Is dunite intrusive or extrusive?
Dunite is an intrusive igneous rock that forms from the cooling and solidification of magma beneath the Earth's surface. It is primarily composed of olivine mineral and is typically found in plutonic environments.
Example of intrusive rock?
Granite is an example of an intrusive rock. It forms when magma solidifies below the Earth's surface, resulting in a coarse-grained texture due to slow cooling. Intrusive rocks like granite are characterized by their large mineral crystals and are typically found in mountain ranges and continental landmasses.
What kind of rock is formed from magma that cools below the Earth's surface?
Igneous rock, such as granite or diorite, is formed from magma that cools below the Earth's surface. It has a coarse-grained texture due to the slow cooling process, allowing large mineral crystals to form.
What is the grain size of plutonic rock?
The grain size of plutonic rocks is generally coarse, with individual mineral grains typically larger than 1 mm in size. This is due to the slow cooling and crystallization process of magma beneath the Earth's surface, allowing for the growth of larger crystals.
What is igneous rocks that form below Eart's surface are called?
Igneous rocks that form below the Earth's surface are called intrusive or plutonic rocks. These rocks cool and solidify slowly, allowing large mineral crystals to form. Examples include granite and diorite.
What is an intrusive (plutonic) rock?
The mineral crystals within them are large enough to see without a microscope.

What are Igneous rocks that formed beneath Earth's surface called?
Igneous rocks that are formed deep inside earth are called intrusive igneous rocks. These rocks are created when magma cools over millions of years inside earth. As it is cools, elements combine and form minerals. Intrusive igneous rocks are usually identified because they have visible crystals.
What kind of rock is formed from magma that cools below the Earth's surface?
Igneous rock, such as granite or diorite, is formed from magma that cools below the Earth's surface. It has a coarse-grained texture due to the slow cooling process, allowing large mineral crystals to form.
What kind of mineral has a large grains?
Intrusive
What is the grain size of plutonic rock?
The grain size of plutonic rocks is generally coarse, with individual mineral grains typically larger than 1 mm in size. This is due to the slow cooling and crystallization process of magma beneath the Earth's surface, allowing for the growth of larger crystals.
What is igneous rocks that form below Eart's surface are called?
Igneous rocks that form below the Earth's surface are called intrusive or plutonic rocks. These rocks cool and solidify slowly, allowing large mineral crystals to form. Examples include granite and diorite.
What type of igneous rock has large mineral grains?
Intrusive igneous rocks since they have more time to cool, thus more time for the crystals o form and grow. So, examples of such igneous rocks will include:-Granite-Gabbro
The Igneous rocks that form under the surface?
Igneous rocks that form under the surface are called intrusive or plutonic rocks. These rocks cool slowly beneath the Earth's surface, allowing for the formation of large mineral crystals. Examples include granite, diorite, and gabbro.
How are intrusive and extrusive rock form?
Both are formed from the crystallization of minerals caused by the cooling of magma. Intrusive igneous rocks cooled below the surface of the planet, however, and generally display larger crystals due to the increased amount of time spent at mineral crystallization temperatures from the insulating effect of surrounding material. Extrusive rocks are formed from magma at or above the surface of the planet, and generally display smaller mineral crystals, or no crystals at all, because of the rapid cooling environment in which they form. Chemically, an intrusive and extrusive rock could be identical, the only difference being the size of the mineral crystals they contain.
Extrusive rocks which cool more rapidly than intrusive rocks generally have?
Extrusive rocks that cool more rapidly than intrusive rocks generally have a fine-grained texture with small mineral crystals. This rapid cooling prevents larger crystals from forming due to lack of time for crystal growth. Examples of such rocks include basalt and rhyolite.
