Examples of igneous rock?
Granite basalt pumice aplite scoria
When igneous rocks from a volcanic eruption cools what does it form?
When igneous rocks from a volcanic eruption cool, they can form either intrusive or extrusive rocks. Intrusive igneous rocks form when magma cools slowly beneath the Earth's surface, resulting in larger mineral grains. Examples include granite and diorite. Extrusive igneous rocks form when lava cools quickly on the Earth's surface, resulting in smaller mineral grains. Examples include basalt and pumice.
What is the difference between basalt and granite?
Granite is lighter in color than basalt. The color of the rocks is dependent on the mineral composition of the rock. Basalt is basic and contains a substantial amount of olivine whereas granite is acidic and is rich in quartz.Basalt is an extrusive igneous rock with small mineral crystals, formed when magma cools and solidifies rapidly; this is usually on the surface of Earth's crust, especially at incidents of seafloor spreading on the ocean floor as contact with seawater cools the magma rapidly.Granite is the foundation of the continental crust. Basalt is the foundation of oceanic crust.Granite is an intrusive igneous rock made from visible mineral crystals, a result of cooling over a longer period of time under the surface of the Earth.Another difference between basalt and granite include their joints. Basalt splits along columnar planes while granite splits along horizontal planes. This difference is due to the difference in their cooling process.granite is a sedimentary rock and basalt is a metamorphic rock
What are the best granite tools?
Granite is an extremely hard substance and tools need to be sharp and precise. Good granite tools include diamond blades for clean cutting; they can be fitted into tile or radial saws as required. Other good tools are snippers, sanding tools and scorers.
What are rocks that form when lava hardens?
Igneous, examples include Granite and Basalt
Examples of igneous rock?

What are two types igneous rocks?
Granite and basalt are the most common types of igneous rock. Igneous rock types, or classifications, also include those that are intrusive and extrusive. Intrusive igneous rock is formed from the solidification of slow cooling magma below the surface. Extrusive igneous rock is formed for the solidification of rapidly cooling lava at or near the surface.
How are intrusive and extrusive classified?
Intrusive or extrusive describe properties of an igneous rock. An intrusive rock is formed within the crust and it insulated and cooled slowly. Some examples of an intrusive rock include diorite, granite, gabbro, and periodite. They have large grains because they have more time for growth. On the other hand, extrusive rocks cool at the surface rapidly. They are comprised of tiny crystals and/or glass. Some examples include rhyolite, andesite, and basalt.
Which are igneous rocks?
== == Igneous rocks have formed from molten material either above (extrusive) or below (intrusive) ground level. Extrusive igneous rocks include obsidian, basalt, and rhyolite; intrusive igneous rocks include gabbro and granite.
What is category of igneous extrusive rock?
Some igneous extrusive rocks include obsidian, basalt, andesite, rhyolite, scoria, pumice, basaltic glass. If you want more, go to page 6 on the Earth Science Reference Tables at the related link.
What are the special care requirements for a granite counter top?
Some of the special care requirements for a granite counter top include applying granite sealer.
What type of extrusive rock would form at a volcano?
Extrusive rock of an igneous origin, formed from the cooling and solidification of lava. Typical examples include basalt, andesite and rhyolite.
What are some igneous rocks other than granite basalt pumice rhyolite and obsidian?
Other intrusive igneous rocks include gabbro, diorite, syenite, monzonite, granodiorite, monzodiorite, anorthosite, troctolite, peridotite, and pyroxeneite. Extrusive igneous rocks include dacite, andesite, phonolite, and trachyte when classified by composition, and tuff, and scoria in terms of texture.
When igneous rocks from a volcanic eruption cools what does it form?
When igneous rocks from a volcanic eruption cool, they can form either intrusive or extrusive rocks. Intrusive igneous rocks form when magma cools slowly beneath the Earth's surface, resulting in larger mineral grains. Examples include granite and diorite. Extrusive igneous rocks form when lava cools quickly on the Earth's surface, resulting in smaller mineral grains. Examples include basalt and pumice.
What does granite contains?
Granite contains several types of minerals. They include quartz, calcite, micas, and tourmaline. Granite can also have trolite and silicate minerals.

Is granite rock a compound?
Granite rock is not a compound but a mixture. It contains a number of elements which include quartz, Phelps and so much more.
