What igneous rocks does not have a glassy texture?
Granite, diorite, and gabbro are examples of igneous rocks that do not have a glassy texture. These rocks are formed from slowly cooled magma underground, allowing time for crystals to grow, giving them a coarse-grained appearance.
What is Best evidence of the environment in which an igneous rock was formed?
Texture
Which best describes how igneous rocks are formed?
nothing
What provides the best evidence of the environments in which an igneous rock was formed?
texture
How are metamorphic rocks formed underground?
Metamorphic rocks are formed underground through the process of heat and pressure altering existing rocks. When rocks are buried deep in the Earth's crust, they are subjected to high temperatures and pressures that cause their mineral composition and texture to change. This results in the formation of metamorphic rocks from pre-existing igneous, sedimentary, or other metamorphic rocks.
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.
What can you tell about an igneous rock that has a coarse texture?
It is most likely formed underground.
What igneous rocks does not have a glassy texture?
Granite, diorite, and gabbro are examples of igneous rocks that do not have a glassy texture. These rocks are formed from slowly cooled magma underground, allowing time for crystals to grow, giving them a coarse-grained appearance.
How would you describe the texture of an igneous rock that formed extremely slowly underground?
An igneous rock that formed extremely slowly underground would likely have a fine-grained texture with small mineral crystals. This slow cooling process allows for the minerals to grow larger and more interlocking, resulting in a strong and dense rock with no visible grains or pores.
How igneous rocks formed underground?
Igneous rocks are formed underground from a very hot substance called magma. As magma cools and hardens under extreme pressure, it forms igneous rocks.
What describes rock that was formed when molten rock cooled down?
Igneous rock is formed.
An intrusive igneous rock will have what type of texture?
Intrusive igneous rock has a coarse, visible crystalline texture. Intrusive igneous rocks are formed from slow cooling of magma. The additional time spent in a liquid state allows for the creation of larger mineral crystals. An igneous rock with a coarse texture is said to be phaneritic.

What are rocks that form when magma cools underground?
Intrusive igneous rocks, such as granite and diorite, form when magma cools underground. These rocks have a coarse-grained texture due to the slow cooling process, allowing large mineral crystals to form within the rock. Intrusive rocks are typically found in plutons or batholiths beneath the Earth's surface.
