water and mantle rock
+++
More specifically, the silica proportion, plus water and gases from entrained wet, organic-rich sediment if the volcano is from subduction rather than a constructive plate margin. Increasing silica increases the magma's viscosity; the water and gas make it effervesce in the eruption.

Does the weather cause a volcano to erupt?
No because weather has no affect on the earth mantle and the mantle is the source of magma for the volcano.
What does underground water do to a volcano?
Groundwater that comes in contact with magma or rocks heated by magma can boil into steam. If it boils quickly enough it can result in an explosion called a phreatic eruption.
How do you think the location of a volcano affects the magma composition?
The location of a volcano can affect the magma composition by influencing the source of the magma. Magma composition can vary based on factors like the depth of the magma source, the presence of subducted materials, and the amount of water and gases present. Different locations can have different geological conditions that influence the composition of the magma erupted by a volcano.

How can you make a volcano explode?
A volcano can explode when pressure builds up inside it due to trapped gases and magma. This pressure can be released explosively when the volcano erupts, causing an explosion.

Is lava magma?
yes. magma is the lava that is in the volcano and lava is the magma that is outside a volcano
How does the high water content affect the explosiveness of volcanoes?
High water content can increase the explosiveness of volcanoes because it promotes the formation of steam and gas bubbles in magma, building up pressure that can lead to explosive eruptions. When water interacts with magma, it can cause rapid expansion and fragmentation of the magma, creating explosive eruptions with ash clouds and pyroclastic flows.
Why doesn't a volcano mountain explode everyday if the lava is always hot?
There are several reasons. First, there isn't always magma (what lava is called when it is underground). The magma is usually trapped far below the volcano, unless the volcano is erupting or about to erupt. Second, heat alone cannot create an explosion. An explosion requires rapid expansion. Explosive volcanic eruptions occur when gas trapped in the magma is suddenly released as pressure on the magma decreases, or when water flash boils on contact with lava or magma. If there is no gas, and no water, there cannot be an explosive eruption. Third, the kinds of magma most likely to cause explosive eruptions are very viscous, meaning they do not flow very easily. As a result, they tend to get "stuck." Finally, the poper term is "erupt" not "explode" as not all eruptions are explosive. If there is not enough gas the volcano will ooze out lava rather than causing an explosion.
What makes a volcano explode for kids?
A volcano explodes when magma (what lava is called when it is underground) comes up with gas trapped in it. The gas can form bubbles in the magma that grow so quickly that it creates an explosion. The real word for this is "erupt" because not all eruptions have explosions. Sometimes the lava just oozes out from the weight of the rock pressing down on the magma.
Where is the magma in a volcano?
In a magma chamber
How does an ash cloud come out of a volcano?
There are two ways a volcano can produce an ash cloud. In most cases gas-rich magma rises inside the volcano. The gas is dissolved in the magma under pressure. As the magma approaches the surface the pressure decreases and the gas is released and expands rapidly, producing an explosion. The magma is blasted apart into tiny particles, which we call ash. The hot gasses then rise, taking much of the ash with them. In other gases, water inside a volcano may come in contact with magma or rocks heated by magma, causing steam explosions. These explosions pulverize some of the rock inside the volcano, during it into ash.
