The answer strongly depends on the kind of igneous rock and other local conditions. There are many kinds of igneous rock, and too many variables to give a simple answer to an overly-simple question.
molten rock because it sturdy and it can keep your fire burning;)
Niether. Volcanic rock is a mixture.
A slab of volcanic rock is called a "lava flow" or a "lava rock".
Old Fort, also known as the Fort San Cristóbal in Puerto Rico, was built using a common type of volcanic rock called "tuff." Tuff is a type of rock formed from consolidated volcanic ash ejected from vents during a volcanic eruption. It is a durable and easily workable material, making it suitable for construction purposes.
Magma, (Volcanic Rock)
molten rock because it sturdy and it can keep your fire burning;)
moving of tectonic plates and the build up of pressure within the volcanic mountain under the dried up lava which became rock after the previous volcanic eruption
No. Volcanic rock is not flammable.
Volcanic islands are formed by volcanoes and are therefore composed of volcanic rock.
Niether. Volcanic rock is a mixture.
Kimberlite is a volcanic rock. Kenyte is a volcanic rock found on Mount Kenya.
It is fairly easy to determine the age of lava or volcanic ash using radiometric dating, but much harder with sedimentary rock. But, if a layer of sedimentary rock is in between two layers of volcanic rock, then we know if had to have formed after the first layer and before the second one. If we know how old the volcanic layers are, then we have a general idea of how old the sedimentary layer is as well.
Yes, pumice is a volcanic rock that is formed from the solidification of frothy volcanic lava. It is known for its porous and lightweight nature, making it float on water.
Volcanic rock forms by lava that has come from a volcano, cools and solidifies to form the rock.
A slab of volcanic rock is called a "lava flow" or a "lava rock".
Volcanic rock.
No. Obsidian is just one of many types of volcanic rock.
