Answer to Question 1

Cause and effect describes a situation where one factor causes another factor. Examples: Consuming excess energy causes weight gain; dropping a glass on a tile floor causes it to break; overcooking a food causes it to burn.
When two factors are correlated, a change in one is related to, but does not cause, a change in the other. Examples: The time spent watching TV is correlated with obesity in children. Driving at excess speeds is correlated with the likelihood of having an accident. The time that raw meat is left at room temperature is associated with the likelihood of it spoiling.
