What does igneous intrusive rock mean in science?

There are various types of igneous rocks. They can form either as lava (magma that hardens underground), as a crystallization of molten rock, or as solidified lava flows. They can be formed when magma intrudes into the Earth’s crust through cracks, fissures or faults. This type of rock formation is known as an intrusive body. The magma cools rapidly and crystallizes as it cools. The resulting rock is then called a crystalline intrusion.

What does igneous intrusive rocks mean in chemistry?

The word igneous comes from the Latin ignis and refers to the Latin root “to shine.” This type of rock is created when magma (molten rock) rises up from the earth’s interior to form a solidified layer on the surface. Though a single layer of solidified magma is called a dike, groups of dikes that form a linked body of rock are called an intrusion.

What does igneous intrusive rocks mean in physics?

In physics, igneous rocks are created through rapid solidification of molten magma. This process is known as magma crystallization and results in the creation of crystals in the magma. As the molten magma cools, the crystals can form a solidified rock. The resulting rock is an igneous intrusion, where the crystallized magma forms as a sheet or dike through the surrounding rock.

What does igneous intrusive rocks mean?

While extrusive rocks form as molten material erupts through the surface of the earth, intrusive rocks form underground. Their molten material gets trapped in cracks and faults in the earth’s crust. Because of the way they form, igneous intrusive rocks are typically much younger than extrusive rocks. They have crystallized from molten magma much more recently than extrusive rocks did.

What does igneous intrusive rocks mean in science?

Igneous intrusive rocks form under extremely high pressure conditions, up to several gigatons of force. Their crystalline structure is formed under these conditions. This means that their minerals are chemically bound together much more tightly than those in sedimentary rocks. This process is called solidification.
