Physics. The Earth's crust is made of two basic kinds of rock: SiAl and SiMa (named after the most prevalent elements in them: silicon-aluminium and silicon-magnesium). SiAl rocks, like feldspar, are less dense than SiMa rocks (like basalt) and tend to "float" on them. The continents are mainly SiAl.
Africa and Asia
Antarctica and Oceania are the two continents that do not have any of the top most popular countries in the world in terms of population, economy, or global influence.
evolutionary forces is most likely to decrease variation between populations
Africa and Asia are two continents that have experienced the most conflict due to diverse factors such as political instability, ethnic tensions, and resource competition. Countries within these continents face ongoing conflicts that have had significant human and economic consequences.
decreases genetic difference between two populations
Because it is large.
