Which of the following are examples of a negative feedback loops? (level 1)

1

(level 1)
The image above is an example of a...

A positive feedback loop

A negative feedback loop

2

Which statement about carbon dioxide is true? (level 2)

Global temperatures depend on the total amount of carbon on earth

Oceans absorb carbon dioxide much faster than humans add it to the atmosphere.

Human actions have little effect on the amount of carbon in circulation.

Burning fossil fuels increases atmospheric carbon dioxide levels

2

The main influence on Earth’s climate over geologic time is: (level 2)

Plate tectonics

Human activity

The water cycle

Milankovitch cycles

2

Which is an example of a positive feedback loop? (level 2)

Decreasing temperature ➜increase in ice cover ➜increase in reflection of sunlight ➜decrease in temperature

Decreasing temperature ➜decrease in plant cover ➜decrease in absorption of carbon dioxide ➜increase in temperature

Increasing temperature ➜increase in plant cover ➜increase in absorption of carbon dioxide ➜decrease in temperature

Increasing temperature ➜increase in weathering and erosion ➜increase in marine shell growth ➜decrease in temperature
