Question 7 of 12 Which of these volcanic eruption types is the least violent? A. Strombolian B. Hawaiian C. Plinian D. Pelean

## Step 1<br />The question asks us to identify the least violent type of volcanic eruption among the given options. The options are Strombolian, Hawaiian, Plinian, and Pelean.<br /><br />## Step 2<br />We need to understand the characteristics of each type of eruption. <br /><br />### **Strombolian eruptions** are characterized by moderate explosive activity, with incandescent cinder, lapilli, and lava bombs ejected from the vent.<br /><br />### **Hawaiian eruptions** are characterized by the effusion of fluid lava that flows out of the vent, with little explosive activity.<br /><br />### **Plinian eruptions** are characterized by explosive activity, with large volumes of pumice and ash ejected into the air.<br /><br />### **Pelean eruptions** are characterized by explosive activity, with large volumes of pumice and ash ejected into the air.<br /><br />## Step 3<br />Based on the characteristics of each type of eruption, we can see that Hawaiian eruptions are the least violent. They involve the effusion of fluid lava with little explosive activity, unlike the other types of eruptions which involve explosive activity and the ejection of large volumes of pumice and ash.
