33
Q

Process of Salinization

A

Occurs when groundwater levels are close to the surface. in clay soils this may be within 3 m of the surface. in sand/silty soils it is less. capillary forces bring water to the surface where it is evaporated leaving behind any soluble salts that it is carrying, leading to the development of saline crusts.

34
Q

Process of Eturophication

A

the increased amounts of nitrogen and phosphorous that is carried in streams, lakes and groundwater causing nutrient enrichment. this leads to an increase in algal bloom which shades the water below, cutting off light levels for submerged plants which makes photosynthesis hard to carry out. Anoxia also occurs.

35
Q

Define Total fertility rate

A

The average number of babies a woman is expected to have in her life-time.
