Push factors occur where someone is currently living and make continuing to live there less attractive. A push factor could be political unrest, a lack of job opportunities, or overcrowding. Pull factors occur in a potential destination and make it an attractive place to migrate to. A pull factor could be better job opportunities or having relatives or friends who have already moved to this location.Explanation:

In other words, the density of the material on top, has to be in balance with the density of the material below it, thus to not have any uplift or sinking occurring between them.

Answer:

The buoyant force from the asthenosphere and gravity
