Answers
Answer:
1) Strength of the sun. ...
Changes in the Earth's orbit. ...
Changes in the orientation of the Earth's axis of rotation. ...
Quantity of greenhouse gases in the atmosphere. ...
Carbon dioxide content of the oceans
2)Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.
3)Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gas- es, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.
Concept: Climate change.
To find:
1) Five factors that cause climate change.
2) Two effects of climate change on the environment.
3) Role of human beings in perpetuating climate change.
Answer:
1) Green house gases, rise in temperature, solar radiation, deforestation, automobiles and industries development are the factors that cause climate change.
2) Effects of climate change are drought and storm outbreak, melting of glaciers.
3) Human activities such as increased use of automobiles, cutting down of trees for building industries and factories, burning fossil fuels and over population highly effect the environment and leads to climate change.
