Which type of rock comes out of a volcano as lava the cools?
When lava cools and solidifies, it forms igneous rock. The specific type of igneous rock that forms from lava is called extrusive or volcanic rock, which includes examples like basalt and pumice. These rocks typically have a fine-grained texture due to the rapid cooling of lava on the Earth's surface.
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 rock cools on the Earth's surface?
Igneous rocks cool on the Earth's surface. When molten rock, or lava, erupts from a volcano and solidifies, it forms volcanic rock, a type of igneous rock. Common examples include basalt and pumice, which are characterized by their fine-grained texture due to rapid cooling.
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 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.

Igneous rock definition?
Rocks formed by the cooling and solidifying of molten materials.
Which type of rock forms due to weight of the overlying rocks?
Metamorphic
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.

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.
