WebThe water cycle, in the simplest form, is evaporation, condensation, and precipitation. Evaporation: When the temperature raises high enough, the water particles begin to move faster and gain more kinetic energy. As they move faster, the particles spread out in all directions. This spreading converts the water into a gas, or water vapor.

WebA water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons. All of the electron pairs—shared and unshared—repel each other. WebThere is little information on the early history of Earth’s waters. However, fossils dated from the Precambrian some 3.3 billion years ago show that bacteria and cyanobacteria (blue-green algae) existed then, indicating the presence of water during that period.
