Is feldspar extrusive or intrusive?
Feldspar can be found in both extrusive and intrusive igneous rocks. In extrusive rocks, feldspar forms when magma cools and solidifies quickly on the Earth's surface. In intrusive rocks, feldspar forms as magma cools and solidifies slowly beneath the Earth's surface.
Can rocks both have igneous and intrusive?
Rocks can be classified as either igneous or intrusive, but not both. Igneous rocks are formed from the cooling and solidification of magma (molten rock) above or below the Earth's surface. Intrusive rocks specifically form from magma that cools and solidifies underground, beneath the Earth's surface.
Is peridot an intrusive or extrusive igneous rock?
Peridot is olivine, which is a mineral, not a rock. It is found in both intrusive and extrusive rocks.
Are all igneous rocks formed inside the earth?
No, igneous rocks can be formed both inside the Earth (intrusive or plutonic) and on the Earth's surface (extrusive or volcanic). Intrusive rocks form underground when magma cools slowly, while extrusive rocks form on the surface when lava cools rapidly.
Which igneous rock can be intrusive and extrusive?
A porphyritic igneous rock demonstrates some extrusive characteristics and some intrusive characteristics. The appearance of phenocrysts (larger crystals) in a fine matrix (small crystals) indicates that the magma had time to cool slowly enough underground to form larger crystals before being erupted at or near the surface.
Is schist an intrusive or extrusive rock?
Neither, Igneous rock is either intrusive or extrusive. Thats what intrusive and extrusive is... A igneous rock.
Is feldspar extrusive or intrusive?
Feldspar can be found in both extrusive and intrusive igneous rocks. In extrusive rocks, feldspar forms when magma cools and solidifies quickly on the Earth's surface. In intrusive rocks, feldspar forms as magma cools and solidifies slowly beneath the Earth's surface.
What type of rock can be intrusive and extrusive?
Igneous rock can be both intrusive and extrusive. Intrusive igneous rocks form from magma that cools beneath the Earth's surface, while extrusive igneous rocks form from lava that cools on the Earth's surface. Examples of intrusive igneous rocks include granite and diorite, while examples of extrusive igneous rocks include basalt and rhyolite.
Is silica intrusive or extrusive?
The terms intrusive and extrusive apply to the formation of igneous rocks. Silica is a chemical component of a wide variety of minerals found in many types of igneous, metamorphic, and sedimentary rock. All igneous rocks, both intrusive and extrusive, contain silica.
Is apatite intrusive or extrusive?
Apatite is typically found as an accessory mineral in both intrusive and extrusive igneous rocks. It is more common in intrusive rocks like granite, but can also be found in extrusive rocks like basalt.
Can rocks both have igneous and intrusive?
Rocks can be classified as either igneous or intrusive, but not both. Igneous rocks are formed from the cooling and solidification of magma (molten rock) above or below the Earth's surface. Intrusive rocks specifically form from magma that cools and solidifies underground, beneath the Earth's surface.
Is peridot an intrusive or extrusive igneous rock?
Peridot is olivine, which is a mineral, not a rock. It is found in both intrusive and extrusive rocks.
Can igneous rock be formed above or below ground?
Yes, igneous rocks can be formed both above and below the ground. When molten rock solidifies beneath the Earth's surface, it forms intrusive igneous rocks like granite. If molten rock reaches the Earth's surface and cools rapidly, it forms extrusive igneous rocks like basalt.
Is sandstone extrusive?
sedimentary rock are extrusive when the were formed outside land than in the dirt extrusive rocks take less time to form than intusive (formed under ground) becase wind and help it form faster. i hope this is very helpful =)
Is it true that igneous rocks form only beneath earths surface?
No, igneous rocks can form both beneath and above the Earth's surface. Intrusive igneous rocks form beneath the surface as magma cools and solidifies underground. Extrusive igneous rocks, on the other hand, form on the Earth's surface when lava cools and solidifies quickly.
Is igneouse rocks in the ground or above?
Igneous rocks can be found both in the ground and above ground. Igneous rocks form from the cooling and solidification of magma or lava, which can happen below the Earth's surface (intrusive igneous rocks) or on the surface (extrusive igneous rocks).
Is the rock olivine intrusive?
Olivene is a mineral, not a rock. It can be found in both intrusive and extrusive igneous rocks. The appearance of olivene is mainly controlled by the composition of the magma
