The Earth loses absorbed heat primarily by radiating long-wavelength infrared energy upward into space and through atmospheric convection and evaporation. This radiative cooling prevents thermal buildup and maintains stable global temperatures. Class 9 Science Chapter 13 Earth as a System: Energy, ...
Excess carbon dioxide intensifies the greenhouse effect, driving global warming, polar ice melt and ocean acidification that degrades marine life, outweighing any potential photosynthetic benefits to plants. Class 9 Science Exploration Chapter 13 Important Questions SQP from Class 9 Science Chapter 13 ...
Plants absorb atmospheric carbon dioxide through photosynthesis. Carbon returns to the air through plant and animal respiration, microbial decomposition of organic remains and the combustion of biomass and fossil fuels. Class 9 Science Exploration New Book All Chapter Solution Revise, Reflect, Refine ...
Deforestation reduces photosynthetic oxygen production while diminishing major terrestrial carbon sinks, elevating atmospheric carbon dioxide. It further accelerates severe topsoil erosion, decreases transpiration rainfall and destroys wildlife biodiversity. Chapter 13 Earth as a System: Energy, Matter and Life Solutions Class 9 Science ...
