Volcanic activity creates what kind of rocks?
Volcanic activity produces extrusive igneous rock.
How do subduction zones lead to the formation of volcanic activity?
Subduction zones lead to the formation of volcanic activity because the water combined with crust and mantle material lowers the rock's melting point temperature, causing the rock to melt and produce magma, which then creates volcanic activity.
What type of rock is formed your volcanic activity?
igneous rocks
Rock that forms as a result of volcanic activity at or near the surface of the earth?
Igneous rock.
Why does the moon have little water?
Because there is no active volcanic activity on the moon. For a planet or moon to develop water, it needs to have active volcanic activity. The steam from erupting volcanoes creates an atmosphere and condensation which, over millions of years, creates oceans. We know the moon had active volcanic activity millions of years ago, because there are pockets of ice on the moon. However, volcanic activity on the moon is now non-existent, therefore, no more water can be produced from volcanic steam.
What is a rock consisting of angular fragments embedded in finer matrix formed by volcanic activity?
Volcanic breccia.
What creates diamonds?
scientests are not sure yet but they are working on the case. volcanic activity for the most part
What type of rock does volcanic activity produce?
Extrusive igneous rock is produced by the solidification of lava.
Can stratification occur in a volcanic rock?
Yes. Volcanic rock laid down by different eruptions, or different phases up eruptive activity will be stratified.
How does volcanic activity affect the formation of volcanic rock?
It depends where the rock was formed. If it was formed inside the earth, it would be rough. If it was formed on the surface, it would be smoother than the rock formed inside the earth.
What was volcanic activity like in the Pennsylvanian time period?
During the Pennsylvanian time period, there was a lot of volcanic activity and these constituted a lot of rock formation. Volcanic ashes also settled on the earth's surface and buried some trees.
What cause rock to be igneous rock?
It starts with molten material [magma], when volcanic activity starts the molten material turns into igneous rock.
