Is an accurate description of the manner in which Maya civilization declined around AD 900?

The decline of the Maya civilization around AD 900 is attributed to a combination of factors, including severe droughts, overpopulation, agricultural exhaustion, and social unrest. These environmental and social stresses likely led to resource depletion and conflicts, resulting in the abandonment of major cities in the southern lowlands. While the civilization did not vanish entirely, many of its prominent city-states fell into decline, significantly altering the political and cultural landscape of the region.
