Question

Name four contributory factors to climate change in world

Answer 1

Answer:

The name of four factors that contributes to climate change are as follows-

1. Deforestation- It is a process of cutting down trees, which results in the low absorption of CO₂ and less production of O₂ by plants and trees. This results in a global rise in temperature.
2. Burning of fossil fuels- The use of fossil fuels also is a threat to the increasing global climate because burning up fossil fuels releases carbon into the atmosphere which is a green house gas. A small increase in the concentration of carbon leads to a rise in the global temperature.
3. Amount of pollutants- The amount of pollutant present in the atmosphere, along with carbon and other gases, has the capacity to trap the incoming solar radiation, that increases the surface temperature on earth.
4. Green house gases- The green house gases are an important factor in rising the global surface temperature. These gases are CO₂, water vapor, CH₄, CFC. The increase in the amount of these gases can increase the rate of global warming.
