Water and Soil Conservation
2

• Water covers most of the earths surface
• Our bodies are 90 water
• Potable water drinkable

3

• Freshwater flows from the land to ocean and has
  little or no salt
• Tidewater the water that flows up the mouth of a
  river as the ocean tide rises or comes in

4
Food Chain

• Bay and ocean --- Insects and shellfish
  ---people, animals, birds

5
Water Universal Solvent

• Causes things to
• -rust
• -corrode
• -decompose
• -dissolve

Purposes of water

1. Habitat for microorganisms
2. Carries life-supporting oxygen
3. Gathers and transports nutrients
4. Cleans and purifies
5. Neutralizes and removes waste

Land provides

• 1. Solid foundation
• 2. Nutrition and support for
• plants
• 3. Space for work
• and play
• 4. Heat and
• compression
• chamber
• Land erosion wearing away of soil due to wind
  water

8

• Deserts areas with continuous severe water
  shortage
• Precipitation rains, snow, sleet, and hail
• Evaporation change liquid to a vapor or gas

9

• Water table level below which soil is saturated
  or filled with water
• Springs water held below the water table may run
  out onto the surface in the form of this

10

• Free/Gravitational water water that drains out
  of the soil
• Capillary water the moisture that plant roots
  absorb from the free water
• Hygroscopic water water held too tightly for
  plant roots to absorb
• Plants will die if their roots cant get air
• -happens if the soil is saturated

11

• Save clean water
• Dispose of household products carefully
• Care for lawns, gardens, and farmland carefully
• Practice sensible
• pest control

12

• 5. Control water run-off
• 6. Control soil erosion
• 7. Avoid spilling gas, fuel, and oil
