Magma that is rejected during a volcanic eruption forms igneous rocks?
Magma that is ejected during a volcanic eruption forms extrusive igneous rocks. They are also referred to as volcanic rocks.
Lava is magma that has reached the what in an eruption?
Lava is magma that has reached the surface of the earth in an eruption. When this cools down, it will form igneous rocks.
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 are the sequence of events leading to a volcanic eruption-?
During a volcanic eruption, magma moves in an upward direction towards the vent of a volcano. The type of eruption depends on the amount of silica and gas. After the eruption, magma touches the earth's surface and is classified as lava. Rocks and other debris in the volcano are forcefully pushed into the air. The rocks are called pyroclastic rocks. When the rocks touch earth, it turns into ash, dust, pummice or cinder.
Why are all extrusive rocks made from lava and not magma?
Magma contains rocks which are not suitable for making extrusive rocks. Magma is only inside the chamber of a volcano, and comes out as lava. There is 98.3% Magma will be made into extrusive rocks.

What is the different between phreatic volcanic eruption and a strombolian eruption?
A Strombolian eruption is a type of magmatic eruption, meaning that molten rock actually erupts onto the surface. In a Stombolian eruption gasses trapped in the magma expand explosively, sending fountains of lava into the air. A phreatic eruption does not directly involve molten rock. Phreatic eruptions occur when water comes incontact with magma or hot rocks near magma and turns to steam, creating an explosion. Some ash may be ejected from these eruptions, but this is formed from the explosion blasting old rock rather than fresh magma.

What causes small earthquakes before a volcanic eruption?
The earthquakes are caused by the movement of magma underground and the breaking of rocks by that magma.
What are the crystal structures in porphyritic rocks?
They're called phenocrysts, allowed to slowly cool in magma before eruption of the magma.
What is magma made of?
Magma is highly heated molten rock that comes to the surface of usually through volcanic eruption. Magma is usually found beneath the earth located near the earth's core and can sometimes contain crystals and gases.

What is matter such as magma and rocks forcibly expelled from a volcano vent during an eruption called?
Ejecta
How is volcano eruption occur?
There are hot gases mixed with magma. Sometimes the pressure of the magma and hot gases increased a great deal when this happens the rocks deep inside the earth have melted on molten rocks which is called magma. This is how a magma occurs.
What comes out of volcanoes when there is an eruption?
well, lava comes out and extrusive igneous rocks:))
