When melted rock cools or hardens on or under earths surface it forms what kind of rock?

It forms an igneous rock. If it is within the Earth, then it is an intrusive igneous rock (e.g. granite) and if it is erupted onto Earth's surface then it is an extrusive igneous rock (e.g. basalt).


How does metamorphic rocks turn into a igneous rocks?

If it finds its way dowm into the earths crust through rock cycle and then is melted and mixes together to form molten magma, it could re-erupt to the earths surface and form an extrusive igneous rock or cool and solidify within the earths crust as an intrusive igneous rock.

Which rock is formed from melted minerals?

Igneous rock is formed from melted minerals that have solidified and cooled. This process can occur either beneath the Earth's surface, forming intrusive igneous rocks, or on the surface, leading to extrusive igneous rocks.


What type of igneous rock formed when melted rock reaches earths surface?

When melted rock reaches Earth's surface, it cools quickly and solidifies to form an extrusive igneous rock. This rapid cooling prevents large mineral crystals from forming, resulting in a fine-grained texture. Common examples include basalt and rhyolite.


What kind of rock is formed when melted minerals cool and harden?

Igneous rock is formed when melted minerals cool and harden. This process can happen either beneath the Earth's surface (intrusive igneous rock) or on the surface (extrusive igneous rock). Examples of igneous rocks include granite, basalt, and obsidian.
