migration rates,birth rates and death rates are all ways to measure changes in the population?
Answer:
Knowing that the temperature at sea level (0 m) is 20 ° C, we will calculate the air temperature at. The altitude of 3500m.
According to the vertical thermal gradient, the air temperature decreases by 6 ° C at 1000m alt.
1000 m .... 14 ° C (20-6 = 14)
2000 m .... 8 ° C (14-6 = 8)
3000 m ... 2 ° C (8-6 = 2)
3500 m .... - 1 ° C (2-3 = -1

Answer:
Listed
Explanation:
Five common energy sources are
1. Coal and Petroleum
2. Nuclear energy
3. Geothermal power
4. Solar
5. Wind
conservation of energy is very important in current situation of energy crisis. Efficient utilization of energy sources must be one of the top priority of nations.
1. Procurement of alternate sources of energies to reduce dependence on convectional sources of energies.
2.vehicle running on electric and hydrogen fuels should developed so that sources of coal and petroleum are conserved.
3. Production of solar and wind energies should be on large scale so that their cost become cheaper and available for common people
