Both Basalt And Granite Are Examples Igneous Rocks

Extrusive rocks are formed on the surface of the earth from lava which is magma that has emerged from underground.

Both basalt and granite are examples igneous rocks.

All rocks of igneous origin consist of magma or molten earth that finds its way up to. Examples of igneous rocks. Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite. The most common rock type in earth s crust is igneous.

Intrusive rocks are formed. For example two rocks from identical magma can become either rhyolite or granite depending on whether they cool quickly or slowly. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. These rocks include andesite basalt dacite obsidian pumice rhyolite scoria and tuff.

Basalt and granite are similar in the they are both igneous silicate rocks and common on earth. Volcanic rocks are also called extrusive igneous rocks as opposed to intrusive igneous rocks. In geology a pluton is a body of intrusive igneous rock also called plutonic rock that is crystallized from magma slowly cooling below the surface of the earth although pluton is a general term to describe an intrusive igneous body there has been some confusion around the world as to the definition of a pluton. Some cool so quickly that they form an amorphous glass.

They also have numerous differences. According to bowen s reaction series which mineral crystallizes at the lowest temperature. It forms from subterranean magma chambers that cool and harden beneath the surface and then become exhumed and exposed at the surface. On this basis we are going to look at the commonly identified types of igneous rocks both.

Both are igneous rocks which means that they cooled from a magma the earth gets very hot just below the surface and there is lots of liquid rock. Granite is an igneous plutonic rock which is very common in continental crust. The classical example here is basal t which can have many small crystals or very few large ones. The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents.

Basalt and granite actually have quite a bit in common. Examples of such kind of rocks include pumice basalt or obsidian. The two main categories of igneous rocks are extrusive and intrusive. There are more than 700 known types of igneous rocks and most of them are formed under the earth s crust since volcanic events are not all that frequent.

For example granite and basalt are both igneous rocks with different chemical composition and structure and therefore different weathering rates. Igneous sedimentary and metamorphic rocks have undergone little change since earth formed false. Pluton has been used to describe any non tabular intrusive body and batholith. Excluding the rocks between my ears i d have to say that basalt and granite have the honor of being the most important rocks in the crust.
