A. the air. All the other choices don't make sense.
Answer:
Cultural characteristics that are spread by mass media are examples of cultural diffusion.
Explanation:
A is correct because the mass media is the prime source that enables cultural diffusion, or rather it helps people connect better, understand each other better, and the people often chose to adopt some cultural trait that is from another place because they like it, not because they have to or are forced to.
B is not correct because the assimilation is a process where the people are either adopting culture because they need to, or because they are forced to.
C is not correct because the cultural appropriation represents using cultural traits from another culture, but it has happened in many ways throughout history, with the mass media being just the tip of the iceberg.
D is not correct because cultural accommodation happens when people adapt to their new surroundings, adopting cultural traits from the host culture for their social life, but keeping the cultural traits from their parent country at home.
Solar radiation is highly absorbed on land where the latitudes receive direct sunlight. Then scatters to the polar regions. The heat gathered between land and the reflection of heat from land to the atmosphere creates the net radiation surplus.
When solar radiation stretches to the polar regions it slowly loses heat and it becomes lesser than the heat reflected back to the atmosphere. This creates the net radiation loss.
