Igneous rocks are formed when magma does what?
The Igneous rock formed when magma cools are; 1. Extrusive (Volcanic) Igneous Rock; which are igneous rocks formed when magma cools outside the earths crust. The texture of of extrusive igneous rock is fine grained. 2. Intrusive (Plutonic) Igneous Rock; these are igneous rocks formed by gradual cooling of magma within the earths crust. The texture is coarse grained.
What is determined by how magma cools and where it cools?
Its texture.
What is the texture for magma cooling in 2 stages?
When magma cools in two stages, it typically results in a texture known as porphyritic. In the first stage, magma cools slowly underground, allowing large crystals to form, known as phenocrysts. In the second stage, the magma erupts and cools rapidly at the surface, leading to a fine-grained matrix. This combination creates a rock with a distinct texture, featuring visible larger crystals set within a finer-grained background.
Do Glassy igneous rocks form when magma cools so slowly that mineral crystals cannot grow?
No, glassy igneous rocks form when magma cools so quickly that mineral crystals do not have time to form. This rapid cooling prevents the atoms in the magma from arranging themselves into a crystalline structure, resulting in an amorphous, glassy texture.
Magma that is ejected during a volcanic eruption forms igneous rocks?
Yes, when magma is ejected onto the Earth's surface during a volcanic eruption, it cools and solidifies to form igneous rocks. These rocks can vary in composition and texture depending on the type of magma and how fast it cools.

How does magma from igneous rock?
magma cools to form igneous rock
Magma cools and solidifies to form what rocks?
igneous rocks
What kind of igneous rock texture results from slow cooling magma?
A coarse grained texture, referred to as a phaneritic texture, will be the resultant igneous rock texture. The slower the magma cools the more time minerals have to crystallize and thus grow bigger.

Type of rocked formed when lave or magma cools?
A rock that is formed when magma cools is called a igneous rock.

How does igneous rock from?
magma cools to form igneous rock

When magma cools and hardens it becomes?
when magma cools slowly it becomes extrusive igneous rock
What kind of mineral does magma form when it cools?
When magma cools, it forms igneous rock.
