Join us as we explore the fascinating world of volcanoes and their eruptions. In this article, we will delve into the two main types of volcanic eruptions: effusive and explosive. We will also discuss the experiments that help us understand the difference between these two types of eruptions.

[...] Different materials are emitted; they can be solid with projections, liquid in the form of lava or gaseous. Volcanic eruptions are thus of two types: - They are effusive and are characterized by a dominance of liquid products - They are explosive and are characterized by volcanic gases and projections and are VERY DANGEROUS. The volcanic eruption is therefore a manifestation of the Earth's internal energy that is usually accompanied by earthquakes. To avoid dramas, it is indispensable to predict volcanic risks by monitoring seismic activity and soil movements. [...]
[...] The ketchup comes out of the tube and slides along the walls like when an effusive volcanic eruption occurs. - For explosive eruption: You will have noticed that the mixture of ketchup and mashed potatoes comes out of the tube and forms a dome like when an effusive eruption occurs. What hypothesis can be formulated regarding the nature of the two types of eruptions? You need to know that under volcanoes there are areas where molten rocks containing gases dissolve. [...]
[...] What is a volcanic eruption? Modeling : Hello, my name is John and I'm a science journalist for the WAPITI magazine. To help you understand the difference between the two types of volcanic eruptions, I will present two experiments that will give you a clearer view. Let's get started To help you understand what an effusive eruption is: You slowly pour ketchup from one side of the tube and from the other you pour water using a pitcher You then close it using the plug on the side where the water is You place a saucer on the table just below the tube The experiment starts.
