Igneous Rock
Igneous rock is formed from cooled magma or lava. The magma turns solid as it cools, and eventually becomes rock. It is sometimes crystallized.

Do statues made of pumice erode away?
Yes, statues made of pumice would be susceptible to erosion over time due to its porous and brittle nature. Pumice is a lightweight, frothy volcanic rock that can easily break down when exposed to environmental factors like moisture, wind, and temperature fluctuations, causing it to gradually wear away. Regular maintenance and protective measures would be needed to preserve pumice statues.
Minerals in igneous rocks can show the direction of earths?
The Earth magnetic field changes approximately every 200,000 thousand years.
What is the process sedimentary to igneous?
In order to get an igneous rock from a sedimentary rock, the sedimentary rock must be melted and then that melt must crystallize.
What are igneous rocks used for?
Because they are so hard, Igneous rocks make useful road building materials. When sheets of igneous rock are cut and polished, they are used inside buildings such as banks and offices, and are also used as gravestones. There are different types of igneous rock, therefore each type has its own uses, such as: Granite: Used for long lasting monuments, for trim and decoration on buildings. Pumice: Because they are so light, it is used quite often as a decorative landscape stone. If grounded to a powder, it is used as an abrasive in polish compounds and in Lava soap. Crystalline Igneous rocks can be used for jewelery and other similar things. Countertops and building stone. Lava soap, building materials, landscaping
HOW does composition layering occur in igneous bodies?
A layered intrusion is a large sill-like body of igneous rock which exhibits vertical layering or differences in composition and texture.
No diamond cannot form in basalt. Diamond only form in Kimberlite because it develop only at very low cooling rate.
Granite is a dense, natural stone that typically does not have air holes. However, some varieties of granite may contain tiny pores or fissures, which can sometimes be filled with resin during the finishing process to enhance the stone's appearance and durability.
What is the extrusive equivalent of peridotite?
It's very rare to have an extrusive Peridotite, but under the right conditions Komatite can form. It's similar in appearance to Basalt, but has long ( anywhere between 1-10 cm) criss-crossing needles of olivine or pyroxene.
Why does pumice have no crystal structure?
Pumice is made of glass. Glass forms when molten rock cools too quickly for crystals to form.
Are dark colored igneous rocks low in silicate minerals?
They are not low in silicate minerals. They are still primarily composed of them. However, the amount of silica in them is lower than in the lighter-colored rocks. The lightest igneous rocks (felsic) are at least 70% silica while the dark ones (mafic) are between 45% and 52% silica. Silica content below 45% is deemed ultramafic.
Did gabbro cool fast or slowly?
Gabbro cooled slowly underground, resulting in the formation of coarse-grained crystals in the rock. This slow cooling process allows large crystals to grow and develop in the molten rock.
The stone called, "Decomposed Granite" is orange (and a little crumbly).
A lot of granite is composed of white and black minerals in a speckled appearance.
No. It is volcanic. The plutonic equivalent of andesite is diorite.
What type of rock is formed by cool lava or magma?
An igneous rock is formed when magma cools and hardens. Some examples of igneous rocks are pumice and obsidian.
What is a texture where you cannot see the individual minerals in igneous rocks?
It depends on what texture pack your using i recomend lookoing on Minecraft.net
