Detailed explanation-1: -A negative correlation is a relationship between two variables in which an increase in one variable is associated with a decrease in the other. An example of a negative correlation would be the height above sea level and temperature.

Detailed explanation-2: -For each individual campsite, you have two measures: elevation and temperature. When you compare these two variables across your sample with a correlation, you can find a linear relationship: as elevation increases, the temperature drops. They are negatively correlated.

Detailed explanation-3: -Temperature normally decreases as elevation or height increases, making locations at higher elevations colder. For every 100-meter increase in elevation, the average temperature decreases by 0.7°C.

Detailed explanation-4: -On average the rate of temperature increase was significantly higher at low compared to high elevation (0.49 ± 0.12 and 0.27 ± 0.15 °C decade−1, respectively). A significant negative correlation was found between the elevation and the observed rate of change in air temperature over the last 35 years (figure 3).
