Obsidian goes through the rock cycle the same way other rocks go through the rock cycle, either through metamorphosis, weathering and erosion and subsequent lithification into sedimentary rock, or by melt into another igneous rock.
As sand, it is a piece of sediment. If it goes through a lot of pressure, it would then become metamorphic. If the metamorphic rock melts into magma, then cools, it would then become igneous. When the igneous rock goes through weathering and gets worn down, it then becomes sediment again.
The rock cycle entails the life span of rocks, beginning from magma generation through its ascent to its evolution. It gives account of all the three basic forms of rocks and how they are interrelated and transformed from one to another. Obsidian is formed in the Igneous phase of the rock cycle. Its formed as a result of rapid cooling of erupted lava, Obsidian also referred to as "Volcanic Glass" is an "Extrusive Igneous Rock" and comes to existence when lava at the earth surface cools at a very fast rate that its crystallization stage hardly comes to play, it appears as a massive rock that is very fine and smooth to touch, and glassy in appearance.
When felsic lava cools rapidly without crystal growth.
Obsidian goes through the rock cycle by being exposed to sediment for too long
The rock cycle is Sedimentry and Igneous rocks can be changed.

Through the processes of weathering and erosion.
Exposure, weathering, and erosion can transform a metamorphic rock into sediments.
It is called weathering. Erosion is the weathering and movement of rocks and rock fragments.

Erosion.
Erosion does not cause weathering. Erosion is a TYPE of weathering in which surface soil and rock are worn away through the action of glaciers, water, and wind.
Well, it is not weathering. It is Erosion. The river swept through the rock and deposoted the bit of rock in another area.
Through the processes of weathering and erosion.
Weathering and erosion
Exposure, weathering, and erosion can transform a metamorphic rock into sediments.
Any and all rock can be changed into sediment by weathering and erosion.
This is called erosion.
The rock or rocks will undergo weathering and erosion.
It is called weathering. Erosion is the weathering and movement of rocks and rock fragments.
By weathering and erosion. The types of weathering used is:physical weathering- when a plant grows inside a rock and the roots break it apart; abrasion- mechanical weathering - erosion- and chemical weathering - acid rain, water weathering and erosion.
