Which slope typically has heavier vegetation cover due to climate and soil differences?

1. East slopes

2. West slopes

3. North slopes

4. South slopes

The correct answer is: North slopes

The correct choice is North slopes, which typically have heavier vegetation cover due to their unique climate and soil characteristics. In many regions, especially in the Northern Hemisphere, north-facing slopes receive less direct sunlight compared to south-facing slopes. This reduced sunlight means cooler temperatures and higher moisture retention, creating a more favorable environment for lush vegetation to thrive. Additionally, north slopes often benefit from the accumulation of organic material and improved soil moisture due to less evaporation. These factors together lead to denser plant growth and a richer ecosystem. In contrast, other slopes, particularly south slopes, tend to be drier and warmer because they receive more direct sunlight, which can lead to sparser vegetation. East and west slopes can have variable vegetation coverage depending on local conditions, but generally don't consistently possess the same level of vegetation density as north slopes.
