Magma is molten rock that bubbles up along ocean ridges to form new crust. Another way that magma forms new crust is when it is expelled out of a volcano and becomes lava, which cools and hardens into crust.

∙ 13y ago1. Magma can force the overlying rock apart and enter the newly formed fissures.
2. Magma can cause blocks of rock to break off and sink into the magma, where the rocks may eventually melt.
3. Magma can melt the rock into which it intrudes.

How does the pH of magma affect the formation of igneous rocks?
ybyg
What kind of rock forms when magma intrudes into other rocks?
Intrusive igneous rocks. These have large crystals because it is warmer underground, therefore it has more time to cool, therefore the crystals have more time to form and grow, thus large crystals.
What does magma have to do with igneous rocks?
Igneous rocks are formed by cooling magma.
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.
Are rocks formed by lava or magma?

Rocks are formed when magma does what?
Rocks are formed when magma cools.
What does magma have to do with igneous rocks?
Igneous rocks are formed by cooling magma.

Rocks that form as a result of cooling magma?
Rocks formed from magma are igneous rocks. Extrusive igneous rocks form from lava at or near the surface. Intrusive rocks form from magma below the surface.
How does the composition of the magma affect the temperature which it solidifies?
Magma consists of molten rocks and metals. The composition can vary based on presence of water, metals with different melting points, and such.
Are rocks formed by lava or magma?
Magma
What rocks are formed by magma?
Intrusive igneous rocks are formed by magma. Magma can also cause the contact metamorphism of rock that it is intruded into.
Rocks made by the cooling of magma are called?
Intrusive igneous rocks are formed by the cooling of magma.
Do sedimentary rocks melt and become magma?
No. It's the Metamorphic rocks that melt and become magma.
How does magma form into ignous rocks?
igneous rocks are formed through the cooling and solidification of magma.
