Is Scoria rock igneous?
Yes,Scoria (a type of Basalt) Basalt is a dark-colored rock that formed as lava cooled and hardened. Scoria is a type of basalt that's full of bubble holes. The bubbles formed as the lava was blasted out of a volcano, and were trapped as the lava cooled and hardened.
How do tower hill volcano look like?
It looks like a group of scoria volcanoes that are in a circle and a maar crater in the center
What rock is formed when a volcano explodes?
An andesite rock. it came out of the volcanic eruption of Mt. St. Helens...
What is tephra?
Tephra is produced naturally by volcanic eruptions and refers to the material produced when the volcano erupts. Tephra comes in a range of forms and are classified by size Ash, Lapilli or Volcanic blocks.
Are basaltic scoria and scoria the same thing?
Not necessarily. Most scoria is basaltic, but some can be andesitic.
How is scoria created?
Scoria is a frothy form of lava ejected from a volcano as individual pieces.
Why doesn't granite have air holes like pumice and scoria?
Pumice and scoria are volcanic rock. They form form the lava the erupts from the volcano and contains bubbles from gasses. These bubbles cause the cavities you're calling air holes.
Is scoria a granite rock?
No. Scoria is a basaltic lava ejected as fragments from a volcano, typically with a frothy texture.
Granite pumica and scoria are igneous rocks Why doesnt granite air have airholes like the other two?
it is because granite is formed by magma that cools under the earth unlike pumica and scoria that form while a volcano erupts.
Is scoria a mineral?
Scoria is a textural rock type and not a rock that is classified by mineralogy or chemistry. It forms from lava that is rich in volatiles or gases but is less viscous than apumiceforming lava. When the molten rock is rising in the volcanic pipe, gases begin to form and collect and those gases form large bubbles in the lava. The resulting solidified rock is scoria. Although the open spaces in scoria can be large the rock is generally heavier than water, unlike most pumice which can float on water.Some scoria forms from lavas that flow out of a volcano and some scoria can be pyroclastic. Pyroclastic rocks form from lava that is ejected from the volcano. Scoria (which is also known as cinder) is the primary component of cinder cones. A cinder cone is a small but very common volcano type. Cinder cones have also been called scoria cones. Cinder cones rarely grow very large, but form sometimes very symmetrical cone-shaped hills.Scoria does not have a lot of uses. In fact the name is derived from a term for waste. However it can be used as an interesting decorative stone with some reddish color. Some of the large Easter Island statues called Moai have scoria stone in their designs.

How did volcano Kos form?
Kos hasn't any volcano.
What is formed by explosive eruptions by a volcano?
Explosive eruptions will produce pyroclastic rocks such as scoria, pumice, and tuff.

What kind of volcano is formed after a volcano erupts?
Any kind of volcano can form after the eruption. If it doesn't erupt and never has then it isn't a volcano.
Why doesnt granite have airholes like pumice and scoria?
Pumice and scoria are both extrusive igneous rocks that form when molten rock is ejected from a volcano. In both cases gasses trapped in the magma are released, forming bubbles. Granite, by contrast, is an intrusive rock that forms when molten rock cools deep underground without erupting from a volcano. The magma is under great pressure so that gasses cannot be released. Instead they become part of the mineral structure of the newly form rock.
