Why don't igneous rocks look like magma rocks if igneous rock is formed from magma?
Because that is the very definition of igneous rock.
Is it generally true that igneous rocks are formed by the crystallization of molten magma?
Yes, it is generally true that igneous rocks are formed by the crystallization of molten magma. When magma cools and solidifies, it can form intrusive igneous rocks, such as granite, if it cools slowly beneath the Earth's surface. Conversely, if magma erupts as lava and cools quickly on the surface, it forms extrusive igneous rocks, like basalt. This process of crystallization is fundamental to the formation of all igneous rocks.
What does magma have to do with igneous rocks?
Magma is molten rock beneath the Earth's surface. When magma cools and solidifies, it forms igneous rocks. The cooling process can occur either slowly beneath the surface (intrusive igneous rocks) or rapidly on the surface (extrusive igneous rocks).
Igneous rocks were formed from what minerals?
Igneous rocks are formed from minerals such as quartz, feldspar, pyroxene, and olivine. These minerals solidify from magma or lava as it cools and hardens, resulting in the formation of igneous rocks.
Is rock formed when hot magma cools and hardens?
No, rocks are formed when molten magma or lava cools and solidifies. This process can occur underground (intrusive igneous rocks) or on the Earth's surface (extrusive igneous rocks), leading to the formation of various types of rocks.
Is erosion a necessary for the formation of igneous rocks?
No, erosion is not necessary for the formation of igneous rocks. Igneous rocks are formed from the cooling and solidification of magma or lava, which can occur below the Earth's surface or on the surface. Erosion can affect igneous rocks once they have been formed by breaking them down and transporting the sediments.
Why don't igneous rocks look like magma rocks if igneous rock is formed from magma?
Because that is the very definition of igneous rock.
Which two processes result in the formation of igneous rocks?
The two processes that result in the formation of igneous rocks are cooling and solidification of molten magma, and crystallization of magma within the Earth's crust or on the surface. These processes lead to the solidification of molten material, which then forms igneous rocks.

How do melting and cooling lead to igneous rock formation?
Rocks formed by crystallization from a melt (magma).
Magma cools and solidifies to form what rocks?
igneous rocks
What process is involved in the formation of all igneous rocks but not in the formation of metamorphic rocks?
mountain building
Which is the best explanation for the formation of igneous rock?
"Igneous rocks (etymology from Latin ignis, fire) are rocks formed by solidification of cooled magma (molten rock)" ~Wikipedia.comSee Related Links below.
What does magma have to do with igneous rocks?
Magma is molten rock beneath the Earth's surface. When magma cools and solidifies, it forms igneous rocks. The cooling process can occur either slowly beneath the surface (intrusive igneous rocks) or rapidly on the surface (extrusive igneous rocks).
What is one cause of volcanic activity and igneous rock formation?
Igneous rocks are called fire rocks and are formed either underground or above ground. Underground, they are formed when the melted rock, called magma, deep within the earth becomes trapped in small pockets. As these pockets of magma cool slowly underground, the magma becomes igneous rocks. Igneous rocks are also formed when volcanoes erupt, causing the magma to rise above the earth's surface. When magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground.
Igneous rocks were formed from what minerals?
Igneous rocks are formed from minerals such as quartz, feldspar, pyroxene, and olivine. These minerals solidify from magma or lava as it cools and hardens, resulting in the formation of igneous rocks.
