  3. Solar Radiation • Almost all of the energy that drives the various systems, including the hydrologic system, found on the Earth originates from the sun

  4. Evaporation • As water is heated by the sun, it evaporates and rise as invisible vapour in the atmosphere.

  5. Transpiration • Water vapour is also emitted from plant leaves by a process called transpiration. Every day an actively growing plant transpires 5 to 10 times as much water as it can hold at once.

  6. Condensation • As water vapour rises, it cools and eventually condenses. These water particles then collect and form clouds

  7. Wind (transport) • Clouds move around the world, propelled by air currents.

  8. Precipitation • Precipitation in the form of rain, snow and hail comes from clouds.

  9. Runoff • Excessive rain or snowmelt can produce overland flow to creeks and ditches. Runoff is visible flow of water in rivers, creeks and lakes as the water stored in the basin drains out.

  10. Groundwater • Subterranean water is held in cracks and pore spaces. It can also be tapped by wells.

  11. Infiltration • When water falls on the ground as rain, hail or snow, it can soak into the ground – this process is called infiltration
