Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.

What type of rock forms because of heating and melting followed by cooling?
Igneous rock forms due to the heating and melting of pre-existing rocks, followed by cooling and solidification of the molten material, known as magma or lava. When this process occurs beneath the Earth's surface, it creates intrusive igneous rocks, while cooling at the surface results in extrusive igneous rocks. Examples include granite (intrusive) and basalt (extrusive).
What is granite bedrock?
Granite bedrock is a type of bedrock composed mainly of quartz, feldspar, and mica minerals. It is a common type of igneous rock that forms from the cooling and solidification of magma deep within the Earth's crust. Granite bedrock is known for its durability and often used in construction due to its strength and resistance to weathering.
How is the size of crystals in an igneous rock related to the formation of a rock?
If an igneous rock is formed from slowly cooling magma under the ground, it has more time to form crystals and so the crystals it forms are much larger than igneous rock formed from more quickly cooling magma or lava.
What is the most common type of intrusive rock?
The most common type of intrusive rock is granite. Granite forms from the slow cooling of magma deep underground, resulting in a coarse-grained texture with visible crystals of minerals such as quartz, feldspar, and mica. It is widely distributed on Earth's continental crust and often used in construction and sculpture due to its durability.
Smooth glassy rock that is formed when lava cools?
Obsidian
What type of rock forms due to heating and cooling?
Sedimentary rock forms due to the accumulation and compression of sediments, while metamorphic rock forms due to the alteration of existing rock through heat and pressure. Igneous rock forms from the cooling and solidification of magma or lava.
Which type of rock forms due to weight of the overlying rocks?
Metamorphic
Igneous rock definition?
Rocks formed by the cooling and solidifying of molten materials.
What type of rock is formed as a result of lava cooling quickly?
The type of rock formed from lava cooling quickly is called basalt. Basalt is a fine-grained igneous rock that is commonly found in volcanic regions and has a dark color due to its rapid cooling process.
Which type of rock forms due to the weight of the overlying rocks?
Sedimentary rock forms due to the weight of overlying sediments, which compress and cement together over time.
What type of rock forms at the boundary of magma and rock?
Contact metamorphic rock forms at such boundaries, as the minerals in the rock change due to the increase in temperature or the influx of heated fluids.
What is granite bedrock?
Granite bedrock is a type of bedrock composed mainly of quartz, feldspar, and mica minerals. It is a common type of igneous rock that forms from the cooling and solidification of magma deep within the Earth's crust. Granite bedrock is known for its durability and often used in construction due to its strength and resistance to weathering.
Is basalt a metamorphic rock?
No, basalt is not a metamorphic rock. Basalt is an igneous rock that forms from cooling and solidification of lava. Metamorphic rocks are formed from the alteration of existing rocks due to high pressure, heat, or fluids.
What is the name given to the volcanic glass that forms due to very rapid cooling of magma?
Yes obsidian is glassy because it cooled very fast.
What kind of rock is pegmatite is it sedimentary igneous or metamorphic?
Pegmatite is an igneous rock that forms in the final stage of magma crystallization. It typically contains large crystals due to the slow cooling of the magma.
Which type of rock is formed as a result of lava cooling quickly?
Igneous rock, specifically basalt, is formed when lava cools quickly. Basalt is characterized by its fine-grained texture due to rapid cooling at the Earth's surface.
How is the size of crystals in an igneous rock related to the formation of a rock?
If an igneous rock is formed from slowly cooling magma under the ground, it has more time to form crystals and so the crystals it forms are much larger than igneous rock formed from more quickly cooling magma or lava.
