Intrusive igneous and metamorphic. Intrusive igneous rocks are those that solidify underground. Metamorphic rocks are those that are deep underground and subjected to intense heat and pressure, but remain a solid.

What are 2 types of organic rocks?
Metamorphic and Igneous are two types.
What are some examples of rocks cooled quickly?
Two examples that come to my mind right away are Basalt and Obsidian. You can tell on your own if a rock has cooled quickly by whether or not you can see individual grains of minerals within the rock. So if you cant see any, then its most likely that the rock cooled quickly.
What are two examples of Metomorphic rocks?
Slate and marble are examples of metamorphic rocks. Other metamorphic rocks include gneiss, schist, and quartzite. All metamorphic rocks are formed from other rock types.
What is the difference between the two types of metamorphic rocks?
how is metamorphic rock different than intrusive rock
What makes sedimentary rocks different from other rocks?
Igneous is basically fresh out of a volcano. There are two types: rocks that got cooled slowly, and those that were cooled really fast. After a while, these rocks will break down into sediment, and will form into layers. Then the sediment will go through cementation, where they stick together. At that point, its sedimentary rock! (Like sandstone, in the Grand Canyon!)
What are the two main properties of igneous rock?
There are lots, but they get sorted into 2 categories, volcanic and plutonic. Volcanic are rocks that cooled on/near the surface (quickly), and plutons are rocks that cooled deep below the surface (slowly).
What is the difference between the two types of igneous rocks?
Extrusive igneous rocks form from magma that erupted onto the surface as lava, where it cooled quickly. On the other hand, intrusive igneous rocks form from magma that cooled slowly, deep underground.Obsidian has tiny crystalsGranite has large crystalsIgneous rocks do not contain any fossils. This is because any fossils in the original rock will have melted when the rock melted to form magma.
Name two types of cooling systems on an engine?
Air cooled & Liquid cooled
Which two igneous rocks are formed by fast cooled lava?
Obsidian and Pāhoehoe lava
What are two types of organic rocks?
sedimentary and metamorphic rocks
What are two types of igneous rocks?
Two types of igneous rocks are intrusive which is found in a volcano. And extrusive which is found outside of a volcano.
Where are the two types of igneous rocks made?
Extrusive igneous rocks , Intrusive igneous rocks
What are 2 types of organic rocks?
Metamorphic and Igneous are two types.
What are the two types of rocks in Stonehenge?
sandstone and healing rocks that they brought from Africa
How were rocks used in the building of some types of castle?
Two layers of rocks (gaps in rocks filled with mortar) and earth in between the two layers of rocks.
Can a sedimentary rock be directly transformed into a igneous rock?
Yes, by heat and pressure. It could turn into two types of igneous rocks: intrusive and extrusive. An intrusive igneous rock is formed by heat from a volcano. It is cooled slowly, and has big crystals. An extrusive igneous rock is formed outside a volcano. It cools slowly and has small/ not visible crystals. So basically, if the sedimentary rock gets into a volcano, it can turn into an igneous rock. Hope that answered your question.
What are different types of sedimentary rock?
Coal and Sandstone are two types of sedimentary rocks.
