What is the major difference between igneous and metamorphic rocks? Report Abuse. Igneous rocks are crystalline solids which form directly from the cooling of magma.The chemistry of the parent rock largely determines the composition of the resulting metamorphic rock. So the major difference is that Igneous rocks are made from magna and metamorphic rock is made from any other rock.hen magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground. Metamorphic rocks are rocks that have morphed into another kind of rock.

Difference Between Basalt and Granite Basalt is an extrusive igneous rock, whereas granite is an intrusive ingenuous rock. Those who do not know, extrusive rocks are those formed of lava coming out of volcanoes, whereas rocks formed of magma that has yet not come out of the volcano are termed as intrusive rocks. Basalt is darker and is composed of magnesium and iron, whereas granite is lighter and is made up of feldspar and quartz. • Basalt is called mafic, while granite is called felsic. • Basalt splits along columnar planes, while granite splits along horizontal planes.

Comparing Igneous, Sedimentary and Metamorphic Rocks. Igneous rocks are formed when magma or lava cools and hardens. An igneous rock becomes a sedimentary rock through weathering and erosion of the igneous rock. The igneous rock, exposed to weathering processes at the surface, breaks into smaller pieces.etamorphism is the change in form of a geological unit (like a rock) through metamorphic processes (must be in solid state). These processes include temperature and pressure changes as well as chemical changes. A sedimentary rock can be transformed into an igneous rock and then into a metamorphic.

Igneous Rocks Igneous Rocks. Igneous rocks are formed from lava or magma. Magma is molten rock that is underground and lava is molten rock that erupts out on the surface. The two main types of igneous rocks are plutonic rocks and volcanic rocks. Plutonic rocks are formed when magma cools and solidifies underground.Volcanic rocks are formed from lava that flows on the surface of the Earth and other planets and then cools and solidifies. The texture of an igneous rock depends on the size of the crystals in the rock.hen magma cools underground, it cools very slowly and when lava cools above ground, it cools quickly. When magma and lava cool, mineral crystals start to form in the molten rock. Plutonic rocks, which cool slowly underground, have large crystals because the crystals had enough time to grow to a large size.

Igneous rock Igneous rock (derived from the Latin word ignis meaning fire) is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.

- An Igneous rock is the product of cooled solidified magma/lava. As magma/lava cools it goes through the process of crystallization which turns it into an igneous rock. The amount of time it takes for an igneous rock to form depends on its location and its composition.There are two types of igneous rocks; Extrusive and Intrusive.n the other hand an Intrusive igneous rock cools very slowly beneath the surface and is created by magma. Since the cooling process is very slow intrusive igneous rocks have very large crystals (coarse grained). In some instances there is also a third type of igneous rock.

Difference Between Igneous, Sedimentary and Metamorphic Rocks Igneous, Sedimentary vs Metamorphic Rocks. The main difference between Igneous, Sedimentary and Metamorphic rocks, is the way that they are formed, and their various textures.Igneous Rocks. Igneous rocks are formed when magma (or molten rocks) cool down, and become solid.xamples of these types of rocks include slate, gneiss, marble, and quartzite, which occurs when re-crystallization changes the shape and form of an original rock formation. Summary: 1.Igneous rocks are formed when magma (or molten rocks) have cooled down and solidified.

What changes a metamorphic rock into an igneous rock? A metamorphic rock cannot change into a igneous rock. A igneous rock is formed when magma solidifies into a solid state. A metamorphic rock is formed when another rock experiences extreme pressure under the earths crust. You cannot change a metamorphic rock back into a igneous one it is the other way around.

Metamorphic Rocks Lesson #14 Dynamic Metamorphism also occurs because of mountain-building. These huge forces of heat and pressure cause the rocks to be bent, folded, crushed, flattened, and sheared. Metamorphic rocks are almost always harder than sedimentary rocks. They are generally as hard and sometimes harder than igneous rocks. They form the roots of many mountain chains and are exposed to the surface after the softer outer layers of rocks are eroded away.

The Basics of Rocks and Minerals and Polar Geology Igneous rocks form when magma or lava cools and hardens into a rock. Magma and lava are rocks that are so hot they move like a liquid. Magma is molten rock that is underground; lava is molten rock that is above the ground – and that is the only difference between them.

About Igneous Rocks The two best-known igneous rock types are basalt and granite, which have distinctly different compositions and textures. Basalt is the dark, fine-grained stuff of many lava flows and magma intrusions. Its dark minerals are rich in magnesium (Mg) and iron (Fe), hence basalt is called a mafic rock.ranite is the light, coarse-grained rock formed at depth and exposed after deep erosion. It is rich in feldspar and quartz (silica) and hence is called a felsic rock. So granite is felsic and plutonic. Basalt and granite account for the great majority of igneous rocks.

- Lesson Summary. All three rock types-igneous, sedimentary, and metamorphic-make up a portion of the rock cycle. Igneous rocks are rocks that formed directly from magma and can form either in the earth or on its surface.n certain conditions, igneous or sedimentary rocks can be changed into different rocks under intense heat and pressure. These rocks literally change into new substances very different from their old ones. This usually happens as rocks are buried deep within the crust. One of the most common metamorphic rocks is marble.

Igneous Rocks Igneous Rocks. Igneous rocks are formed from lava or magma. Magma is molten rock that is underground and lava is molten rock that erupts out on the surface. The two main types of igneous rocks are plutonic rocks and volcanic rocks. Plutonic rocks are formed when magma cools and solidifies underground.Volcanic rocks are formed from lava that flows on the surface of the Earth and other planets and then cools and solidifies. 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. When magma and lava cool, mineral crystals start to form in the molten rock.Plutonic rocks, which cool slowly underground, have large crystals because the crystals had enough time to grow to a large size.hen magma cools underground, it cools very slowly and when lava cools above ground, it cools quickly.

Intrusive & Extrusive Igneous Rocks Review When magma cools either above or underground, igneous rock is formed. What is the difference between intrusive and extrusive igneous rocks? Since Intrusive igneous rocks were formed underground, they had more time to release air and the size of the crystals is bigger. Extrusive rocks cool quickly so they don't have much time to compress together with all the crystals.

Metamorphic Rocks Lesson #14 Igneous rocks form when rocks are heated to the melting point which forms magma. Sedimentary rocks are formed from the cementing together of sediments, or from the compaction (squeezing together) of sediments, or from the recrystallization of new mineral grains which are larger than the original crystals.chists are usually named by the main minerals that they are formed from. Bitotite mica schist, hornblende schist, garnet mica schist, and talc schist are some examples of this. Gneiss is a high grade metamorphic rock. This means that gneiss has been subjected to more heat and pressure than schist.
