How igneous rock classified?
Geologists classify rocks by where they are formed; above ground or under ground
Rocks formed from molten earth materials are?
Igneous rocks are formed from molten earth materials such as magma or lava. These rocks can be further classified into intrusive (formed below the Earth's surface) and extrusive (formed on the Earth's surface) based on their origin. Examples of igneous rocks include granite, basalt, and obsidian.
Is gabbro an intrusive or extrusive igneous rock how do you know?
Intrusive, or plutonic, based upon the size of the crystals. Intrusive igneous rocks tend to have larger and more developed crystals than volcanic igneous rocks because of minimal exposure to air, causing the magma to cool more slowly.
How do igneous rocks form and how are they classified?
Igneous rocks are formed by the cooling of lava (above Earth's surface) or magma (below). Rocks in general are classified by their mineral composition, texture, and origin. Igneous rocks all have the origin of molten material, there are two categories within this: intrusive and extrusive. Intrusive rocks formed below earth's surface and extrusive rocks above. Their mineral composition varies greatly and depends on each individual rock. The classification of igneous rocks in texture is linked to their origin. The texture of a rock is defined by its grain: can you see and feel the little rocks that make it up? If you can, that rock has a coarse grain, if you can't see the bits, it is fine grained. Intrusive igneous rocks are usually fine grained; extrusive, coarse grained.
What is igneous rock?
Igneous rock is one of the three main rock types based on the method of its formation. It is also referred to as plutonic or volcanic rock depending on where it formed. In a nutshell, to be classified as igneous, a rock must have crystallized and solidified from molten rock (magma) either below ground (intrusive igneous rock) or at or near the surface (extrusive igneous rock).
Are magmas classified as intrusive and extrusive?
Yes, magmas can be classified as intrusive or extrusive. Intrusive magmas cool and solidify beneath the Earth's surface, forming intrusive igneous rocks like granite. Extrusive magmas erupt onto the Earth's surface and solidify quickly, forming extrusive igneous rocks like basalt.

Igneous rocks are classified among there?
Igneous rocks are classified into two main categories: intrusive (or plutonic) and extrusive (or volcanic) rocks. Intrusive igneous rocks form from the slow cooling and solidification of magma beneath the Earth's surface, resulting in larger crystals, while extrusive igneous rocks form from the rapid cooling of lava at the surface, leading to smaller crystals. Additionally, they can be further categorized based on their mineral composition into felsic, intermediate, mafic, and ultramafic types.

What two methods are used to group igneous rocks?
Igneous rocks can be either intrusive or extrusive, based on their location upon solidification from magma. Igneous rocks can also be grouped by chemistry and mineral content as felsic, intermediate, or mafic, mainly on the abundance of silicate minerals that are present.

Was igneous rocks were classified by their their origin texture and shape?
No, igneous rocks are not classified by their shape. They are primarily classified based on their origin (either intrusive or extrusive) and their texture (coarse-grained, fine-grained, glassy, etc.). Shape or form is not a major factor in the classification of igneous rocks.
How are igneous rocks grouped into families?
Extrusive- formed when lava was erupted onto the Earth's surface (overground) and cooled and solidified. Intrusive- formed when magma cooled and solidified at a shallow zone within the Earth's crust (underground).
Igneous rock are classified based upon their?
There are two types of igneous rocks; intrusive and extrusive. Intrusive igneous rocks are formed underneath the earth's surface from magma where it cools slower and develops large crystal structures. Extrusive igneous rocks are formed above the earth's surface from lava that cools quickly and creates rocks with smaller, finer crystal structures.
