Extrusive igneous rocks
What else can I help you with?
When igneous rocks from a volcanic eruption cools what does it form?
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.
Which type of rocks form when lava cools after a volcanic eruption?
Igneous rocks form when lava cools after a volcanic eruption. Specifically, when lava cools quickly on the Earth's surface, it typically forms extrusive igneous rocks, such as basalt or pumice. These rocks have a fine-grained texture due to the rapid cooling, which prevents large crystals from forming.
Many extrusive volcanic rocks contain holes which have formed from?
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.
What are rocks called that formed from volcanic process?
Those would be igneous rocks. Extrusive igneous rocks.
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.
When igneous rock from volcanic eruption cool what does it form?
When igneous rocks from a volcanic eruption cools it forms Crystalline Rocks.
What type of rocks form when lava cools after a volcanic eruption?
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 eruption are called what?
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.
When igneous rocks from a volcanic eruption cools what does it form?

Extrusive igneous rocks form when lava cools quickly on the Earth's surface, resulting in smaller mineral grains. Examples include basalt and pumice.
What does igneous rock made of?
Igneous rocks are formed when lava cools. After a eruption, the lava cools, and the igneous rock is formed.

What are rocks called that formed from volcanic process?
Those would be igneous rocks. Extrusive igneous rocks.
What kind of rocks that are formed by volcanic activity?
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.
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.
Magma that is rejected during a volcanic eruption forms igneous rocks?
Magma that is ejected during a volcanic eruption forms extrusive igneous rocks. They are also referred to as volcanic rocks.
How are rocks formed in a volcanic eruption?
They are formed when the erupted magma or lava, cool and sollidifies below or above the earths surface respectively.
