I know this because I had the same questions on my quiz and I got them right. Also there is another question just like this asking "According to the model, which two points on Earth are experiencing summer?" and the correct answer for that question is A and C!
Weight is the downward pull on an object due to gravity.
For example, the moon has less gravity than Earth so we would weigh less on the moon. Our Mass and volume always stay the same but our weight could change.
