According to the graph below, what can you say about the global surface temperature trend from 1850 to 1910 as compared to the years from 1910 to 2010?
the global surface temperature average was significantly lower during the period from 1850 to 1910.
the global surface temperature average was essentially similar during both periods.
the global surface temperature average was somewhat higher during the period from 1850 to 1910.
the global surface temperature average was significantly higher during the period from 1850 to 1910.

the answer is the first one. The global surface temperature average was significantly lower during the period from 1850 to 1910. I just took the test.

The global surface temperature average was significantly lower during the period from 1850 to 1910.

Explanation:

When you look at the graph, the period from 1850 to 1910 was low, and then the average temperatures spiked. This means that they are higher than those from the selected time period.

these civilizations were located around fertile rivers, where they could produce an abundance of crops
