Igneous rocks.
In rocks such as basalt, scoria, and pumice the holes are formed from gas bubbles that were escaping from the molten rock as it cooled.
Rocks that were formed when molten rock cooled down are called igneous rocks. This process occurs either beneath the Earth's surface, resulting in intrusive (or plutonic) igneous rocks, or on the surface after a volcanic eruption, leading to extrusive (or volcanic) igneous rocks. Common examples include granite for intrusive rocks and basalt for extrusive rocks. The texture and composition of igneous rocks can vary significantly based on the cooling rate and the mineral content of the molten rock.
Yes
There is no such thing as an "exclusive" rock. However, there are extrusive rocks. These are divisions of igneous rocks, or rocks that form from molten rock. Intrusive rocks form from molten rock that has cooled underground. They can also be called plutonic rocks. Extrusive rocks, also called volcanic rocks, form from molten rock that has formed at or above the surface.
A volcano is formed when the molten magma (lava) beneath the crust is forced to the surface. Volcanic rock is lava that has cooled.
a molten rock
Rocks that formed when molten rock cooled down are called igneous rocks. They can be classified into two main types: intrusive (or plutonic) rocks, which crystallize slowly beneath the Earth's surface, and extrusive (or volcanic) rocks, which solidify quickly at the surface. Common examples include granite for intrusive rocks and basalt for extrusive rocks. The cooling process allows minerals to crystallize, giving igneous rocks their distinctive textures and compositions.
That is correct.
Rocks formed from hot molten rock that has coold and hardened are called what?
Molten lava cooled and hardened
