What provides the best evidence of the environment in which an igneous rock was formed?
The mineral composition and texture of an igneous rock provide the best evidence of the environment in which it was formed. The type of minerals present, their sizes, and how they are arranged can give clues about the temperature and pressure conditions during its formation. Additionally, the presence of specific features like vesicles, crystals, or layering can also indicate the rock's formation environment.

Which characteristic provides the best evidence about the environment in which a rock was formed?
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.
What characteristic provides the best evidence that obsidian rock formed in an extructive environment?
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.

Which provides the best evidence of the environment in which an igneous rock was formed?
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.
Which characteristic provides the best evidence that obsidian rock formed in an extrusive environment?
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.

Where can igneous rocks find?
Igneous rocks are rocks formed by magma. so the best place to find igneous rocks would be by volcanoes or where a volcano once erupted.
Where in your home can you find an igneous rock?

How would you best describe the texture of an igneous rock that formed extremely slowly underground?
The texture of an igneous rock that formed extremely slowly underground would likely be coarse-grained. This slow cooling process allows for the growth of large mineral crystals within the rock, leading to a visibly grainy texture.
The absolute age of a rock is the approximate number of years ago that the rock formed. The absolute age of an igneous rock can best be determined by?
It is best determined by radiometric dating techniques which measure the decay of radioactive elements.
