Porphyritic
please anyone else can answer this question I'm in hurry pls.
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.
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.

And their texture, which can be aphanitic, phaneritic, glassy, or porphyritic. mineral composition and crystal texture

Obsidian is an igneous rock that has a smooth glass-like texture. It is formed when lava cools rapidly without crystal formation, resulting in a glassy texture.
Igneous rocks are classified based on their composition and texture. Composition is determined by the minerals present, while texture refers to the size of the mineral grains in the rock. These classifications help geologists understand the conditions under which the rock formed.
The size of the mineral crystals in an igneous rock determines the rock's texture.

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.
Small crystal grains form when molten rock cools quickly. In an extrusive igneous rock, it's referred to as aphanitic texture.
