Question 7 of 10
7. Question
2 points
Which of the following statements regarding causes of climate change is/are correct?
1. Sunspots are dark and warmer patches on Sun whose increase in number leads to
warm and drier conditions on earth.
2. Variations in Earth’s orbital characteristics will change the amount of insolation on
