Is AAA a form of volcanic rock?
AAA is nothing in relation to volcanoes. A'a is a variety of volcanic rock, formed from a basaltic lava flow with a jagged surface.
Volcanic rock forms by lava that has come from a volcano, cools and solidifies to form the rock.
Mafic Magma forms volcanic rock.
volcanic - it is made form volcanic ash that has solidified.
Volcanic glass is considered an extrusive rock because it can form above the earth's surface.
volcanic mountains form when molten rock erupts onto earth
igneous rock answ2. Volcanic bombs, volcanic ash, pumice, ignimbrite.
during a violent volcanic interuption
Obsidian is a naturally occurring volcanic form of glass.
Igneous rock is made up of volcanic rock that is cooled after flowing as lava. Much of this type of rock is made up of sulphur and iron. Crystals also form from this type of melting.
No. Igneous rocks can be divided into two general categories: intrusive and extrusive. Intrusive rocks form from magma that cools underground. Extrusive rocks are volcanic; they form from material that cools after being erupted.
rapid cooling, so that crystals do not form.
No. Volcanic rock is extrusive igneous rock, which cools at or above earth's surface. However, igneous rocks can form from magama that cools inside the earth as well. This is called intrusive igneous rock, sometimes called plutonic rock.
Obsidian, because it has cooled too quickly for crystals to form.
Plutonic rock is formed from magma in the Earth's crust. Volcanic rocks form from lava above ground.
Shiprock is comprised of a form of magma known as volcanic breccia.
Yes,it is a volcanic rock.
Basalt is an extrusive, volcanic rock. It commonly forms the volcanic mountains found in the Oceans - eg Hawaii is made of basalts.
the can form volcanic activity ... to be continuded
Dacite is a type of volcanic rock that can form from lava flows or pyroclastic deposits.
Igneous: Released in volcanic eruptions Sedimentary: Can form from erosion Metamorphic: Form due to high heat and pressure
Volcanic islands are formed by volcanoes and are therefore composed of volcanic rock.
An andesite rock. it came out of the volcanic eruption of Mt. St. Helens...
No. Volcanic rock is not flammable.
Volcanic rock is extrusive.
Pumice is considered special because it contains volcanic glass. It is a powdered or dust form of volcanic rock and the way pumice is formed is very unique.
Because pumice is primarily vesicular volcanic glass, it contains no minerals. The ejected molten volcanic rock cooled too quickly for minerals to form. Chemically, it is similar to felsic rock, high in silicon and aluminum.
Pahoehoe and a'a have essentially the same composition. They both cool to form a kind of rock called basalt.
Extrusive igneous rock forms from solidifying lava.
Volcanic rock is extrusive igneous rock. Plutonic rock is intrusive igneous rock.
Niether. Volcanic rock is a mixture.
Fossils usually form when the remains of an organism are buried gently under sediments which later turn into stone. Intrusive igneous rocks form at depths within Earth where no life is found. Extrusive igneous (volcanic) rocks are so hot when they are deposited that any remains of organisms are usually incinerated. Fossils do occur in volcanic rocks, but very rarely.
All rock does not contain mineral crystals. Obsidian, or volcanic glass, in particular is a rock that has cooled so quickly from lava that mineral crystals were not able to form.
Intrusive igneous rock would form. Granite is an example. If the same magma that formed the granite had reached the surface through volcanic eruption, the extrusive igneous rock rhyolite would form.
Kimberlite is a volcanic rock. Kenyte is a volcanic rock found on Mount Kenya.
No a meteorite is from space and volcanic rock is from earth
Basalt is the most common volcanic rock.
Volcanic rock can be found on and near a volcano.
Volcanic and non-volcanic mountains are formed by different mechanisms. Volcanic mountains are essentially piles of material, such as ash and cooled lava, that has been erupted by a volcano. Most mountains, though, are not volcanic. There are a few ways that these can form. Some mountains, such as the Himalayas, are formed by colliding continents. When this happens, the Eaerth's crust essentially crumples, and mountain rangers are thrust up. Mountains can also form in areas… Read More
Volcanic ash forms during explosive volcanic eruptions when rapidly expanding gas blasts molten rock into droplets. The smalles droplets form tiny pices of glass that we call volcanic ash.
That varies widely between different types of volcanic rock. Obsidian or volcanic glass, is harder then pumice, but both are volcanic rocks.
Usually geothermal energy. Sometimes the heat from volcanic lava.
Obsidian, which is volcanic glass, is a good example.
· Kimberlite - a volcanic rock · Kenyte - a volcanic rock found on Mount Kenya
Common, hihgly porous types of volcanic rock are pumice and scoria.
The extrusive volcanic rock pumice can float on water. Other extrusive volcanic rocks are not so lucky.
Rock formed from volcanic ash is called tuff.
Volcanic rocks are considered igneous.
No. Obsidian is just one of many types of volcanic rock.
