The Earth's outermost layer of hard brittle rock is called the 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 the upper layer of the earth. It is where the movementof plates occur due to which earthquakes occur. The Earth's crustis a thin layer of rock, like skin on an apple.
The temperature of the continental crust varies widely across different areas and at different depths.
The approximate radius of the Earth's center to it's surface isabout 6,371 kilometers, which is about 3.959 miles.
The continental crust, (where all the land is) is generally around 30 km (20 mi) to 50 km (30 mi) thick. The oceanic crust (the bottom of the sea) is roughly 5 km (3 mi) to 10 km (6 mi) thick.
The inner core of the Earth is solid iron with a few trace elements. The crust is composed of sedimentary, metamorphic, and igneous rock.
The continental crust and the oceanic crust. Continental crust: When you look at the globe, you see that the surface of the earth consists of a lot of water (71%). The other 29% consists of land. You can divide this land into six big pieces, which are called continents. The different continents …- arranged in decreasing order of size - are: Eurasia (Europe and Asia together), Africa, North-America, South-America, Antarctica and Australia. In the past the division of the continents was different (see plate tectonic). The earth's crust is the thickest below the continents, with an average of about 20 to 25 miles (30 to 40 km) and with a maximum of 45 miles (70 km). The continental crust is older than the oceanic crust, some rocks are 3.8 billion years old. The continental crust mainly consists of igneous rocks and is divided into two layers. The upper part mainly consists of granite rocks, while the lower part consists of basalt and diorite. Granite is lightly-colored, coarse-grain, magma. Diorite has the same composition, but it's scarcer than granite and is probably formed by impurities in the granite-magma. The average density of the continental crust is 2.7g/cmÂ³. Oceanic crust: As the name already suggests, this crust is below the oceans. There, the crust is 4-7 miles (6-11 km) thick. The rocks of the oceanic crust are very young compared with the rocks of the continental crust. The rocks of the oceanic crust are not older than 200 million years. The material of which the oceanic crust consists is for the greater part tholeiitic basalt (this is basalt without olivine). Basalt has a dark, fine and gritty volcanic structure. It is formed out of very liquid lava, which cools off quickly. The grains are so small that they are only visible under a microscope. The average density of the oceanic crust is 3g/cmÂ³. source: http://library.thinkquest.org/C003124/en/crust.htm (MORE)

The answer is 90%. The ten most common minerals make up 90% of the earths crust.
The percentage of carbon dioxide is in the earth's crust is only0.005%. Oxygen on the other hand makes up for 47% of the crust ofthe earth.

Mendelevium is an artificial element, toxic and radioactive, difficult to obtain - only some atoms per experiment.
Polonium is an extremely rare chemical element, accompanying uranium ores; approx. 100 micrograms of polonium in one to (t) of uranium ore.
Metamorphic rocks are created from intense heat and pressure being applied to an existing rock. The existing rock is called the protolith. They can also be formed from lava being poured over the top of the earth's surface, where rocks lay underneath. Metamorphic rocks make up a large part of our ear…ths crust. It is around 40-60% of the earts crust. (MORE)
B/c of the principle of isotasy, the earth's crust is thinnest at the deepest point on the Earth's surface (aka. Death Valley)
In terms of weight, iron makes up approximately 5% of the earthscrust, the fourth most abundant element in the crust. However, remember Earth's Core is nearly all Iron.
The crust is broken up into plates and these plates move on top of the mantle.
The mid-ocean ridges, where crust is being created, is most likely the thinnest and weakest place.
High strength tremors shatter fault lines, creating a large eartquake to split the crust of the earth.
There are many elements in the earth's crust for example: . Oxygen--47% . Silicon--28% . Aluminum--8% . Iron--5% . Calcium--4% . Sodium--3% . Potassium--3% . Magnesium--2% . Titanium--0.5% There are more as well but these are just a few!!
As gold isn't a compound (it's an element), it's not formed in the earth's crust. Because of this, there is a pre-existing, set amount of gold on earth.
The different pieces that the Earth's crust is broken into are known as tectonic plates.
The earth's crust is called the crust because it the outer surface of the earth like the crust of pizza.
A tectonic plate could be described as a huge block of Earth's crust. For more information, please see the related link.
yes, mountains are the result of drifting of earths crust towards each other over millions of result... The Himalaya, Andes etc. mountains were made through this drifting process....
According to 118 118, metamorphic rocks make up about 85% of the earth's Continental crust. According to wiki.answers, 75-80% of the earth's surface is composed of sedimentary rock. 20-25% left to be composed of igneous and metamorphic rock.

Estimates of gold's abundance in Earth's crust range from .001 to .004 parts per million. Rare.
Yes it is. It's called an Alkaline Earth metal because they can be found in the Earth's crust (The word Alkali means Base). When they are found in the Earth's crust, they aren't in an element form but they are widely spread in rock structures.
actually the earths crust is probably thicker at the equator, due to its ovular (not spherical) shape and cintrifical force
There are certain zones in the crust called subduction zones. A plate goes underneath another, and as it goes deeper it melts. This recycles the rock.
Nitrogen is the most abundant gas on the earth crust. Argon is the second abundant gas on the earth crust. Oxygen is the third abundant gas on the earth crust. There are only three but it;s somthing! Hope this information helped you. :) There are not only three types of gasses found on earth but …11 to be exact and scientist are still trying to discover some more. The gasses found on Earth include Carbon, Nitrogen, Oxygen, Fluorine, Neon, Helium, Chlorine, Argon, Krypton, Xenon, Radon, and Hydrogen. (MORE)

Compression is a stress state that acts to decrease the size / volume of an object. As such any force resulting in pressure or stress that acts to "squash" the crust is compression. This commonly occurs at convergent plate boundaries were one tectonic plate is colliding with another.
Argon is a gas and is found in the earth's atmosphere; not in the earth's crust.
The Earth's crust is approximately 1.65 % of the total volume of Earth.

I cannot give you an exact figure but my guess is that it is > 90 %. It strongly depends on the minerals present and on the coordination of the elements within these minerals, how large the ionic volumina are. Furthermore pressure and temperature are of importance. Oxygen is present as an anion i…n almost all minerals in the crust (volumetrically speaking) and has a much larger ionic volume (~0.0082 nmÂ³) than the other very abundant elements (all of them are cations). E.g. usual ionic volumina of silicon are 0.00026 to 0.00052 nmÂ³ and ionic volumina of aluminium are typically 0.00052 to 0.0014 nmÂ³. Because in all common silikates minerals > 50 % of the ions are oxygen, its volume fraction on the Earth's crust is very large. (MORE)
