What type of feedback maintains stability in a system; i.e., what type of feedback keeps a system functioning properly?

__________ is the ratio of the image on a map to that of the real world.
Numerous devastating wildfires have occurred over the last decade. As the fires burned, they dried the wet shrubs and green wood around the fire, thus providing more fuel for combustion. The greater the fire, the greater the availability of fuel becomes, and thus more fire is possible. This pathway is an example of __________.

A system is any unordered, unrelated set of attributes that are not linked.
Understanding the size and shape of Earth is a primary goal of geodesy.
A meridian is a line that connects all points along the same latitude.
If a world map shows Greenland and South America to be about the same size (area), it is quite possibly a Mercator projection.
