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
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.
Pumice stones will, these are low density rocks formed by volcanoes
Igneous rocks are rocks formed by magma. so the best place to find igneous rocks would be by volcanoes or where a volcano once erupted.
Three different types of volcanoes are 1) Shield volcanoes; they are large mountains with gentle slopes. 2) Cinder cones volcanoes; they are small volcanoes made of hardened lava chunks called cinders. And the last one is 3) composite volcanoes; they are medium sized mountains made up of layers of lava that alternates with cinders. That is it.
Hawaii Volcanoes National Park is known for having basaltic rocks, including basaltic lava flows, cinders, and ash. These rocks are primarily formed from the eruptions of the shield volcanoes in the park, such as Mauna Loa and Kilauea.
Rocks formed in volcanoes from magma.
they are formed wherever active volcanoes are

Volcanoes.
Volcanoes can produce different types of rocks, including igneous rocks like basalt, andesite, and rhyolite. These rocks are formed from magma that cools and solidifies either within the volcano (intrusive) or on the surface (extrusive) through processes like volcanic eruptions.
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.

Obsidian is black glass formed by volcanoes.
From lava that came from volcanoes. They harden to form igneous rocks.
