térdiffúzió

Térdiffúzió, also known as spatial diffusion, is a concept used in various fields to describe the process by which something spreads through space. This can refer to the movement of physical substances, information, ideas, or behaviors. In physics, térdiffúzió is often associated with the random motion of particles, leading to a net movement from an area of higher concentration to an area of lower concentration. This process is governed by Fick's laws.

In social sciences, térdiffúzió describes how innovations, cultural practices, or opinions propagate through a population or across geographical regions. This spread can occur through direct contact, media, or other communication channels. The rate and pattern of térdiffúzió are influenced by factors such as the nature of the item being diffused, the characteristics of the adopters, and the communication networks involved. For instance, new technologies or fashion trends often exhibit spatial diffusion patterns.

In geography, térdiffúzió is crucial for understanding the distribution and spread of phenomena across landscapes. This can include the diffusion of agricultural techniques, the spread of diseases, or the urbanization process. Geographers analyze different types of diffusion, such as contagious diffusion, where spread is from hearth to nearby places, and hierarchical diffusion, where it moves from larger centers to smaller ones. The study of térdiffúzió helps explain patterns of human activity and environmental change.
