A feedback loop has features that do NOT affect one another at all

• TRUE

• FALSE

A POSITIVE feedback loop amplifies/magnifies the effect

• TRUE

• FALSE

A NEGATIVE feedback loop amplifies/magnifies the effect

• TRUE

• FALSE

As temperatures warm, glaciers melt, this decreases albedo, which increases temperatures further... this is an example of a positive feedback loop

• TRUE

• FALSE

When you eat a meal the glucose level in your blood increases, your body then makes insulin, which removes excess glucose from your blood stream, bringing your glucose levels back down to a normal range... this is an example of a positive feedback loop

• FALSE
