Answer:
1. carbon dioxide when burned.
2 it traps carbon emissions traps heat in the atmosphere.
Explanation:
Fossil fuels produce large quantities of carbon dioxide when burned. Carbon emissions trap heat in the atmosphere and lead to climate change. In the United States, the burning of fossil fuels, particularly for the power and transportation sectors, accounts for about three-quarters of our carbon emissions.

Answer:
MULTISYSTEM FAILURE DUE TO ADVANCED AGE
Explanation:
it is also known as AGE OF RECIDING PANDEMIC . an increase in average life expectancy from about 30 years to about 50 years of age
Answer: Radio waves has the longest wavelength and Gamma rays has the shortage wavelength.
When wavelength increase and frequency decrease it is related to the energy of each type of radiation.
Explanation: The wavelength of Gamma rays is less than 10 pico meter and energy of Gamma rays is greater than 100kev while the wavelength of radiowaves is 100m to 100km and energy is 100ev to 100kev.
Energy is inversely proportional to wavelength so Gamma rays which have shortage wavelength will have highest energy and radio waves which have longest wavelength will have minimum energy
E=hc/wavelength
Following enlisted are the answers for the above mentioned question.
Explanation:
1. Population pyramids is graphical representation of data which enables oneself to distinguish and have a clear picture in minds about the ratio of population densities keeping any one parameter as constant. Population pyramids could be used to analyze data in many different scales on the basis of gender,age groups, race etc. Examples-having a record of no. of individuals in different age groups in India.
2. Generally, there are 3 types of population pyramid on the basis of shapes of the pyramid. Those are;
- Expansive
- Constrictive
- Stable
Siting an example of age-sex pyramids,
In case of the Expansive, population pyramids show that the populations that have a larger number of persons in young age groups. The shape obtained hence is usually with high fertility rates with lower death rates
Then comes, Constrictive population pyramids. These are named so since they are constricted at the bottom. They undue a low percent of young people as compared with other age groups. These type of pyramids show decreasing birth rates.
And at last, Stationary also called as stable population pyramids are the ones which depicts almost equal proportion of the population in each of the all age groups. There is not a decrease or increase in population; it is stable.
