Why does pumice have a lower density than other igneous rocks?
It is a glassy igneous rock, so there are holes in it. The holes make the rock less dense than other igneous rocks that are Not glassy.
How can igneous rock change?
An igneous rock, just like any other rock, can be changed through metamorphic, igneous, and/or sedimentary processes. When exposed to high temp. and pressure, igneous becomes metamorphic. When re-melted, it becomes igneous again. When weathered/eroded, it becomes sedimentary.
What is an example of an igneous rock besides granite and pumice and obsidian?
The word "igneous" comes from the Greek word for fire. Two other igneous rocks are Basalt dark grey to black, and Gabbro dark grey to black.
How do you classify igneous rocks from other types of rock?
Igneous rocks are identified by first looking at the color index. Felsic igneous rocks contain mostly potassium feldspar. Intermediate igneous rocks contain mostly plagioclase feldspar. Mafic igneous rocks contain pyroxene, olivine, and plagioclase feldspar. Ultra mafic igneous rocks contain mostly olivine. Then igneous rocks are identified based on texture. For example, the texture of igneous rocks can be aphanitic, pegmatitic, phaneritic, glassy, vesicular, etc.
What type of rock is?
There are three major types of rocks: igneous, metamorphic, and sedimentary. Rocks are classified based on the process by which they were formed. Sedimentary rocks form from sand, dust, and tiny rock particles that are fused by water and extreme pressure over time. Igneous rocks form from cooled magma or lava; depending on how fast they were cooled and solidified, igneous rocks may or may not go through crystallization. Metamorphic rocks are rocks that changed from either sedimentary rocks, igneous ones, or other metamorphic rocks. These generally form from wind, water, or chemical erosion.
Why igneous rock is the mother rocks?
Igneous rock can be regarded to as the mother rock becausec particles of this rock broken down during the process of weathering and deposited given rise to d formation of sedimentary and metamorphic rock
What are the distinguishing characteristics of homosexuality?
The distinguishing characteristic of homosexuality is a sexual attraction for individuals of the same gender. There is no other characteristic.
What is the difference between intrusive and igneous rocks?
The difference between an Extrusive and Intrusive igneous rock is the way in which they cool. An Extrusive igneous rock cools very fast on the surface and is created by lava. Since the cooling process is very fast extrusive igneous rocks have very small crystals (fine grained). On the other hand an Intrusive igneous rock cools very slowly beneath the surface and is created by magma. Since the cooling process is very slow intrusive igneous rocks have very large crystals (coarse grained). In some instances there is also a third type of igneous rock. Technically it is an extrusive rock, but it resembles glass. This glass type of igneous rock forms when magma/lava is instantly cooled.
Why does pumice have a lower density than other igneous rocks?
It is a glassy igneous rock, so there are holes in it. The holes make the rock less dense than other igneous rocks that are Not glassy.
What kind of rocks make up most of the igneous group?
Basalt and other dark colored igneous rocks are the most with % of 66% and granite and other light to medium colored igneous rocks fill the other half with 44%
What characteristic distinguishing Neptune from other planets?
Neptune is extremely windy.
Can igneous rock be identified by other minerals?
no

What kind of igneous rock texture results from slow cooling magma?
A coarse grained texture, referred to as a phaneritic texture, will be the resultant igneous rock texture. The slower the magma cools the more time minerals have to crystallize and thus grow bigger.
What is fractional crystallication?
thats easy , there is two definition one in chemistry way and the other in geology. chemistry:a process to separate different solutes from a solution geology: a natural process occurring in igneous rocks during which precipitation of minerals takes place
What are other names for igneous rock?
Volcanic rocks
