Study Notes
Water Resources Review
-
Learning Targets: Students should be able to describe water distribution, identify water resources, explain how human activities impact water quality and availability, and suggest ways to conserve and protect water.
-
Water Distribution: Earth has more water than land due to being in the habitable zone, where liquid water exists. Earth's stable atmosphere and water cycle keep water covering most of the planet, supporting life.
-
Water Resources on Earth: There are five recognized oceans: Pacific, Atlantic, Indian, Arctic, and Southern. Freshwater constitutes about 2.5% of the Earth's surface water.
Water Distribution Breakdown
- Total Water on Earth: Approximately 35.2 trillion cubic kilometers
-
Freshwater: 3% of total water
- Ice caps and glaciers: 70% of freshwater
- Groundwater: 29.9% of freshwater
- Accessible freshwater: 1% of freshwater which includes -Lakes: 52% of accessible freshwater. -Water vapor: 8% of accessible freshwater. -Rivers:1% of accessible freshwater
Importance of Water
- Water Scarcity: Growing population leads to exceeding demands over what is available.
- Responsibility: Conserving and protecting water is the responsibility of all.
Categories of Water Use
- Agriculture: 85.27% of water use
- Domestic/Household: 7.48% of water use
- Industrial: 7.22% of water use
- Others: 0.03% of water use includes recreation, Aquaculture, and livestock.
Water Cycle
-
Hydrologic Cycle: The water cycle describes how water continuously moves. Key processes include:
- Evaporation
- Precipitation
- Condensation
- Transpiration
- Runoff
Water Management (Specific Examples Included)
- Groundwater: Groundwater fills empty spaces underground.
- Springs: When the water table meets the surface, natural groundwater flow is generated, creating springs.
- Hot Springs: When heated groundwater flows to the surface, it creates hot springs.
- Water Treatment Plants: Used to treat and reuse wastewater to improve water quality.
Philippine Clean Water Act of 2004 (RA 9275)
- Purpose: To protect bodies of water from land-based pollution
