You find a volcanic rock that is fairly smooth and only has a few small holes made when gas and water vapor escaped as the rock cooled you know that the rock can be classified as?

The rock described would be classified as an extrusive mafic igneous rock.

How much money is a volcanic rock worth?
Probably not that much, they are fairly common, although collectable.
What is volcano that erupts often?
Volcanic activity is classified by how often a volcano erupts. A volcano may be active, intermittent, dormant, or extinct.Active volcanoes erupt constantly.Intermittent volcanoes erupt fairly regularly.Dormant volcanoes are inactive, but not long enough to determine whether they will erupt again or not.Extinct volcanoes have been inactive since the beginning of recorded history.
Where is the most CO2 that has outgassed from Earth's volcanoes in the atmosphere escaped to space locked up in rocks?
Yes, volcanoes will emit about 0.15 - 0.25 gigatons of carbon annually in the present day.
What types of lava will most likely lead to a volcanic eruption of an effusive nature?
Shield volcanoes have effusive eruptions. Effusive eruptions are a volcanic phenomenon; in some ways the opposite of explosive eruptions. An effusive eruption is characterized by an outpouring of low viscosity lava which has a fairly low volatile content. Usually, shield volcanoes have effusive eruptions.
Why are Hawaiians volcanic eruptions less violent?
Compared with some other volcanoes around the world, the Hawaiian volcanoes are fed by low-viscosity magma with a low gas content. The explosive power of a volcanic eruption is driven by gas trapped in the magma, and magma that is more viscous allows more pressure to build up. The magma in the Hawaiian volcanoes flows out fairly readily.
Is there other land forms like Krakatoa?
Yes. Volcanic islands are fairly common.

Is volcanic acticity frequent?
It depends on the specific volcano. Some are fairly active, while others remain dormant.
Is sharm el sheikh classified as long?
it is fairly long - but not the longest - a place in New Zealand called Taumatawhakatangihangakoauauotamateapokaiwhenuakitanatahu
In which medium does light travel the slowest?
In some fairly recent experiments physicists have claimed to able to stop light entirely in super-cooled sodium.

Why doesn't pumice or obsidian turn into a metamorphic rock?
Pumice and obsidian are both forms of volcanic glass, which weathers away fairly easily.
What is the history of Hawaii land formation?
The islands that make up Hawaii are created by volcanic activity. Some of the volcanoes are now dormant but there is at least one volcano that is still considered active and has "erupted" fairly recently.

Yes, volcanoes will emit about 0.15 - 0.25 gigatons of carbon annually in the present day.
Why aren't there diamond mountains on earth?
Diamonds form at such depths and pressures that they only reach the surface through explosive kimberlite volcanic eruptions which could spread them over a fairly wide region. Kimberlite volcanic eruptions are not known for their mountain building capabilities.
How do you use lava to learn about the ages of sedimentary rock?
It is fairly easy to determine the age of lava or volcanic ash using radiometric dating, but much harder with sedimentary rock. But, if a layer of sedimentary rock is in between two layers of volcanic rock, then we know if had to have formed after the first layer and before the second one. If we know how old the volcanic layers are, then we have a general idea of how old the sedimentary layer is as well.
Is there any natural gold deposits in Hawaiian islands?
Hawaii is 100% volcanic material and fairly 'young' geographically speaking. Therefore, sorry to say, there are no known gold deposits in or on the Island State.
