how does the movement of tectonic plates create new mountains?

Answers

Answer:

For example, continental-continental convergence:

When continental plates collide, no subduction occurs as the plates are of similar buoyancy. However, the great amount of friction produced at the collision of plates causes the plates to fold and buckle, forming fold mountains.

It is friction between the moving plates as well as the build-up of sediments near the edges of the plates that causes mountains to be formed.

Answers

Answer:

it can kill you

Explanation:

Globalized culture no longer diffuses hierarchically as the Internet becomes more widely accessible and makes remote education, remote cultural activities, and news instantly available to everyone.

What is hierarchical diffusion?

A sort of cultural dissemination known as "hierarchical diffusion" takes place when powerful social structures promote the acceptance of particular new cultures or cultural elements. Hierarchical diffusion has some of the following traits: It affects all social classes, starting at the top.
