Q

Typically used in warmer climates, this method utilizes natural bodies of water such
as lagoons, allowing wastewater to pass through for a set period before being retained
for two to three weeks.

A

Oxidation Ponds

18
Q

The aim of _________ wastewater treatment is to raise the quality of water to domestic
and industrial standards, or to meet specific requirements around the safe discharge
of water. In the case of water treated by municipalities, tertiary treatment also
involves the removal of pathogens, which ensures that water is safe for drinking
purposes.

A

tertiary

19

21
Q

Grazing animals are animals that live on large areas of
grassland. They wander over the area and eat grasses and shrubs.

A

Overgrazing animals

22
Q

another practice that can greatly increase the
rate of erosion in a region

A

Deforestation

23
Q

major contributors to erosion, especially on a local level.
Many mining techniques involve shifting large amounts of earth, such as strip mining
or mountaintop removal.

A

mining operations

24
Q

•Involves removal of plants which cause more exposure to air and water and
speed up the process of chemical weathering.

A

Strip and open pit mining

25
Q

Urban and suburban development can also
exacerbate erosion, especially if the developers ignore the natural state of the land.

A

Development Expansion

26
Q

like driving vehicles off-road or hiking - Humans also
cause erosion through recreational activities, like hiking and riding off-road vehicles.

A

Recreational Activities

27
Q

the capacity of a soil to function for specific land uses or within
ecosystem boundaries.

sewage water are human feces and animal wastes like animal dung

A

organic waste water

38
Q

evidently different from residential, commercial, and industrial liquid
wastes, stormwater is still a kind of wastewater because it can be contaminated with
different pollutants that come from our surroundings.

A

Stormwater
