Step-by-step explanation:
The process by which an idea or innovation is transmitted from one individual or group to another across space is called cultural diffusion. This concept covers the spread of both material and nonmaterial cultural elements, like technology, language, and social practices, as they move through various populations and geographies over time.
Cultural diffusion occurs when ideas, values, or inventions spread within a culture or from one culture to another. This can take place through various means such as migration, trade, the influence of media, or the simple process of neighbors influencing one another. An example of this is the way different cuisines like Thai noodles or Italian gelato become popular in other parts of the world, or how the proliferation of social media platforms such can influence social movements globally.
The phenomenon of cultural diffusion enhances global interconnectedness by weaving together the values, technologies, and innovations of diverse cultures, leading to continuously evolving cultural landscapes.
