Carefully analyze each graph and answer the questions that follow. Use your understanding of Earth science principles to interpret the data presented.
The graph below shows the average global temperature anomalies (°C) from 1880 to 2020. A positive anomaly indicates a temperature warmer than the long-term average, and a negative anomaly indicates a cooler temperature.
1. Describe the general trend of global temperature anomalies from 1880 to 2020.
2. During which period did global temperatures show the most significant increase?
3. The graph below illustrates the frequency of earthquakes (magnitude 5.0 and greater) over a 50-year period. What does the trend suggest about seismic activity?
Seismic activity is decreasing.
Seismic activity is increasing.
Seismic activity remains constant.
There is no discernible pattern.
4. The concentration of atmospheric carbon dioxide has been steadily over the past century, primarily due to .
5. The greenhouse effect is a natural process where certain gases in Earth's atmosphere trap from the sun, which helps to keep our planet warm enough to support life.
6. Explain how increased atmospheric carbon dioxide leads to ocean acidification. What are some potential consequences of this phenomenon on marine ecosystems?
7. The theory of plate tectonics suggests that Earth's lithosphere is divided into large plates that are constantly moving.
True
False
