Mineral composition is a key characteristic that provides evidence about the environment in which a rock was formed. Different minerals form under specific temperature, pressure, and chemical conditions, offering valuable clues about the geological processes that shaped the rock.
the date for which the rock formed
The characteristic that provides the best evidence that obsidian rock formed in an extrusive environment is its glassy texture. This texture indicates rapid cooling of molten lava, preventing the formation of large crystals. Additionally, the presence of gas bubbles or vesicles can further suggest that the lava cooled quickly upon exposure to the surface environment.

The texture and mineral composition of the igneous rock provide key evidence of the environment in which it was formed. Additionally, the presence of features such as vesicles (gas bubbles), crystal size, and orientation can also offer clues about the conditions of formation. Chemical analysis and the rock's relationship to surrounding geological features can also provide valuable information.

the date for which the rock formed
The glassy texture of obsidian is the best evidence that it formed in an extrusive environment. Obsidian is rapidly cooled lava with no time for crystal growth, resulting in a smooth, glass-like texture.

Igneous rock is formed when magma cools and becomes solid.
An igneous rock formed from magma is intrusive.
Igneous rock is formed.
Igneous rocks are formed when lava cools. After a eruption, the lava cools, and the igneous rock is formed.
