I wish I Knew the answer to this ? but i have a assignment that's due Wednesday and need to know Can someone Plz answer it ASAP
Thx Alot
Magma is formed by the partial melting of material within the Earth. The most common cause of this melting is due to changes in the melting temperature of this material.
This is caused either by a decrease in the confining pressure of mantle material which causes a decease in the melting temperature and is technically known as adiabatic decompression meltingor due to the presence of volatiles within the mantle material which exsolve from downgoing slabs during subduction.
Magma is composed of melted rock that has been cooled after it has been erupted through a volcano. The rocks within the magma are different types of minerals that have different melting points.
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.
magma is a mixture of molten rock, which is formed deep beneath the earth's surface, the magma itself is not made by volcanos as such, magma is constant beneath the earth everywhere as part of its layers, it helps to shift the tectonic plates, so in essance, magma itself is not made by volcanos, volcanos just release the magma when it erupts along with other gases and solids :)
I think it is made out of melted rock...
It also has some oxygen, hydrogen and a tiny little bit of water, if it had too much water in it, it would cause the melting temperature to drop by nearly 100 degrees.
Magma typically consists off silicon, oxygen, aluminum, magnesium, iron, calcium, sodium, potassium and titanium.
Oxygen and silicon make up 48-76% by weight
magma is made of the melted rock inside the mantel.
Molten rock with varying composition depending on the type of formation and source.
Hot rocks. The only difference of magma and lava is that lava is what it is called once it breaks through the earths crust.
Magma is just lave, but underground. it becomes lava when it touches air.
yes cinder cone volcano are made from magma
After magma reaches the surface it is no longer magma it is called lava.
magma rock
Extrusive Igneous rock is made from lava. Intrusive Igneous rock is made from magma. Magma and Lava are similar but magma is inside earth and lava is on the outside.
itis made of magma
Magma
Magma is made molten rock. Rock is made up of elements.

Lava and magma are composed of molten rock.

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.
A VOLCANO IS MADE UP OF COOLED MAGMA FROM THE EARTHS CORE
Some rock (igneous) is made from solidifying magma. Other rock is formed from different processes.
Igneoous rock is made from cooling of magma. Obsidian is a classic example of igneous rock.
