Carefully analyze each graph and answer the questions that follow. Use your knowledge of Earth Science to interpret the data presented.
The graph below shows average global temperature anomalies (°C) from 1880 to 2020, relative to a 1951-1980 baseline.
1. Describe the general trend in global temperature anomalies shown in the graph.
2. Approximately what was the temperature anomaly in the year 1950?
3. The Richter scale is used to measure the magnitude of earthquakes. Which of the following best describes the relationship between Richter scale magnitude and earthquake energy release?
Linear relationship, where energy doubles with each whole number increase.
Logarithmic relationship, where energy increases by a factor of 32 for each whole number increase.
Exponential relationship, where energy is directly proportional to the magnitude squared.
Inverse relationship, where energy decreases as magnitude increases.
4. The concentration of carbon dioxide in the atmosphere has been steadily increasing since the Industrial Revolution. This trend is often depicted using a graph known as the curve.
5. The primary anthropogenic source of the increased carbon dioxide levels is the burning of .
