Pumice and obsidian. There are others but these two are the most common. It also depends the type of volano and the geology of the area in which the volcano forms.
When lava reaches the surface of the Earth through volcanoes or through great fissures the rocks that are formed from the lava cooling and hardening are called extrusive igneous rocks. Some of the more common types of extrusive igneous rocks are lava rocks, cinders, pumice, obsidian , and volcanic ash and dust
Around a volcano that has erupted recently, you would find volcanic rocks such as basalt, andesite, and rhyolite. These rocks are formed from cooled lava and ash that are ejected during volcanic eruptions. In some cases, you may also find volcanic glass or obsidian near the eruption site.
When lava cools, it forms what is known as an extrusive igneous rock. Volcanoes are also associated with alteration from heat and fluids. Therefore you would expect to find extrusive rocks as well as altered rocks.
Those would be igneous rocks. Extrusive igneous rocks.
Tuff, which is composed of volcanic ash that has been compacted and cemented together, would be commonly found near a volcano. Ash flows, volcanic breccias, and lahars are other types of sedimentary rocks that may also be found in volcanic regions.

If there is liquid in volcanic rocks, it would most likely be water.

Volcanic rocks are considered igneous.

you would find it in various different places on the volcano. there are also various different types of igneous rock, that there is on the volcano. like my answer? you don't have to use it but it would be good if you did
Pangaea was a supercontinent that existed around 335 million years ago. Volcanic rocks in Pangaea would have been formed by volcanic activity at the time, likely exhibiting characteristics such as basaltic composition, vesicular texture, and presence of minerals like olivine and pyroxene. These rocks would have contributed to the geology and formation of Pangaea.
Volcanic activity in the past deposited volcanic rocks in the region as the Indian plate collided with the Eurasian plate, forming the Himalayas. These volcanic rocks are eventually uplifted and exposed due to the tectonic forces that shape the Himalayan mountain range.
You would find extrusive igneous rocks. Beyond that it depends on the volcano.
Yes. Rocks are defined as combinations of minerals. The only exception to this would be some volcanic rocks that are composed mostly of glass.
