Why is volcanic ash extrusive igneous rock?
Because if it was magma which is inside the earth will be intrusive but ash is on the earth so it is extrusive.
What are the sub categories of igneous rocks?
The two types are extrusive igneous rock, which solidifies from magma on the surface, and intrusive igneous rock, which solidifies below the surface. Basalt is extrusive, granite is intrusive.
Extrusive igneous rock are made from?
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.
What size crystal do magma make?
it depends on if it is intrusive or extrusive (intrusive is below the earth and extrusive is at or above the earth) intrusive has a bigger crystal because it takes time to cool down.
Is a dike a intrusive ingneouse rock or a extrusive rock ingneouse?
A dike is an intrusive igneous rock. It is a vertical intrusion that is usually associated with a central magma chamber. It is intrusive because it usually does not reach the surface. When a dike does reach the surface, the magma it countains erupts and forms an extrusive lava flow.
What is the difference between an intrusive and an extrusive igneous rocks?
"intrusive" means forced into something, "extrusive" means forced out onto the surface. The igneous magma reaching the surface is therefore extrusive , producing extrusive igneous rocks, and all the rest of the magma is intrusive, producing intrusive igneous rocks.
How are intrusive and extrusive ignious rock different?
Intrusive rick forms when the cooling and solidification of magma and extrusive is when the cooling and solidification of lava.
What are the main two types of igneous rocks?
Igneous rocks are classified as either extrusive or intrusive. Extrusive rocks form from lava at or above the ground, and intrusive rocks form from magma below the ground. Granite is intrusive, pumice is extrusive.
Does intrusive rocks have smaller minerals than extrusive rocks?
No. Intrusive rocks have larger crystals because the magma would have taken longer to cool and solidify than extrusive magma.
How do intrusive and igneous rocks differ?
Intrusive rocks are formed from magma below the surface; extrusive rocks are formed from magma on the surface of Earth.
What are the 2 kinda of igneous rock?
Extrusive and Intrusive. Extrusive rocks are formed from hardened lava at the surface and Intrusive rocks are formed from magma within the Earth.
Why is volcanic ash extrusive igneous rock?
Because if it was magma which is inside the earth will be intrusive but ash is on the earth so it is extrusive.
What are the sub categories of igneous rocks?
The two types are extrusive igneous rock, which solidifies from magma on the surface, and intrusive igneous rock, which solidifies below the surface. Basalt is extrusive, granite is intrusive.
What is the difference between a intrusive igneous rock ad an extrusive rock?
instrusive is inside the valcano and exstrusive comes onto earth's crust

What is the similar in intrusive and extrusive igneous rock?
Igneous rocks which form by the crystallization of magma.
