Water Sources

Water comes from two main sources: ground water and surface water
Ground water is water found beneath the earth's surface, often in aquifers
Water seeps through soil and rock layers to reach underground reservoirs
Borings or wells are used to access ground water
Water from bores may not be suitable for drinking without treatment

Surface Water

Surface water collects on the Earth's surface
Examples include rivers, lakes, dams, reservoirs, and waterholes
Rainwater collects to form surface water
Surface water may not be safe for drinking due to potential contaminants
Rainwater tanks collect surface water but may require treatment before consumption

Other Water Sources

Waterholes and rock holes are natural features where water collects
These provide crucial water supplies, particularly in arid regions
Springs naturally occur where water emerges from underground aquifers
The water flow in springs depends on factors like aquifer pressure, rainfall, and human water abstraction

River Features

A river is a large stream of water flowing over land
Rivers are categorized into upper, middle, and lower courses
The Upper Course: characterized by rapid flow, erosion, and canyon/valley formation
The Middle Course: characterized by gentler slopes, increased size, and formation of meanders and islands
The Lower Course: characterized by slow flow, deposition of eroded material, shaping of floodplains, and formation of deltas as it flows to the sea
