When igneous rocks from a volcanic eruption cools it forms Crystalline Rocks.

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.
What rock is formed when a volcano explodes?
An andesite rock. it came out of the volcanic eruption of Mt. St. Helens...
Which type of rock would you expect to form as a result of an explosive eruption?
igneous rock answ2. Volcanic bombs, volcanic ash, pumice, ignimbrite.
Magma that has reached the earths surface?
When magma reaches the Earth's surface, it is called lava. Lava can flow out of a volcano during an eruption and can cool to form igneous rocks. The characteristics of the lava, such as its temperature and composition, can influence the type of volcanic eruption that occurs.
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.
What igneous rock would form from magma if it did not reach the surface but instead crystallized?
Intrusive igneous rock would form. Granite is an example. If the same magma that formed the granite had reached the surface through volcanic eruption, the extrusive igneous rock rhyolite would form.
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 :)
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.
Why do igneous rocks form?
Volcanic activity will produce igneous rock.
How does a volcanic eruption form?
preasure
What are igneous rocks that form over the surface?
Rhyolititcen rocks.
Which rocks form after an explosive eruption?
Igneous Rock.
