What factor most directly impacts water availability in New Mexico?

The choice regarding seasonal weather patterns is correct because they directly affect precipitation levels in New Mexico, which is a crucial determinant of water availability in the region. New Mexico experiences a semi-arid climate with distinct wet and dry seasons. The summer monsoon season, which typically lasts from July to September, brings much-needed rainfall, while the winter months may see less precipitation and snowfall.

This fluctuating nature of seasonal weather patterns leads to variability in water supply, influencing not only natural ecosystems but also agricultural practices and urban water management. In turn, water availability can shape the overall socio-economic landscape, making understanding these seasonal shifts vital for resource planning and sustainability efforts in New Mexico.

The other factors, while relevant to the discussion of water resources, do not have as immediate an influence on water availability. Population density impacts demand for water but not the supply directly. Altitude variations can affect localized climates and moisture retention to some extent, but do not systematically dictate water availability across the state. Soil types are important for water retention and plant growth but also do not independently control the broader availability of water resources.
