Rocks formed by crystallization from a melt (magma).
The effect of temperature in the formation of igneous rocks is crucial, as it determines the melting of magma and the crystallization of minerals. Higher temperatures facilitate the melting of solid rock into magma, while cooling temperatures lead to the crystallization of minerals as the magma solidifies. The specific temperature at which this occurs influences the rock's texture, mineral composition, and overall characteristics. Typically, the formation of igneous rocks occurs at temperatures ranging from around 700°C to 1300°C.
Volcanoes arise primarily through the movement of tectonic plates and the melting of Earth's mantle. When tectonic plates diverge or converge, magma can rise to the surface, forming a volcano. This process is often accompanied by volcanic activity such as eruptions, which can release gases and lava. Additionally, hotspots, where mantle plumes create localized melting, can also lead to volcano formation away from tectonic plate boundaries.
Clastic sedimentary rocks are formed by the weathering, erosion, deposition, compaction and cementation of other rocks. Chemical sedimentary rocks however may be precipitated directly from saturated solutions (examples incldue the evaporitic rocks and certain types of carbonates such as oolitic limestones). Some other sedimentary rocks may be biogenic in origin (such as the linmestones that are formed of coral reefs).

Because sedimentery rock is formed under the sea, sediment collects at the bottom of the ocean, and so does a few dead sea creatures, then t gets squashed by other sediment, igneous rock is formed by lava cooling, so there is no fossils in it.
Melting and solidification!
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.
Igneous rock forms when magma cools and solidifies either beneath the Earth's surface (intrusive) or when lava cools and solidifies at the surface (extrusive). Cooling rate, mineral composition, and the amount of gas present in the magma all influence the type of igneous rock that forms.
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.
Yes, heat can cause rocks to melt and form new rocks through the process of melting, cooling, and solidifying. This can lead to the formation of igneous rocks from both existing rocks and molten rock material.
The process that changes sedimentary rock into igneous rock is called "melting." When sedimentary rock is subjected to high temperatures and pressures deep within the Earth's crust, it can melt and re-crystallize into igneous rock. This process occurs in the presence of magma and can lead to the formation of new igneous rock.
A faster rate of cooling typically results in the formation of finer-grained igneous rocks, such as basalt or rhyolite. Slower cooling allows for larger mineral crystals to form, resulting in coarser-grained rocks like granite or diorite. Rapid cooling at the Earth's surface can also lead to the formation of volcanic glass.

Igneous rocks will develop large crystals is they cool slowly underground.
Because that is the very definition of igneous rock.
Igneous rocks will develop large crystals is they cool slowly underground.
The process of melting rocks creates magma, which is a molten mixture of minerals and gases. When this magma cools and solidifies, it can form igneous rocks. Additionally, the melting of rocks can also lead to the formation of various minerals and contribute to geological processes such as volcanic eruptions and the creation of new landforms.
