Module 2:
Water Basics

Humanity and geology studies

Background

Water resources on our planet can only be understood within the context of the water cycle: there is only one total amount of water, and the same water continues to move through the different states of solid (ice), liquid (water), and gas (steam) in a repeated cycle on the Earth for all time. The sun is the “motor” of the water cycle. On the surface, water flows across the land and underground, settling eventually in rivers, ponds, lakes, and oceans. As the water is heated by the sun, it evaporates and enters the atmosphere in the form of steam to make clouds.

Thematic concepts

Water as a human right

On 28 July 2010, the United Nations General Assembly recognized the human right to water and sanitation and acknowledged that clean drinking water and sanitation are essential to all human rights. 

Solid, liquid, and gas

When steam in the atmosphere cools, it condenses and, depending on the climate and temperature, returns to the planet in the form of different types of precipitation such as rain, snow, sleet, and hail.

Groundwater

Liquid water found underground in the cracks and spaces in soil, sand, and rock, which is stored in and moves slowly through geologic formations of soil, sand, and rock called “aquifers.”
