The temperature of the crust increases gourmet catering with profundiad reaching values up to 200

The crust is relatively thin and has probably been recycled and destroyed by strong tectonic gourmet catering movements and significant impacts of asteroids that were common in the early ages of the solar system.
It is located in the upper part of the lithosphere with a thickness between 3 to 100 miles. The average gourmet catering density used in the upper crust is between 2.69 tonnes / m3 and 2.74 tons / m 3 and in the lower crust between 3 and 3.2 tons / m3.
The age of the oldest oceanic crust in the sea is 200 million years old while the oldest continental rocks have a range between 3.7 and 4.3 billion years found in Austraia gourmet catering and Canada formed in the Archaic period, so that estimated that the average age of the continental crust is about 2 billion years.
The Earth's crust or "lithosphere" consists of a variety of igneous, metamorphic and sedimentary rocks as basalts and granites although on average can be said to be composed of a similar to andesite (volcanic rock igneous extrusive with about 60 items % of silicon dioxide SiO2 and accessory minerals) and is enriched with incompatible elements in basaltic or volcanic ocean compared to the mantle.
As elements, the crust is made of oxygen-O (45%), silicon-Si (27%) aluminum-Al (8%), iron Fe (6%), calcium-Ca (5%) , sodium-Na (3%), potassium-K (2%), magnesium (3%), titanium (1%) totaling 98.9% of the cortex and more scarce elements.
Regarding compounds estimated bark surface has a composition with 61% silicon oxide (SiO2), 16% aluminum oxide (Al2O2), 7% iron oxide (FeO), 6% calcia (CaO), 5% magnesium oxide (MgO), 3% sodium oxide (Na2O), 2% potassium oxide (K2O) and 1% titanium oxide (TiO2)
The temperature of the crust increases gourmet catering with profundiad reaching values up to 200 C and 400 C at the edge of the upper mantle. The temperature rose to 30 C for each kilometer of depth in the top of the crust.
