Yes, igneous rocks are formed through the crystallization of magma or lava. As the molten rock cools and solidifies, minerals within it begin to crystallize. This process results in the formation of igneous rocks with a crystalline structure.
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.
Both glass formation and the formation of igneous rocks involve the cooling of molten material, which results in the solidification of the material into a solid state. In both processes, rapid cooling can prevent the formation of crystalline structures, resulting in an amorphous or glassy material. However, in the formation of igneous rocks, there is typically more time for crystal formation to occur compared to the rapid cooling of glass formation.

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.

Cementing is not a process involved in the formation of sedimentary rock.
Metamorphic rocks can form from both igneous and sedimentary rocks through the process of heat and pressure, but they are more commonly associated with forming from existing metamorphic or sedimentary rocks. Igneous rocks can indirectly contribute to the formation of metamorphic rocks by heating up and altering surrounding rocks, leading to the formation of new metamorphic rocks.
"Igneous rocks (etymology from Latin ignis, fire) are rocks formed by solidification of cooled magma (molten rock)" ~Wikipedia.comSee Related Links below.
Igneous rocks are formed in and around volcanos, metamorphic rocks are formed by the partial melting of rocks deep underground.

The rock cycle begins with the formation of igneous rocks through the cooling and solidification of magma or lava. These rocks can then be weathered and eroded into sediment, which can be compacted and cemented to form sedimentary rocks. These rocks can then be subjected to heat and pressure to become metamorphic rocks. This continuous process of formation, erosion, and transformation of rocks is known as the rock cycle, and it impacts the formation of different types of rocks by providing the necessary conditions for their creation and transformation.

An example of magmatism is the formation of igneous rocks from the cooling and solidification of molten magma beneath the Earth's surface. This process can lead to the creation of various types of igneous rocks such as granite, basalt, and obsidian.
Igneous rocks vary greatly in composition and method of formation, resulting in diverse densities.
