Class 76: Wednesday, 1/20/2021
Warm Up:  
A positive feedback loop occurs when an effect increases the cause that created the effect.  A positive feedback loop causes change and instability.
Negative feedback occurs when an effect decreases the cause that created the effect.  Negative feedback results in stability.

1.  Which of these is an example of positive feedback, and which is negative?

A)  A room gets hotter.  The thermostat senses this and turns off the heater, causing the room to get cooler.
B)  The Earth gets hotter.  This melts snow.  As the snow disappears, the darker ground below is better able to absorb sunlight, causing the Earth to get hotter.

2.  Can you think of another example of positive or negative feedback
Air conditioning/refrigerants, methane, permafrost, and swamps

Warm Up: 
In 1904 scientists discovered that the Earth's magnetic field has reversed in the past.  At times in the past, our Magnetic North Pole has been the South Magnetic Pole. 

Magnetic materials in magma align with the Earth's magnetic field, but when the magma hardens to form rock, those magnetic materials are stuck that way forever.  In the 1960s, scientists studying the ocean crust near the Mid-Atlantic Ridge discovered the pattern of rocks shown in the diagram on the right.  The alternating bands of crust have opposite magnetic directions, and they make a symmetric pattern on opposite sides of the Mid-Atlantic Ridge.

What do you think the scientists concluded from this discovery?
