What are the characteristics of igneous rocks formed underground?

Usually they have larger crystals and coarser grain than those formed above ground.


Do rocks with small crytals form underground or above ground?

Rocks with small crystals typically form underground, in environments where the cooling process is slow, allowing crystals to grow and develop. Rocks formed above ground, such as volcanic rocks, tend to have larger crystals due to the rapid cooling process.


Tree nuts are different than peanuts?

Almond, walnut, hazelnut, etc, grow above ground on trees. Peanuts grow underground.


Why would you expect the crystals in an intrusive rock to be larger than the crystals in the extrusive rock?

Because as an intrusive rock cools underground, it will normally cool more slowly than an extrusive (surface) rock. The slow cooling allows more time for the crystals to grow.


How can you tell that gabbro crystalized deeper underground than basalt did?

Gabbro has larger crystals, meaning it had much more time to solidify from magma underground. Larger crystals in igneous rock are an indication of longer cooling times, which result in larger crystal growth.


Why would granite have larger crystals than igneous rocks formed from lava cooled above the earth's surface?

Because crystals in granite had more time to form


Why would granite rock have larger crystals than igneous rocks formed from lava cooled above the earth's surface?

Because crystals in granite had more time to form


How are crystals formed and how does the rate effect the crystal?

Crystals form when particles in a solution come together in a repeating pattern. The rate of crystal formation can affect the size and quality of the crystals, with slower rates often leading to larger, more well-defined crystals. Faster rates may result in smaller crystals with less defined shapes.


Why would granite have larger crystals than rocks formed from lava cooled above earth surface?

Because crystals in granite had more time to form as the magma cooled slowly. Crystals that form on the surface are smaller because they cooled really quickly.


When a igneous rock with large cystals cools what is it?

An intrusive igneous rock has larger crystals than an extrusive igneous rock because it has had a longer period of time to solidify underground.


Do igneous rocks have smaller crystals than those formed above the surface?

Igneous rocks formed within the earth crust have larger crystals than those formed on the surface because they have little or no interaction with atmospheric conditions and they cool very slowly.


Do salt crystals take longer to form than sugar crystals?
