Understanding Earth’s Water Cycle and Climate Regions

Earth’s Water and Climate

The Water Cycle

Groundwater contained within a reservoir rock is called an aquifer. Inland waters play a crucial role in the hydrological cycle. Their ultimate destination is typically the sea. The cycle involves evaporation from the sea to the atmosphere, condensation and precipitation from the atmosphere to the lithosphere, evaporation and transpiration from the soil to the atmosphere, and finally, precipitation back to the sea or land.

The water balance model accounts

Urban Development and Evolution: From Pre-Industrial to Contemporary Cities

1. Urban Population Dynamics

1.1. The Rise of Urban Populations

Traditional societies were primarily rural, while modern society is fundamentally urban. In 1900, only 10% of the global population resided in cities. By 2003, this figure reached 48%, and it is projected to hit 61% by 2030. Megacities like Tokyo, Mexico City, New York, São Paulo, and Mumbai continue to expand, with urban populations, particularly in Asia and Africa, expected to increase significantly.

Evolution of Human Societies: From Paleolithic to States

Agricultural Society (10,000 years ago)

Hunting led to severe exhaustion and population increase. This forced the use of other resources. Societies became sedentary, leading to a new economy based on asset accumulation and redistribution. Surpluses were stored for the first time. Competitive distributions among leaders and followers emerged, establishing a social hierarchy.

Emergence of the State

Features:

  • Centralized power
  • Highly stratified society (military, religious, administrative, artisans)
  • Clear
