What is a felsic intrusive rock?
A felsic intrusive rock is a type of igneous rock that is rich in silica and aluminum minerals. These rocks form from the slow cooling of magma below the Earth's surface, allowing large mineral crystals to develop. Granite is a common example of a felsic intrusive rock.
How does intrusive rock form?
intrusive rock froms when magma cools or hardens underneath the earth. :)
Why do intrusive igneous rocks have shiny appearances?
Intrusive igneous rocks, such as granite, have shiny appearances due to the presence of minerals like quartz and feldspar with reflective surfaces. These minerals can form large, interlocking crystals within the rock, which reflect light and give the rock a shiny or sparkly appearance.
Where does intrusive rock form?

Is intrusive rock is also called platonic rock?
No, intrusive rock is not also called platonic rock. Plutonic rock is another name for this type of rock, which is produced by magma.
Is a gabbro a intrusive rock or a extrusive rock?

Is schist an intrusive or extrusive rock?

What hardens and cools beneath earth's surface when an intrusive igneous rock forms?
The substance that cools beneath the earths surface when an intrusive igneous rock forms is Magma. Magma is a molten material made up of rocks and minerals.
Is diorite intrusive or extrusive?
Diorite is an intrusive igneous rock, formed from the cooling and solidification of magma beneath the Earth's surface. It contains a mix of minerals such as plagioclase feldspar, biotite, hornblende, and pyroxene.
What type of grains does an intrusive rook have?
An intrusive rock typically contains coarse-grained minerals, such as feldspar, quartz, and mica. These minerals were able to grow larger due to the slow cooling process of intrusive rocks beneath the Earth's surface.
How can rock minerals form?
Rock minerals form from lava, magma or solutions.
