no not all rocks are formed by volcanoes because what about sedimentary rocks which are the rocks formed over a long period of time by little pieces of sand and rock etc. by wind and water
Rocks found by volcanoes are formed from lava and magma inside and outside the volcano. Rocks found along beaches are formed all kinds of different ways. It all depends on how the rock is formed
Igneous rock is the type of rock most commonly formed from volcanoes. igneous rocks may be formed from the magma underground, or form after the magma has ejected into the air. Underground, they can be formed when magma (molten rock) is trapped in small pockets and cools slowly over time. Above ground, igneous rocks are formed as the lava cools. Metamorphic rocks can be the result of volcanic activity, but they are not formed directly from volcanoes. Metamorphic rocks are the result of intense heat or extreme pressure transforming either sedimentary or igneous rocks, and these stresses can come from volcanic action, though that is not always the case.
all volcanoes are made of rocks
Pumice stones will, these are low density rocks formed by volcanoes
An igneous rock is formed when lava cools and hardens.
Rocks formed in volcanoes from magma.
they are formed wherever active volcanoes are
Volcanoes form igneous rock.

Volcanoes.
Volcanoes.
The rocks were similar to rocks formed by volcanoes on Earth, suggesting that vast oceans of molten lava once covered the moon's surface.
Extrusive igneous rocks are formed from the solidification of magma above ground.
extrusive igneous rock
From lava that came from volcanoes. They harden to form igneous rocks.
Obsidian is black glass formed by volcanoes.
