Obsidian is an igneous rock, so it forms from the tectonic activity of an eruption of a volcano. It is a special igneous rock because it is a glass. It forms from an explosive eruption (due to high viscosity and gas content of the magma, which usually is a rhyolitic or andesitic magma). The formation of obsidian is due to the phenomenon of the lava cooling very rapidly that the atoms have no time to arrange themselves in a crystalline structure. So the product is glass.

What often leads to the creation of metamorphic rock?
Heat and pressure are responsible for the formation of metamorphic rock.
What characteristic of a supercell would contribute to tornado formation?
The rotation in a supercell is what leads to tornado formation.
What type of plate boundary leads to subduction?
Convergent plate boundaries lead to subduction. Subduction occurs when one tectonic plate rides over the edge of another tectonic plate which sinks into the mantle as they converge.
Why is sodium not found uncombined?
Its chemical activity is so high that it readily combines with oxygen, forming the oxide. This in turn is highly active, so the presence of water leads to formation of the hydroxide. Even its hydroxide is extremely active, so the common compounds are more complex, such as carbonates.
What is the difference between a divergent boundary on land and a divergent boundary on sea?
The main difference is the type of crust being pulled apart. At a divergent boundary on land, two tectonic plates consisting of continental crust are moving away from each other. This process can result in the formation of rift valleys or a new ocean basin. On the other hand, a divergent boundary in the sea occurs when two tectonic plates consisting of oceanic crust separate. This leads to the formation of mid-ocean ridges and new seafloor.
What often leads to the creation of metamorphic rock?
Heat and pressure are responsible for the formation of metamorphic rock.
What is shaping the surface of the earth?
The surface of the Earth is primarily shaped by two main processes: tectonic activity and erosion. Tectonic activity, such as the movement of tectonic plates and the resulting earthquakes and volcanic eruptions, leads to the formation of mountains, valleys, and other landforms. Erosion, on the other hand, is the process of weathering and transport of material by wind, water, and glaciers, which gradually wears down and reshapes the land surface over long periods of time.
What is Shadow Formation?
That light cannot pass through some materials, and that this leads to the formation of shadows.
What characteristic of a supercell would contribute to tornado formation?
The rotation in a supercell is what leads to tornado formation.
Which phenomenon leads to the formation of metamorphic rocks?
Heat and pressure lead to the formation of metamorphic rocks.
What change leads to the formation of a new substance?
Chemical.
Does Endochondral ossification leads to the formation of cranial bones?
no
What is extrastelar secondary growth?
Extra stelar secondary growth occurs due to th activity of cork cambium.... It produces cork cells and parenchyma cells.... In extra stelar secondary growth there is no annual ring formation.... It later on leads to the formation of periderm and lentices.... sanjana arun
What process leads to formation of thick salt deposits?
Evaperation.
What activity leads to acid precipitation?
Burning coal.
What leads to the formation of clouds?
evaporation from the ocean is carried up to the clouds.
What is leads to the creation of island arcs?
They are the result of the subduction processes related to plate tectonic movements, specifically they mostly form where one oceanic tectonic plate subducts another one.
