What two ingredients in magma affects the type of explosion and shape of a volcano?
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.

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.
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.
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.

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
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.

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.
What is magma calle when it comes out of a volcano?
When magma comes out of a volcano, it is called Lava.
What is the difference between crater and magma chamber?
A crater can also be called a vent, and it is the funnel shaped opening at the top of a volcano which allows magma to escape as lava. The magma chamber is the hollow deep within the volcano which is supposedly linked to the core of the planet, bringing up molten rock from the middle of earth to be taken up the vent tube of the volcano to be released to the air.
