What are rocks that have a glassy texture called?
Obsidian
What is the most common type of rock on earth's surface?
Sedimentary Rocks. 75% of rocks exposed to the surface are sedimentary.
What are the 3 kinds of rocks?
Sedimentary, Igneous and Metamorphic.
What are igneous extrusions?
== == Extrusive igneous rocks are formed from the solidification of lava on or above the surface. Rapid cooling from exposure to air or water results in rapid crystallization of their component minerals, normally creating a fine grained texture as opposed to intrusive igneous rocks which have a coarser texture. Examples of extrusive igneous rocks would include obsidian, pumice, basalt, and rhyolite.
How are igneous rocks that have high levels of quartz classified?
A rock is considered igneous if it formed directly from the cooling of molten rock.
Where can igneous rocks find?
Igneous rocks are rocks formed by magma. so the best place to find igneous rocks would be by volcanoes or where a volcano once erupted.
What would be near igneous rock?
Near igneous rocks, you might find other igneous rocks, metamorphic rocks, or sediments that were derived from the erosion and weathering of igneous rocks. Additionally, hot springs, geysers, and volcanic activity may be present in areas with igneous rocks.
When molten rocks cools what rocks form?

Igneous rocks are formed by the solidification of molten materials.
Are there pictures of igneous rocks?
There are lots of pictures of rocks. In order to find pictures you type "pictures of igneous rocks" into your search engine and click on the "images" tab to see them.
Are igneous rocks made up of igneous rocks?
Sedimentary rock can be made up partially of igneous clasts, but igneous rock is igneous rock.
Where would you expect to find an igneous rock with small crystals?
You would expect to find an igneous rock with small crystals near the Earth's surface where the rock cools relatively quickly, such as in volcanic eruptions or magma intrusions that do not have much time to grow large crystals. These rocks are known as volcanic or extrusive igneous rocks.
Why are igneous are called primary rocks?
Igneous rocks
