Igneous rocks make up about 90% of the Earth's crust by volume. This includes both intrusive igneous rocks, like granite, which form below the surface, and extrusive igneous rocks, like basalt, which form from lava at the surface. The predominance of igneous rock is due to the processes of magma formation and solidification that occur in the Earth's mantle and crust.

What are the two kinds of crust?
Earths crust is the outer shell of our planet. The Earth has two types of crust. Continental crust contains igneous, sedimentary and metamorphic rocks that covers the continents. Oceanic crust contains igneous basalt rocks derived from the upper mantle that cover the all the ocean floors. The igneous rocks are covered with sediments carried into the oceans from large rivers like the Amazon and Mississippi Rivers.
How much of earth's surface do igneous and metamorphic rock cover?
Igneous and metamorphic rocks collectively cover about 80% of the Earth's surface. Igneous rocks are primarily found in oceanic crust, while metamorphic rocks are prevalent in continental crust, particularly in mountain ranges formed by tectonic activity. The remaining 20% of the Earth's surface is primarily covered by sedimentary rocks, which are found in sedimentary basins and on continental shelves.
Is the Moon's crust thinner or thicker than earth?
The Moon's crust is generally thinner than Earth's crust. The Moon's crust is estimated to be roughly 30 to 40 kilometers thick, while Earth's crust is on average about 40 kilometers thick but can be much thicker in some areas like continental crust.
What are the earths layers in order from thickest to thinnest?
The Earth's layers, from thickest to thinnest, are the inner core, outer core, mantle, and crust. The inner core is solid and primarily composed of iron and nickel, while the outer core is liquid. The mantle is much thicker than the crust and is made of semi-solid rock, and the crust is the thinnest layer, composed of solid rock and minerals.

How much of earths crust is made up of oxygen and silcon?
47 % oxygen & 27% silicon.
How Much Aluminum Is Found In The Earths Crust?
8.1% by weight
What type of rock is formed by magma that cools deep below earths crust?
Igneous rock, specifically intrusive igneous rock, is formed by magma that cools deep below Earth's crust. This slow cooling process allows large crystals to form, resulting in rocks such as granite, diorite, or gabbro.
How much of the earths surface is covered by india?
India is not covering some of the earth's crust but part of the earth's crust is part of India
Which is hotter the sun or the earths crust?
The sun is much hotter than the Earth's crust. The temperature at the Earth's core is estimated to be around 5700 degrees Celsius, whereas the temperature at the surface of the sun is about 5500 degrees Celsius.
Where is oxygen most commonly found in?
under the earths crust in trees and everywhere you can think of pretty much
What type of rock is there most of?
Most of the Earth's crust is made up of igneousrocks but much of igneous rock is under the surface and not seen. Most of the rocks you see, those exposed on the surface, are sedimentary rocks.
How much of earths mass is made by the crust?
u shood no that ur an idiot if u wanna no then lick a toilet LOL i wouldnt be talking cuz u dont know how to spell should!!;)
How much of earths mass made up by the core?
The core is 33% of the Earths mass
How much of the earths atmosphere is made up of nitrogen and oxygen?
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
How wide is the crust?
The Earth's crust can vary in thickness, but on average it is about 5-70 kilometers (3-44 miles) thick. However, it can be much thicker under mountain ranges and thinner under the ocean floor.
