North-Facing Slopes in Mountainous Areas of Western North America Would

Question

North-facing slopes in mountainous areas of western North America would be expected to ________.
A) receive more sunlight than similar southern exposures
B) be warmer and drier than comparable southern-exposed slopes
C) support biological communities similar to those found at lower elevations on similar south-facing slopes
D) support biological communities similar to those found at higher elevations on similar south-facing slopes

Accepted Answer

North-facing slopes in mountainous areas of western North America receive less direct sunlight than south-facing slopes, leading to cooler and moister conditions. These conditions are more similar to those found at higher elevations, thus supporting similar biological communities.
