Complete the concept map :[Concept map: ‘Factors affecting environment’ divides into ‘Natural factors’ and ‘Manmade factors’, each with a box below it beginning ‘Ex........’]

Answer: Natural factors — e.g. rainfall, temperature, soil erosion, volcanic eruption, earthquake. Manmade factors — e.g. deforestation, pollution, industrialisation, urbanisation, use of plastic.

Natural factors are the changes brought about by nature itself, such as heavy rain, drought, storms, landslides and earthquakes. Manmade factors are caused by human activities, such as cutting of trees, burning of fossil fuels, release of sewage and industrial waste, and excessive use of fertilisers and pesticides; these disturb the balance of the environment much faster.
