Magma with high silica content
A volcanologist would study the cooling of lava after a volcanic eruption. They study the behavior of volcanoes, including the properties and processes of molten rock (magma) such as its cooling and solidification. By understanding these processes, volcanologists can make predictions about volcanic behavior and hazards.
Because it all depends on what type of volcano it is, if it is a shield volcano low and flat it's eruptions will be gentle. But if it is a cone volcano tall and steep it's eruptions will be very violent.
Volcanic bombs, lapilli, and ash are all types of tephra, which refers to any fragments of volcanic rock and lava that are explosively ejected during a volcanic eruption. Volcanic bombs are large, aerodynamic clasts that cool in flight, lapilli are small rock fragments ranging from 2 to 64 mm in size, and ash consists of fine particles less than 2 mm in diameter. Together, they make up the different-sized components of tephra fallout from volcanic eruptions.
The Cascade Mountains are primarily made up of volcanic rocks, such as basalt and andesite, due to the region's history of volcanic activity. These rocks were formed by the eruption of the Cascade Range's numerous stratovolcanoes, which have shaped the landscape of the region over millions of years.
1. Destructive plate boundaries. The oceanic crust is heavy and the continental crust is not heavy so sometines the oceanic crust sinks to the mantle and the magma chamber beneath. 2. This procedure has created extra lava in the mantle. This magma (lava) must come out somewhere this is where volcano's come into it. 3. After a while too much magma builds up this causes volcanic eruptions. 4. You will hear grumbling and ash will be released before an eruption. 5. During the eruption lava will shoot out of the volcano and volcanic rock. Pyroclastic clouds may come out of a violent volcano. 6. Steam gas and dust are dispersed out of the volcano lava will run down the sides. The thickness of the lava changes the shape of it, runny lava will make a flat volcano and thick lava will make your typical cone shaped volcano. Sorry there are only 6 steps here :) There are 3 different types of volcanoes: -Dormant = Has not erupted for a very long time-sleeping volcano -Active = Erupting all the time -Extinct = Will never erupt again. Hope this helps!:)x
Magma with low viscosity
The cloud of ash, gas, and rock fragments that is produced during a volcanic eruption is called a volcanic plume or eruption cloud.
Yes, scientists can predict volcanic eruptions, but only to a certain extent of accuracy. One method is to use earthquakes. Earthquakes usually increase and become more violent before a volcanic eruption
The main theory was that it was the workings of the gods.
Yes! It does make a new land form!
The answer is : Magma with low viscosity. It makes for a weak volcanic eruption. If the viscosity is low (thin), non-explosive eruptions usually begin with fire fountains due to release of dissolved gases. When magma reaches the surface of the earth, it is called lava.
Make troughs to lead the lava away from cities/towns

By understanding these processes, volcanologists can make predictions about volcanic behavior and hazards.
Geologists can make general predictions about the potential power of a volcanic eruption based on the volcano's past behavior, type of volcano, and monitoring data such as seismic activity and gas emissions. However, predicting the exact magnitude and timing of an eruption remains challenging due to the complex and dynamic nature of volcanic systems.
Yes it is. Volcanic eruptions are the product of certain types of the earths tectonic plate interaction. The tectonic plates make up the earth.
