Explanation
The correct answer is (A) Burning of fossil fuels.
The burning of fossil fuels, such as coal, oil, and natural gas, releases greenhouse gases, particularly carbon dioxide (CO2), into the atmosphere. These greenhouse gases trap heat from the sun, leading to an increase in Earth's atmospheric temperatures, a phenomenon commonly known as global warming or climate change. Water pollution and soil erosion, while significant environmental concerns, do not directly contribute to the increase in atmospheric temperatures.
Key Points
• The global atmospheric temperature is maintained at a level that is suitable for life on Earth.
• This mainly achieved by the carbon dioxide (CO2) in the air and the clouds.
• The heat that enters the Earth's atmosphere is reflected back from the surface.
• This heat from the surface is trapped inside the atmosphere by the CO2.
• This phenomenon is known as 'greenhouse effect' and is vital for living beings.
• It is named after the 'greenhouse' which is a glass building that traps the heat inside to keep it warm.
• A glasshouse provides optimum temperature for plants to grow in cold climates.
