Answer:
The growth in urban areas comes from both the increase in migration to the cities and the fertility of urban populations.The urbanization of the world is likely to slow population growth. It is also likely to concentrate some environmental effects geographically
Explanation:
Answer:T= 2898*10^-5K
Explanation:
wavelength = 10cm
Using Wien's Law
maximum wavelength= 2898*10^-6/temp(K)
thus T=2898*10^-6/10*10^-2
T= 2898*10^-5K
this is the maximum observed temperature of 10 cm wavelength black body
since this temperature is close to the diurnal equilibrium temperature, that's why it not get much colder.
