Melting and Solidification
Processes such as melting, recrystallization, and metamorphism occur deep in the Earth's crust. These processes involve high temperatures and pressures that cause rocks to change their form and composition.
At a convergent boundary, the processes of subduction, where one tectonic plate is forced beneath another, can lead to the formation of metamorphic rocks such as schist and gneiss. Additionally, the intense heat and pressure generated by the collision of two plates can cause the melting of rocks, leading to the formation of igneous rocks like granite.
Igneous rocks are formed through two processes: cooling and solidification of molten rock (magma) on or beneath the Earth's surface (extrusive), and cooling and crystallization of magma deep beneath the Earth's surface (intrusive).
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.
Other types of rocks include volcanic rocks (such as basalt and pumice), hydrothermal rocks (like geyserite and travertine), and organic rocks (such as coal and limestone). These rocks form from specific processes or conditions that differ from the formation of igneous, sedimentary, and metamorphic rocks.

No. Heat from the interior of the Earth trying to reach the surface drives lithospheric plate movements which are mostly responsible for the formation of igneous and metamorphic rocks.

Igneous rocks are formed as the result of cooling magmas.
Igneous rocks are formed in and around volcanos, metamorphic rocks are formed by the partial melting of rocks deep underground.

Rocks are typically classified into three main families: igneous, sedimentary, and metamorphic. Igneous rocks form from the solidification of molten material, sedimentary rocks are created from the accumulation and compaction of mineral and organic particles, and metamorphic rocks result from the alteration of existing rocks due to heat, pressure, or chemically active fluids. Each family encompasses various types of rocks with distinct characteristics and formation processes.
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.
