Answer:
polar and tropical air masses
differences in latitude
varied elevations throughout the region
Step-by-step explanation:
polar and tropical air masses
Polar air typically cold while tropical air masses typically warm/hot. Both of these air will influence the average ocean temperate within East Asian region, influencing the type of fish that can live in their ocean,.
differences in latitude
Latitude will influence how far a region is located from Equator. The Asian region that's closest to the equator tend to have better soils and sun acquisition that suitable for agriculture.
varied elevations throughout the region
Elevations generally affect the pressure within the region. When pressure decreases, air molecules spread and it will lower the average temperature in the region.
