There are two types of igneous rocks; intrusive and extrusive. Intrusive igneous rocks are formed underneath the earth's surface from magma where it cools slower and develops large crystal structures. Extrusive igneous rocks are formed above the earth's surface from lava that cools quickly and creates rocks with smaller, finer crystal structures.
What else can I help you with?
Igneous rocks are classified based upon their composition and what?
Igneous rocks are classified based on their composition and texture. Composition is determined by the minerals present, while texture refers to the size of the mineral grains in the rock. These classifications help geologists understand the conditions under which the rock formed.
Igneous rocks are classified based upon their what?
Igneous rocks are classified based on their mineral composition, texture, and formation process. The minerals present in the rock, the size of the grains, and whether the rock formed beneath the Earth's surface (intrusive) or on the surface (extrusive) are key factors in classification.
When a sedimentary rock melts and solidifies what rock forms?
When a sedimentary rock melts, it forms an igneous rock upon solidification. This process involves the sedimentary rock going through changes in temperature and pressure, causing it to melt and re-crystallize into an igneous rock.
Igneous rocks are classified based upon their mineral composition and?
And their texture, which can be aphanitic, phaneritic, glassy, or porphyritic. mineral composition and crystal texture
What are the 3 major classifications of rock?
Igneous, metamorphic and sedimentary.
what are igneous rock classified based upon?
Igneous rocks can be classified by their method of formation and by their mineralogy.

When a sedimentary rock melts, it forms an igneous rock upon solidification. This process involves the sedimentary rock going through changes in temperature and pressure, causing it to melt and re-crystallize into an igneous rock.
Can Sedimentary rock cannot change into igneous rock?
Sedimentary rock can change into igneous rock, but not directly. The process involves first transforming sedimentary rock into metamorphic rock through heat and pressure. Then, if the metamorphic rock melts, it can become magma, which, upon cooling, crystallizes into igneous rock. Thus, while sedimentary rock does not directly become igneous rock, it can ultimately contribute to the formation of igneous rock through these intermediate steps.
Why are fossils found in sedimentary rock but not igneous rock?
Igneous rock forms from magma or lava. It would be unlikely an organism's remains would survive partially or intact upon exposure to such conditions.
Igneous rocks are classified based upon their mineral composition and?
And their texture, which can be aphanitic, phaneritic, glassy, or porphyritic. mineral composition and crystal texture
What are animals classified on?
Animals are classified based upon their anatomy, physiology, genetics and behaviors.
Is bryce canyon igneous sedimentary or metamorphic rock?
All three types of rock exist at Bryce. It depends upon where you are in the park.
Can the structure of composition of igneous or volcanic rocks be changed or altered significantly if at all upon their ejection from a volcano?
Yes, the structure of composition of either a volcanic or igneous rock can be altered significantly upon their ejection from a volcano.
What are the 3 major classifications of rock?
Igneous, metamorphic and sedimentary.
What formation of igneous rock on earth's surface is known as?
The formation of igneous rock on Earth's surface is known as volcanic or extrusive igneous rock. This type of rock forms when magma erupts from a volcano and cools quickly upon exposure to the Earth's atmosphere or ocean water, resulting in fine-grained textures. Common examples include basalt and pumice.
