How is basalt different from gabbro?
Basalt and gabbro are both igneous rocks, with major differences in grain size and where they form. Basalt has fine-grained crystals and forms from lava flows on the Earth's surface, while gabbro has coarse-grained crystals and forms from magma cooling beneath the Earth's surface.
What is the difference between rhyolite and granite?
Rhyolite is a fine-grained, extrusive igneous rock with high silica content, while granite is a coarse-grained, intrusive igneous rock also rich in silica but with larger crystals. Rhyolite forms from cooled lava flows on the Earth's surface, while granite forms from slowly cooling magma beneath the surface.
What is the difference between fine and coarse grained igneous rock?
Coarse grained textured rocks (phaneritic) have very large crystals because the magma, from which they are created, cools very slowly. Fine grained rocks (aphaneritic) have small crystals because the lava, from which they are created, cools down very quickly.
What is the relationship between basalt gabbro and obsidian?
Basalt and gabbro are both igneous rocks that form from the cooling and solidification of magma. Basalt is fine-grained and forms from lava flows on the Earth's surface, while gabbro is coarse-grained and forms from magma that cools beneath the surface. Obsidian is a volcanic glass that forms when lava with a high silica content cools rapidly, without time for crystal growth, resulting in a smooth, glassy texture.
Is the following is an intrusive igneous body Pyroclast Lava Flow Lahar Batholith?
The given options are not all intrusive igneous bodies. A batholith is an intrusive igneous body formed deep within the Earth's crust, while pyroclastic flows, lava flows, and lahars are volcanic hazards associated with volcanic eruptions.

Rhyolite forms from cooled lava flows on the Earth's surface, while granite forms from slowly cooling magma beneath the surface.
Where would igneous rock cool rapidly?
Igneous rock cools rapidly at or near the Earth's surface, such as during volcanic eruptions when lava flows or volcanic ash are exposed to air or water. This rapid cooling leads to the formation of fine-grained textures in the rock, characteristic of extrusive igneous rocks like basalt and pumice. Conversely, if the magma cools slowly beneath the surface, it forms coarse-grained intrusive igneous rocks like granite.
What is the difference between fine and coarse grained igneous rock?
Coarse grained textured rocks (phaneritic) have very large crystals because the magma, from which they are created, cools very slowly. Fine grained rocks (aphaneritic) have small crystals because the lava, from which they are created, cools down very quickly.

Does intrusive have lava or magma?
Intrusive igneous rocks form when magma cools below the Earth's surface. Thus, intrusive rocks are associated with magma. Lava, on the other hand, is molten rock that flows onto the Earth's surface, forming extrusive igneous rocks.
Who are not an intrusive igneous body?
Non-intrusive igneous bodies, also known as extrusive igneous formations, are those that form on the Earth's surface rather than beneath it. Examples include volcanic rocks such as basalt and pumice, created from lava that cools quickly after erupting. These bodies contrast with intrusive igneous bodies, like granite, which crystallize slowly underground. Non-intrusive formations are typically associated with volcanic activity and can include features like lava flows and volcanic ash deposits.

What rock is formed inside a volcano?
according to my science class, its igneous rock. igneous rock is formed when magma/lava cools. if it cools slowly, it is conglomerate (coarse-grained or heavily grained..chunky.) if it cools fastly, it is fine grained (smooth.) i hope this helps!
What is a intrusive volcano?
An intrusive volcano is a type of volcano that forms from magma that solidifies below the Earth's surface. The magma cools and hardens over time, forming intrusive rock formations such as dikes, sills, and batholiths. Unlike extrusive volcanoes, intrusive volcanoes do not result in eruptions or lava flows on the surface.
What are the ways igneous rock can form?
intrusive igneous rock: magma cools and hardens in the earth and later forms an intrusive igneous rock. extrusive igneous rock: magma flows onto earth's surface and becomes lava. Then, lava cools and hardens above earth's surface and later forms an extrusive igneous rock.
Rhyolite is an example of a?
A rhyolite volcano is a volcano that erupts rhyolitic lava or pyroclasitc material. Rhyolite is an igneous rock formed from the eruption of extremely viscous silica rich material. Eruptions involving rhyolite can be extremely large and violent. In some cases, however, rhyolite can build into lava domes or form thick, extremely slow lava flows.
