The map includes handwritten annotations. What do the annotations 'возвышенность' and 'изменчивость' likely refer to in the context of a world map, and where are they placed?

Map Annotations Interpretation

• The annotation 'возвышенность' (elevation/highlands) is written near the North Pole in both hemispheres, suggesting areas of high altitude or elevated terrain in polar regions, possibly referring to ice sheets or landmasses.
• The annotation 'изменчивость' (variability/changeability) is written near the Antarctic Circle in the Southern Hemisphere. In a geographical context, this might refer to the highly variable conditions of the Antarctic region, such as fluctuating ice cover, weather patterns, or even geological changes.
