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.

∙ 9y agoVarious types of igneous rocks are created from volcanic eruptions. Magma can create Basalt, Andesite, and Rhyolite rocks. The different types are formed based on the elements present and the temperature at the time of contact.

Are all rocks formed by volcanoes?
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
What rock would most likely be found near a volcano?
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
What rocks are from volcanoes?
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.
What stone can float on water?
Pumice stones will, these are low density rocks formed by volcanoes
How did igneous rocks form?
An igneous rock is formed when lava cools and hardens.

What did chemist learn about the mons surface by analyzing moon rocks?
The rocks were similar to rocks formed by volcanoes on Earth, suggesting that vast oceans of molten lava once covered the moon's surface.
What kinds of rock are formed by volcanoes?
Extrusive igneous rocks are formed from the solidification of magma above ground.

Which rocks formed from hardened lava that flowed from volcanoes?
extrusive igneous rock
