Negative correlation, for two reasons.
1. People do not like to live in very cold places (think of the population near the Poles).
2. Population centres are hot spots due to man-made structures and activities. Buildings and roads absorb and retain heat more than nature. This micro-climate results in less snowfall (it melts before settling).

Correlation is a measure of the degree of agreement in the changes (variances) in two or more variables. In the case of two variables, if one of them increases by the same amount for a unit increase in the other, then the correlation coefficient is +1. If one of them decreases by the same amount for a unit increase in the other, then the correlation coefficient is -1. Lesser agreement results in an intermediate value. Regression involves estimating or quantifying this relationship. It is very important to remember that correlation and regression measure only the linear relationship between variables. A symmetrical relationshup, for example, y = x2 between values of x with equal magnitudes (-a < x < a), has a correlation coefficient of 0, and the regression line will be a horizontal line. Also, a relationship found using correlation or regression need not be causal.

The amount of snowfall is considered continuous because it can take on any value within a range and is not limited to specific, separate values. Snowfall can vary in depth and intensity, allowing for fractional measurements, such as 2.5 inches or 3.7 centimeters. In contrast, discrete data involves distinct, separate values, which does not apply to snowfall measurements.
There isn't any correlation between gathering wealth and IQ. Many factors are involved on becoming rich and keeping themselves rich. If it was true, IQ and wealth involved, rich men would not lose their wealth never. Desire of success and power leads many persons with a medium IQ to become rich.
what kind of correlation would you expect to find between a city's annual and the size of its population

There is obviously a correlation between population numbers and the amount of fuels used. Many of which release CO2 into the atmosphere. CO2, after water vapour, being the main contributor to the greenhouse effect. The exact amount of change caused by over population is very difficult to calculate.
Yes
A Pearson correlation measures the strength and direction of a linear relationship between two continuous variables, ranging from -1 (perfect negative correlation) to 1 (perfect positive correlation). An example could be studying the correlation between the amount of rainfall and crop yield in agricultural research to understand how variations in rainfall affect crop productivity.
This relationship is called the correlation between the amount of drivers education students have and the number of accidents they have. A positive correlation indicates that more education leads to fewer accidents, while a negative correlation would suggest the opposite.
There has been no definitive evidence that genetic modification of wheat causes an increase in celiac disease. However, there is a correlation between celiac disease and the amount of wheat ingested in a population.

The correlation between the amount of neurons and intelligence found in the frontal lobe of the brain is option C: .45. This suggests a moderate positive relationship where an increase in the amount of neurons is associated with higher intelligence levels.
