42
What are the three natural causes of climate change?
Volcanic eruptions Sun spots Changes in orbit
43
How do you volcanic eruptions cause climate change?
They release lots of greenhouse gases However, the ash reflects radiation back to space and cools the Earth
44
How do sun spots cause climate change?
Storms on the Sun that increased temperatures
45
How does changes in orbit cause climate change?
As the Earth orbit changes the Earth can change distance from the Sun and temperature
46
What are the two human causes of climate change?
Deforestation Agriculture
47
How does deforestation cause climate change?
Trees containing carbon from photosynthesis release it when they are cut down
48
How does agriculture cause climate change?
Farming of meat and dairy products produce methane Rice paddies produce greenhouse gases
