Extrusive igneous rocks
When igneous rocks from a volcanic eruption cool, they can form either intrusive or extrusive rocks. Intrusive igneous rocks form when magma cools slowly beneath the Earth's surface, resulting in larger mineral grains. Examples include granite and diorite. Extrusive igneous rocks form when lava cools quickly on the Earth's surface, resulting in smaller mineral grains. Examples include basalt and pumice.
Many extrusive volcanic rocks contain holes, or vesicles, which have formed from gases trapped in the magma during eruption. As the lava cools and solidifies, these gases escape, leaving behind the characteristic holes in the rock.
Those would be igneous rocks. Extrusive igneous rocks.
Magma that is ejected during a volcanic eruption forms extrusive igneous rocks. They are also referred to as volcanic 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.
When igneous rocks from a volcanic eruption cools it forms Crystalline Rocks.
Igneous Rock is formed when a volcano erupts and the the lava cools down to harden. Pumice Stone Extrusive Rocks Glass Rocks Hope this Helps :)
Rocks formed from volcanic eruptions are called igneous rocks. These rocks form when magma or lava cools and solidifies, either beneath the Earth's surface (intrusive) or at the surface (extrusive). Examples include basalt, rhyolite, and pumice.

Igneous rocks are formed when lava cools. After a eruption, the lava cools, and the igneous rock is formed.

Rocks formed by volcanic activity are called igneous rocks. These rocks form when molten magma cools and solidifies either above or below the Earth's surface. Examples of volcanic igneous rocks include basalt, andesite, and rhyolite.

They are formed when the erupted magma or lava, cool and sollidifies below or above the earths surface respectively.
Cinders are small, volcanic rocks or fragments that are ejected during a volcanic eruption. They are formed when magma is explosively expelled from a volcano and cools rapidly in the air, resulting in porous, lightweight particles. These cinders can accumulate around the volcano, contributing to the formation of volcanic landforms such as cinder cones. Their presence can impact the surrounding environment, including vegetation and air quality, during and after an eruption.
