<span> The three zones of latitude :
i) Tropics till 23º.45 (between ± 23º.45)
ii) Temperate zone between 23º.45 to 66º.55. in both Hemispheres
iii) Polar Caps between 66º.55 to 90º, in both Hemispheres.
There are six major climate regions :
1. Tropical rain forests
2. Tropical grasslands (Savannah)
3. Deserts - China climate (from West to East)
4. Mediterranean climate - Temperate grasslands (Steppes, Prairie, Pampa, Veld, Downs)
5. Temperate rain forests - Taiga (from West to East)
6. Polar Ice caps
The matching is ---
1,2 : i)
3,4,5 : ii)
6 : iii) </span>
Answer:
animal wastes and fertilizers
Explanation:
The majority of the nitrates that are polluting the rivers come from the animal wastes and from the fertilizers used in the agriculture. The increased amounts of nitrates in the rivers causes eutrophication. This basically means that the water is becoming over-saturated with nutrients. This leads to the spreading out of the algae. As the algae spread out more and more, they cover the surface part of the water, so large portions of the rivers do not receive sunlight, which kills of the organisms that use photosynthesis. Further, the algae reduce the amount of oxygen in the water, often resulting in dying out of the fishes. It is a chain reaction that leads from one thing to another and the end result is devastating.
Green house effect is the trapping of heat by some gases ! mainly in our earth this is increasing due to CO2 !
1) wind power is a renewable resource, and will never run out (until the end of the world at least lol)
2) No harmful pollutions gases are produced
3) There are no fuel costs
4) Helps Negate the Greenhouse effect
etc. etc
hope this helps
