Step-by-step explanation:
Empires go through cycles of rise and fall due to various factors such as natural resources, military power, climate change, disease, and warfare. These cycles can be observed in the Ancient Near East and Mesopotamia, where dominant cultures were repeatedly defeated and replaced by new conquerors. Despite the collapse of civilizations, new ones emerged from the remnants. The impact and influence of empires may change over time, as seen in Era 5 and Era 6 of World History. While some empires decline, new ones may rise in their place.
