlarly rise above 100, and Oslo, where it is not uncommon for the temperature to drop below 0.
Answer:
C. P waves move matter back and forth, in a direction parallel to the direction of the wave, while S waves move matter up and down, perpendicular to the direction of the wave.
Explanation:
P and S - waves are both called seismic waves. They are produced during deformation within the earth.
Usually, P or Primary waves have the fastest velocity and arrives at the seismic station first. Secondary, Shear or S-waves follows P-waves.
- P-waves are body waves that propagates within a body. They cause movement internally.
- Secondary waves are surface waves. They move on the surface of earth.
- One way to also distinguish between these two seismic waves is that, P-waves are longitudinal waves that travels parallel or longitudinally to the source.
- Secondary waves moves in an up and down motion pattern. They propagate transversely to their source.
Neptune is the eight planet from our Sun, one of the four gas giants, and one of the four outer planets in our Solar System. Since the "demotion" ofPluto by the IAU to the status of a dwarf planet – and/or Plutoid and Kuiper Belt Object (KBO) – Neptune is now considered to be the farthest planet in our Solar System.Sep 14,
