The graph below shows the number of sunspots observed between 1750 and 2000. Based on the graph, which of these periods most likely witnessed the greatest increase in solar radiation? (2 points)

1750 to 1800

1850 to 1900

1900 to 1950

1950 to 2000

Most definitely 1950 to 2000; the sharpest and highest spike is there.

Explanation:

This is just based on the image of the graph, and the number of sunspots correlates with the amount of solar radiation. Also this fits with the theory/phenomenon of global warming and increasing radiation from the sun, which is some outside knowledge that supports this.

Hope this helped, and hope you're doing ok amidst these ongoing conflicts today. :)

a and c are the answeres

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
