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.
Explanation:
Erosion by a river is caused by its capacity to curve out rocks and carry soil particles as sediments due to its erosion power. Rivers carve out rocks to form the pebbles you see in a river and also the rapids and cataracts.
A river contributes to the weathering of rocks such as limestone rocks. The water dissolves the calcium carbonate minerals in the limestone rocks making it brittle and easily crumble. Water also causes ferrous rocks to easily crumble due to turning of the iron minerals into rust.
rivers deposit their sediments when their velocity decreases. Deposits by rivers cause features like oxbow lakes and deltas that are observed at the mouth of rivers, where the slope gradient is very low.
