What is much of earths crust made up of?
Water 75%
How much zirconium is in the earths crust?
The concentration of zirconium in the earth crust is between 150 mg/kg and 250 mg/kg.
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.
What feature of the mantle allows movement of the earths crust occur?
The much of the mantle is solid but ductile. This allows it to convect, which aids in plate movement.
What is the crust of the Earth?
The crust is the outermost chemical layer of the Earth, of hard and brittle rock, composed of oceanic crust and continental crust. The crust is typically about 23 miles thick beneath continents, and about 6.5 miles thick beneath oceans. The crust is relatively light and brittle compared to other Earth layers. Most earthquakes occur within the crust. The crust is composed of igneous, metamorphic, and igneous rock, but primarily igneous rock. The crust is chemically divided into two types. Continental crust is the less dense of the two, granitic in composition, and the thicker of the two. Oceanic crust is more dense, basaltic in composition, and relatively thin. Oceanic crust is being recycled in roughly 200 million year intervals as new crust is being created at mid-ocean ridges and destroyed by the processes of subduction at underwater trenches. The more buoyant continental crust is on average much older, the oldest continental rocks being over 4 billion years in age. Both the oceanic and continental crust are floating on top of the asthenosphere, the physical layer of the upper mantle in which convection currents of heat push and pull the individual segments of crust (known as plates) around. The crust is the thinnest of Earth's layers, comprising a tiny fraction of the planet's total mass.
What is much of earths crust made up of?
Water 75%
How much of earths crust is made up of oxygen and silcon?
47 % oxygen & 27% silicon.
Which is hotter the sun or the earths crust?
The Suns surface is about 6,000K much hotter than the Earths crust. The hottest lava can get at the surface is about 1,400K
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 rocks are formed from cooled magma of lava, sedimentary rocks by sediment under pressure, and mettamorphic from any rock that undergoes much heat and/or pressure.
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
How much zirconium is in the earths crust?
The concentration of zirconium in the earth crust is between 150 mg/kg and 250 mg/kg.
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
