1. The data right shows the temperature data for the Kola Superdeep Borehole. Plot the data. When plotting depth data, the depth should be plotted descending on the y-axis. 2. Describe the shape of the graph and what it shows:

3. Draw a line of best fit through the data and use it to determine the rate of temperature increased per meter:

4. What would you expect to happen to the temperature if depth was increased?
