what is the origin of igneous rock?
1. what is the origin of igneous rock?
Answer:
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. ... When lava comes out of a volcano and solidifies into extrusive igneous rock, also called volcanic, the rock cools very quickly.

2. how are igneous rocks classified based on their origin
Answer:
Explanation:
igneous rocks may be simply classified according to their chemical/mineral composition as felsic, intermediate, mafic, and ultramafic, and by texture or grain size: intrusive rocks are course grained (all crystals are visible to the naked eye) while extrusive rocks may be fine-grained (microscopic crystals) or glass
3. how are igneous rocks classified based on their origin?
Igneous rocks may be divided into two categories. Intrusive or plutonic rocks crystallize from magma beneath the earth's surface. Extrusive or volcanic rocks crystallize from lava at the earth's surface. ... In addition to texture, igneous rocks may are classified according to their chemical composition.

5. 1.What are the characteristics of intrusive igneous rocks? extrusive igneous rocks?2.How do intrusive igneous rocks form? extrusive igneous rocks?
Answer:
1.Summary
Intrusive igneous rocks cool from magma slowly because they are buried beneath the surface, so they have large crystals.
Extrusive igneous rocks cool from lava rapidly because they form at the surface, so they have small crystals.
Texture reflects how an igneous rock formed.
2.Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies. Intrusive Igneous Rocks: Intrusive, or plutonic, igneous rock forms when magma is trapped deep inside the Earth.

7. it is true that when parent rocks including igneous,sedimentary,and metamorphic rocks are exposed to heat and pressure,the original rock is transformed into a metamorphic rock.
Answer:
Sedimentary rocks form by breaking down other kinds of rocks into small particles and washing or blowing them away; metamorphic rocks form from other rocks and igneous rocks form by melting other rocks. Thus rocks are always changing form and are redistributted as part of a giant cycle of renewal
Explanation:
:)
8. what are the characteristics of intrusive igneous rocks and extrusive igneous rocks
Answer:
Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet.
9. 2. If a solidified lava contains 23% silica, the rock is classified as;A. Felsic, Intrusive Igneous RockC. Ultramafic, Extrusive Igneous RockB. Intermediate, Intrusive Igneous Rock D. Mafic, Extrusive Igneous Rock
Answer:
A is the correct answer
Explanation:
Igneous rock is formed through the cooling and solidification of magma or lava.
10. While it is clear that metamorphic and sedimentary rocks originated from igneous rocksthrough a number of processes, how can igneous rocks form from the sedimentary andmetamorphic rocks?
Answer:
Sedimentary rocks form by breaking down other kinds of rocks into small particles and washing or blowing them away; metamorphic rocks form from other rocks and igneous rocks form by melting other rocks.

12. Magma is the original material that make up igneous rocks. true or false
Answer:
TrueExplanation:
Yan po tamang sagot thanks me laterAnswer:
TRUE PO YES,
Explanation:
Sedimentary and igneous rocks began as something other than rock. Sedimentary rocks were originally sediments, which were compacted under high pressure. Igneous rocks formed when liquid magma or lava—magma that has emerged onto the surface of the Earth—cooled and hardened.
13. There are three kinds of rocks identified and these three have different origins. These are the igneous, sedimentary and the metamorphic rocks. About 65% of the earth’s crust is made up of igneous rocks; 27% is metamorphic and about 8% is sedimentary.
Answer:
rocks are classified into
•Igneous rocks that has a two type namely: extrusive igneous rocks and entrusive igneous rocks
•sedimentary rocks
that has a three types namely: chemical,organic,clastic
•Metamorphic rocks
that has atwo types namely non-foliated and foliated metamorphic rocks
14. EXTRUSIVE INTRUSIVE IGNEOUS ROCKS IGNEOUS ROCKS BOTH
Answer:
The two main categories of igneous rocks are extrusive and intrusive. Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet.
15. how are igneous rocks classified base on their origin??need po ang ans:ty
Answer:
Igneous rocks are classified on the basis of their composition or structure and their texture because there is a lot of diffirent kind of rocks.

26. you were given an igneous rock how would you tell if its volcanic or plutonic in origin
Answer:
The texture of an igneous rock depends on the size of the crystals in the rock. This tells us if the rock is plutonic or volcanic. When magma cools underground, it cools very slowly and when lava cools above ground, it cools quickly.
Explanation:
Answer: by deeply studying and knowing the rocks properties, many things can be done but that is the most common.
