Warming melts glaciers and sea ice in the cryosphere, raises sea levels and causes floods or droughts in the hydrosphere and triggers habitat destruction and species loss in the biosphere. Chapter 13 Earth as a System: Energy, Matter and Life Solutions Class ...
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 ...
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 ...
The troposphere hosts weather phenomena. It is heated from below by the Earth’s surface, creating vertical temperature drops and strong convection currents that cause warm air to rise, condense and generate storms. Class 9 Science Chapter 13 Earth as a System: ...
