where are egneos rocks found
What else can I help you with?
What grain type is found in extrusive igneous rocks?
Extrusive igneous rocks are usually fine grained.
Is apatite intrusive or extrusive?
Apatite is typically found as an accessory mineral in both intrusive and extrusive igneous rocks. It is more common in intrusive rocks like granite, but can also be found in extrusive rocks like basalt.
Is mica extrusive?
No. A mineral is not inherently extrusive or intrusive. Mica can be found in intrisive igneous rocks and in metamorphic rocks.
Is fluorite an extrusive rock?
No, fluorite is not an extrusive rock. It is a mineral commonly found in hydrothermal veins associated with igneous rocks. Extrusive rocks are formed from lava cooling on the Earth's surface, while fluorite is usually found in veins deep within the Earth's crust.
Is feldspar extrusive or intrusive?
Feldspar can be found in both extrusive and intrusive igneous rocks. In extrusive rocks, feldspar forms when magma cools and solidifies quickly on the Earth's surface. In intrusive rocks, feldspar forms as magma cools and solidifies slowly beneath the Earth's surface.
How are intrusive and extrusive rock different?
Intrusive Rocks are found underneath Earths crust, while Extrusive rocks are found above Earths crust.
Are fossils only found in extrusive igneous rock?
No, in fact plenty of fossils are found in sedementary rocks.
Why it would be easier for geologists to study extrusive igneous rocks than intrusive igneous rocks?
Since extrusive rocks are formed by lava (not magma), the rocks can be found easier because they are on the surface, whereas intrusive rocks are formed underground so they are either harder to get to or they are found in smaller quantities.
How does extrusive differ from intrusive?
Extrusive rocks form from lava cooling on the Earth's surface, leading to rapid cooling and fine-grained texture. Intrusive rocks form from magma cooling beneath the surface, resulting in slower cooling and coarse-grained texture. This difference in cooling rates gives extrusive rocks their characteristic fine-grained appearance and intrusive rocks their coarse-grained appearance.
How extrusive rocks form?
extrusive rocks can form from Basaltic Lava and Andesitic Lava. :)
Does lava produce Extrusive or Intrusive rocks?
extrusive
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.
