Please be sure to identify the test variable (independent variable), outcome variable (dependent variable), and control group for this experiment.

Explore the scientific theory of plate tectonics by describing how the movement of Earth's crustal plates causes both slow and rapid changes in Earth's surface, including volcanic eruptions, earthquakes, and mountain building.

There is no specific experiment mentioned in the prompt, so it is not possible to identify the test variable (independent variable), outcome variable (dependent variable), and control group for this scenario. The prompt is asking for a description of how the movement of Earth's crustal plates causes changes in Earth's surface such as volcanic eruptions, earthquakes, and mountain building. No specific experiment or variables are mentioned.
