texture
Igneous rocks are classified based on their mineral composition, texture, and formation process. The minerals present in the rock, the size of the grains, and whether the rock formed beneath the Earth's surface (intrusive) or on the surface (extrusive) are key factors in classification.
Rocks are classified as igneous, sedimentary, or metamorphic based primarily on their origin and how they were formed. Igneous rocks are formed from cooled magma or lava, sedimentary rocks are formed from the accumulation of sediments, and metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure.
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.
And their texture, which can be aphanitic, phaneritic, glassy, or porphyritic. mineral composition and crystal texture
Igneous rocks can be classified based on their texture and mineral composition. Texture is determined by the size of the mineral grains, with coarse-grained rocks forming from slow cooling and fine-grained rocks forming from rapid cooling. Mineral composition can also help differentiate igneous rocks, such as identifying the presence of minerals like quartz, feldspar, or olivine.
Igneous rocks are classified based on mineral composition and texture, metamorphic rocks are classified by texture and mineral composition, and sedimentary rocks are primarily classified by their grain size and composition. These classifications help scientists understand the origin and characteristics of each type of rock.
Igneous rocks are classified by either being intrusive or extrusive, then mafic or felsic then they are classified by either fine grain or course grained textures.

Igneous rocks can be classified by their method of formation and by their mineralogy.
A rock is an agglomeration of different minerals. Minerals are classified into categories based on their chemistry: oxides, sulphides, silicates, carbonates etc. Rocks are classified primarily by the process that formed them: igneous, sedimentary, or metamorphic.
Look at them. There shape, size, color and feel! Dont worry you will figure it out....
Igneous rocks are classified based on their mineral composition, texture, and origin. They can be divided into two main categories: intrusive rocks, which form from magma cooling beneath the Earth's surface, and extrusive rocks, which form from lava cooling on the Earth's surface or in the air. Within these categories, igneous rocks can then be further classified into specific types based on their mineral content and texture.
Geologists classify rocks by where they are formed; above ground or under ground
A rock formed from cooling lava is classified as an igneous rock. Igneous rocks are formed from the cooling and solidification of magma/lava. They can be further classified based on their mineral composition, texture, and formation process.

Rocks are divided into three main categories based on how they are formed: igneous, sedimentary, and metamorphic rocks. These categories are further broken down into subcategories based on specific properties such as mineral content, texture, and formation processes. For example, igneous rocks can be classified as intrusive or extrusive based on where they formed within the Earth's crust.
