Final answer:
A history of Mount Rainier's eruptions can help assess the level of risk involved in hiking around the mountain by providing information on the volcanic activity.
Step-by-step explanation:
A history of Mount Rainier's eruptions can help you decide whether hiking around Mount Rainier is safe by providing information on the volcanic activity.
By analyzing the history of eruptions, you can determine the frequency and scale of past eruptions, which can give you an idea of the likelihood and severity of future eruptions. This information can help you assess the level of risk involved in hiking around the mountain.
For example, if Mount Rainier has a history of frequent and large-scale eruptions, it may indicate a higher level of volcanic activity and potential hazards such as ash clouds, pyroclastic flows, and lahars. On the other hand, if the volcano has a history of relatively infrequent and smaller eruptions, it may suggest a lower level of volcanic activity and a lower risk for hikers.
