What are two examples of fined grained igneous rocks?
Basalt and rhyolite are examples of fine-grained igneous rocks.
What type of igneous rocks are there?
There are two main types of igneous rocks: intrusive (plutonic) rocks which form beneath the Earth's surface through slow cooling of magma, and extrusive (volcanic) rocks which form on or above the Earth's surface through rapid cooling of lava. Examples of intrusive igneous rocks include granite and diorite, while examples of extrusive igneous rocks include basalt and rhyolite.
What are two examples of fine-grained igneous rock?
Two examples of fine-grained igneous rocks are basalt and rhyolite. Basalt is a dark-colored rock with a composition rich in iron and magnesium, while rhyolite is light-colored and has a high silica content. Both rocks form from the cooling and solidification of molten magma.
Which two igneous rocks have phaneritic textures?
Even in the most generalized classification, more than two igneous rocks have phaneritic textures. In that generalized classification, they are granite, diorite, gabbro, and peridotite.
What are two types of igneous rocks?
Two types of igneous rocks are intrusive igneous rocks, which form from magma that cools and solidifies beneath the Earth's surface, and extrusive igneous rocks, which form from lava that cools and solidifies on the Earth's surface.
What are examples of two rocks that are high in silica?
Two examples of rocks that are high in silica are granite and rhyolite. Granite is an igneous rock that typically contains around 70-75% silica, while rhyolite, also an igneous rock, can have silica content exceeding 70%. Both rocks are often associated with volcanic activity and can form in continental crust environments.
What are two possible fates for a igneous rock?
Two of the most common fates of igneous rocks are to become sediment (and later sedimentary rocks) or to become metamorphic rocks.
What are two examples of igneous rocks and their uses?
Two examples of igneous rocks are granite and basalt. Granite, known for its durability and aesthetic appeal, is commonly used in countertops, flooring, and monuments. Basalt, being dense and strong, is often utilized in construction, particularly for roads, as well as in the production of stone wool insulation. Both rocks are essential in various architectural and engineering applications.
What is an ingenous rock?
an ingenous rock is type of rock formed when lava or magma cools and hardensIt's igneous rock, not ingenious rock. Igneous rock is lava that has hardened into stone. Two examples are obsidian and pumice.
What type of rock is an igneous rock?
Igneous rocks are usually classified first by their color index. The color index is separated into four categories. Felsic rocks are the lightest and are composed of mostly quartz and potassium feldspar. Intermediate rocks are the second lightest and are made up of mostly plagioclase feldspar, pyroxene, amphibole, and biotite. Mafic rocks are made up of plagioclase feldspar, pyroxene, and amphibole. Ultramafic is made up of mostly olivine, with pyroxene and amphibole.
What kind of rock does magma form when it hardens?
If the magma cools on the surface of the crust, it is called extrusive igneous rock, such as pumice, basalt or rhyolite. If the magma cools inside the crust, it is called intrusive igneous rock, such as granite.
What are the last two igneous rocks?
Terinoman and the Alaxiauspung
