Question

base your answers to questions 24 and 25 on the graph below, which shows changes in the suns magnetic activity and changes in the number of sunspots over a period of approximately 100 years. sunspots are dark, cooler areas within the suns photosphere that can be seen from earth. 24) which graph best represents the relationship between the number of sunspots and the amount of magnetic activity in the sun? (1) graph with amount of magnetic activity on y - axis and number of sunspots on x - axis with a positive - sloped line (2) graph with amount of magnetic activity on y - axis and number of sunspots on x - axis with a horizontal line (3) graph with amount of magnetic activity on y - axis and number of sunspots on x - axis with a vertical line (4) graph with amount of magnetic activity on y - axis and number of sunspots on x - axis with a negative - sloped line 25) the graph indicates that years having the greatest number of sunspots occur (1) in a cyclic pattern, repeating approximately every 6 years (2) randomly and unpredictably (3) precisely at the beginning of each decade (4) in a cyclic pattern, repeating approximately every 11 years

Explanation:

Step1: Analyze the main - graph

By observing the main graph showing solar sunspots and magnetic activity over 100 years, we can see that when the number of sunspots is high, the magnetic activity is also high. This indicates a positive - correlation relationship.

Step2: Match with options

For question 24, option (1) shows a positive - correlation where as the number of sunspots increases, the amount of magnetic activity increases, which is consistent with the main graph.
For question 25, by observing the peaks of the sunspots curve in the main graph, we can see that the years with the greatest number of sunspots occur in a cyclic pattern, repeating approximately every 11 years.

Answer:

1. (1) A graph with a positive - slope representing a positive correlation between the number of sunspots and the amount of magnetic activity.
2. (4) in a cyclic pattern, repeating approximately every 11 years.
