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.


What can you tell about an igneous rock that has a coarse texture?

It is most likely formed underground.


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 is the difference between an igneous rock with a glassy texture and one with a fine texture?

The main difference is that the glassy textured igneous rock cooled from lava with extreme quickness, while the one with a fine texture cooled less quickly. Obsidian is a natural glass, created by rapidly cooling lava, where mineral crystals do not have enough time to form before the lava solidifies.


What is the resulting texture of igneous rock that is formed from extremely rapid cooling lava in which no crystals form?

The resulting texture is called glassy. This texture forms when lava cools so quickly that no crystals have time to grow, resulting in a smooth, glass-like appearance.

What could be determined if you knew the texture of an igneous rock?

You could determine whether the rock cooled underground or above the surface.


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 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 is the texture of igneous rock?

Phaneritic is the texture of igneous rocks. These types of rocks crystallized slowly.


What observation about an igneous rock would support the inference that the rock cooled slowly underground?

The rock would have visible mineral crystals--a phaneritic texture.


Do igneous rocks cool quickly underground?

Igneous rocks can cool quickly underground depending on the surrounding temperature and pressure conditions. For example, magma chambers deep underground can cool slowly over thousands to millions of years, while shallow intrusions may cool more rapidly. The cooling rate affects the resulting mineral composition and texture of the igneous rock.


What texture does and extrusive igneous rock have?

fined grain texture


When igneous rocks solidify what kind of texture do they have?

Crystalline texture.


What size of rock texture refers to igneous rock?

The size of the mineral crystals in an igneous rock determines the rock's texture.
