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.

What two types of rock provided evidence of the composition of Earths interior?
Igneous and metamorphic rocks provide evidence of the composition of Earth's interior. Igneous rocks form from the cooling of molten rock (magma), and they can provide information about the chemical composition of the mantle. Metamorphic rocks form from the transformation of existing rocks under high pressure and temperature conditions, offering insights into the conditions present deep within the Earth.
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.
What Evidence Would You Look For If Attempting To Classify A Piece of igneous Rock as Extrusive?
Extrusive igneous rocks have very small crystal grains.
How can you identify an igneous rock?
Intrusive igneous rock is composed of visible mineral crystals, possessing what is referred to as a phaneritic texture. This is evidence that slow cooling of magma occurred deep underground.
What describes rock that was formed when molten rock cooled down?
Igneous rock is formed.
What are the three examples of changes in life that are supported by evidence of rock layers?
sedimentary, igneous, metamrphic -con
Type of rock formed from molten rock?
Igneous rock is formed when magma cools and becomes solid.
Is obsidian metamorphic igneous or sedimentary?
Obsidian is an igneous rock.
