'Salinity'+Group

Salinity task card
 * ===The level of salts and minerals in the water is affected by the rising water table.===
 * ===Land clearing and irrigation (including domestic lawn watering) create high watertables and high salinity.===
 * ===Salinity affects agriculture.===

__**Type of Salinity**__
- Dryland salinity - Irrigation salinity (Irrigation salinity occurs in irrigated landscapes) - Urban salinity - Industrial salinity - River salinity **__Question 1: How is water under the ground effected by rainfall and irrigation?__** By salt reducing from the atmosphere. **__Question 2: What other things effect water under the ground?__** Things like the contamination (Like pollution and chemicals) and the weather (when it changes). **__Question 3: Own definition of 'Water Table'__**

**__Question 4: How does 'salinity' affect the environment?__**

**__Question 5: What is evapotranpiration?__** - Evapotranpiration is the process by which water tranferred from the land to the environmentby evaporation from the soil and other boundries and by transporation from plants. The trees help keep the water level low by sucking in the water but when you cut down the trees, the water level rises and the salt hits the surface. __** Question 7: What effect on irrigation have on soil, groundwater and rivers? **__
 * __ Question 6: How do trees prevent salinity from happening? __**
