### water:

Rainwater
* Most rainwater carries water
  - conducts electricity
* Most rainwater contains materials
  - other materials
  - such materials
  - flows to the sea along rivers, but some is taken up by plant roots
  - is absorbed by the ground as fills the tiny spaces between soil particles
* Most rainwater passes through decay debris
  - plant debris
* Some rainwater accumulates in leaves.
* Some rainwater collects in clefts
* Some rainwater has energy
  - kinetic energy
  - infiltrates into the soil where living plants can take it up through their roots
* also soaks into the ground.
* becomes a weak carbonic acid from contact with carbon dioxide in the air
  - acid as it comes in contact with carbon dioxide, and eats away the softer rock
* can carry contaminants into our streams, rivers, lakes and ocean
  - the herbicides into the sewer systems
* can enter a building through leaks in walls, windows or the roof
  - and radionuclides can escape
  - leach the radioactivity in the soil shield to groundwater
* collects in ponds.
  - small amounts of dissolved minerals that have been blown into the air by winds
* drains away quickly because the soil is thin and porous
  - through the soil into the aquifers
* erodes the joints and bedding planes.
* falls through polluted air containing bacteria, smoke, smog and chemicals
  - to an impervious surface, and enters a catch basin
* fills pools and the water travels back down to the lake through tiers of carved rock.
* has few dissolved solids
  - impact
* is absorbed by the soil into the ground
  - another cause of flooded basement
* is better than irrigation water because it has less salt content
  - for the plants because it has less salt content
* is collected for bathing and dishwashing
  - in cisterns for irrigation
  - collected, filtered, purified and stored for drinking and washing
  - fresh water
  - most often soft water
* is naturally acidic, and corrosive to metal tanks and household plumbing
  - somewhat acidic because it dissolves carbon dioxide from the air
  - often acid and can erode limestone easily
  - pure when it drops from the heavens
  - simply the carrier that transports the pollutants to open waterways
  - slightly acidic because of the carbon dioxide dissolved in it
* is the chief article of diet at supper
  - one type of water which a city can secure by itself
  - prime source of freshwater on the Island, there being no rivers or streams
  - purest form of water
  - used for plants and in case of disasters
* leaches minerals out of the ash and into the soil.
* offers advantages in water quality for both irrigation and domestic use.
* passes through debris.
* penetrates plant tissue
* picks up particles and gases when it falls through the air.
* provides available water sources in many small island states in the Pacific
  - the other minerals
* seeps into waste rock piles and combines with oxygen and sulfides to form sulfuric acid
  - through cracks in the ground and through rocks
* sends mud down washes and creates flash floods that knock down berms and close roads.
* serves as source of distilled water.
* takes the quickest route to the sea and flows into rivers, streams, lakes and aquifers.
* trapped near foundations major source of moisture problems.

### water | rainwater:

Rainwater harvesting
* can eradicate poverty.
* is an everyman's water augmentation method
  - old tradition practiced in all parts of the world including Texas
* major source of drinking water for many people around the world.
