Where are big crystals are made in volcano?
the magma chamber and then they erupted onto the surface, where the small crystals were formed.
Is it true Extrusions are formed by cooling magma beneath Earth's surface?
No, extrusions are formed when magma reaches the Earth's surface and cools quickly. This rapid cooling allows extrusive rocks to form small crystals or glassy textures.
What are extrusive and intrusive in properties of matter?
Extrusive rocks are formed from magma that cools quickly on the Earth's surface, resulting in small crystals or glassy texture. Intrusive rocks are formed from magma that cools slowly beneath the Earth's surface, resulting in larger crystals due to slower cooling. These differences in cooling rates affect the texture and appearance of the rocks.
What is the extrusive form of granite with extremely small crystals and a red pink or gray color?
The extrusive form of granite with extremely small crystals and a red, pink, or gray color is called rhyolite. Rhyolite is formed from magma that cools quickly at the Earth's surface, resulting in its fine-grained texture.
What does porphyrytic texture indicate about the story of an igneous rock?
it tells you that the igneous rock formed in two stages,stage one occurred deep into the earth were large crystals formed from and then it eruptedas a volcano in stage two were small crystals formed
What are Igneous rocks that have large crystals and small crystals?
Igneous rocks with large crystals are called intrusive rocks, formed from magma cooling slowly beneath the Earth's surface, allowing for large crystals to form. Igneous rocks with small crystals are called extrusive rocks, formed from lava cooling quickly on the Earth's surface, resulting in small crystals due to rapid cooling.

No, extrusions are formed when magma reaches the Earth's surface and cools quickly. This rapid cooling allows extrusive rocks to form small crystals or glassy textures.
A mineral specimen has very small crystals what is the best explanation for how this happened?
The small crystals likely formed due to rapid cooling of the molten rock or solution from which the mineral precipitated. This rapid cooling did not allow enough time for the crystals to grow larger, resulting in the formation of small crystals.
Andesite has small crystals because?
Andesite has small crystals because it formed from lava that cooled relatively quickly at the Earth's surface, preventing larger crystals from growing. Rapid cooling does not allow enough time for the minerals to crystallize fully, resulting in smaller crystal sizes.
Where does Igneous rock form below or above?
Igneous rocks are formed from the cooling of lava/magma. (Lava is magma that has been moved from beneath the Earth's surface to above.) They can be formed above or below the Earth's surface- when formed above is called 'Extrusive Igneous rock' and when formed below is 'Intrusive Igneous rock'. When a rock is extrusive, it forms small crystals. When it is intrusive, it causes large crystals to form.

Intrusive rocks are formed from magma that cools slowly beneath the Earth's surface, resulting in larger crystals due to slower cooling. These differences in cooling rates affect the texture and appearance of the rocks.
How do igneous rocks produce big or small crystals?
The small crystals are formed outside the volcano by the cold air... the cold air cools down the igneous rock and the crystals dont have time to join together so the are small. And the big crystals are formed inside the volcano very slowly and that way they have time to join together then there are big crystals that have been formed.
Do igneous rocks have small crystals large crystals or no crystals?
Igneous rocks can have both small and large crystals, depending on how quickly they cool. If an igneous rock cools slowly beneath the Earth's surface, it can form large crystals, while rapid cooling at the Earth's surface or in an eruption can result in small or no visible crystals.
What does the presence of large crystals tell you about the rock's formation?
Large crystals in a rock indicate slow cooling and crystallization, allowing mineral grains to grow to a larger size. This suggests that the rock formed deep within the Earth's crust or even in the mantle. Conversely, rocks with small crystals or glassy textures are typically formed from rapid cooling at the Earth's surface.
Why do some igneous rocks have large crystals while others have small crystals or no crystals?
Mostly, it depends on cooling time. If a rock cools very rapidly, a smooth texture is formed as the atoms quickly arrange themselves into a fairly smooth crystalline pattern. Think of obsidian; it cools very fast and has such small crystals looks like black warped glass. However, if a rock was formed below the Earth's surface (intrusively) like in a pluton, it will cool more slowly and will be rougher and have larger crystals.
What is the extrusive form of granite with extremely small crystals and a red pink or gray color?
The extrusive form of granite with extremely small crystals and a red, pink, or gray color is called rhyolite. Rhyolite is formed from magma that cools quickly at the Earth's surface, resulting in its fine-grained texture.
