Where is the thickest region of the earth s crust in the world?

On the Tibetan Plateau.

The average global crust thickness is 35 km, while the Tibetan Plateau has a crust thickness of 70 km.

The earth's crust is the most superficial layer of the earth, and there are continental crust and oceanic crust. The continental crust is generally 33-35 km thick, with the thickest areas being about 50-70 km. China's Qinghai-Tibet Plateau is one of the regions with the largest crustal thickness in the world, with an average thickness of 70 kilometers.

The continental crust is usually divided into three layers and is made up of three different types of rocks. At the top are sedimentary rock formations, followed by granite and basalt formations below.

The thickness of the oceanic crust is small, on average only 6-8 km; At the top of the oceanic crust is a thin layer of seafloor sediment, and down there is basalt. Deep-sea drilling and ** studies have also found that there are also wall-like gabbro and diabase beneath the oceanic crust basalt, as well as serpentine formed by alteration of ultramafic rocks.

From the structure of the continental crust and the oceanic crust, it can be seen that the rocks scattered in the earth's crust have a certain regularity in distribution. The most obvious difference in rock composition between the oceanic crust and the continental crust is that no granite layers have been found in the oceanic crust, while granite bodies are distributed in a large area in the continental crust.

You don't need to ask, near the Himalayan plateau (I guess, because that's the highest).

The thickest part of the world's crust is in the Gangdis Mountains (where the Eurasian plate and the Indian Ocean plate are superimposed).

Mount Everest on the Tibetan Plateau.

Mount Everest! Hehe.

The average thickness of the earth's crust is about 17 km.

The earth's crust is the outermost layer of the earth's solid surface structure, with an average thickness of about 17 kilometers, of which the continental crust is larger, with an average thickness of about 39-41 kilometers. The crust is thicker in the mountains and plateaus, up to 70 km; Plains and basins have relatively thin crusts. The oceanic crust is much thinner than the continental crust, only a few kilometers thick.

The Qinghai-Tibet Plateau is the thickest place on Earth, with a thickness of more than 70 kilometers. The crust in the submarine valley of the central Atlantic Ocean near the equator is only 1,000 meters thick; The crust of the abyssal trench in the eastern part of the Mariana Islands in the Pacific Ocean is the thinnest and the thinnest on Earth.

The chemical element with the most elements in the earth's crust is oxygen, which accounts for the total weight; followed by silicon, which accounts for; The following are aluminum, iron, calcium, sodium, potassium, magnesium. The lowest abundances were astatine and francium, accounting for about 1 in 1023. The above 8 elements account for the total weight of the crust, and the remaining 80 elements account for the total.

The percentage of atoms with the average content of various chemical elements in the earth's crust is called the atomic Clark value, and the chemical element with the highest number of atoms in the earth's crust is still oxygen, followed by silicon, and hydrogen is in third place.

The thinnest part of the earth's crust is in the Mariana Trench.

The Mariana Trench is both the thinnest crust and the deepest part of the ocean, 6-11 kilometers deepest, the deepest known ocean, where high water pressure, complete darkness, low temperatures, low oxygen levels, and a lack of food resources make it one of the harshest areas on Earth.

The Mariana Trench, also known as the Mariana Trench. It is located in the northeastern part of the Philippines, in the Mariana Islands.

Near the bottom of the Pacific Ocean, from Iwo Jima in the north.

Southwest to the vicinity of Yap Island. It has the Aleutian, Kuril Island, Ogasawara and other trenches in the north, and the New Britain and New Hebrides trenches in the south, with a total length of 2,550 kilometers, an arc, and an average width of 70 kilometers. It is estimated that the trench has been formed for 60 million years.

1. The earth's crust is a thin layer of crust on the earth's surface.

Its thickness is roughly the radius of the Earth.

of 1,400, but the thickness varies from place to place, with the continental part averaging more than 37 km and the oceanic part only about 7 km thick. Generally speaking, the crust of high mountains and plateaus is the thickest, such as the Qinghai-Tibet Plateau in China.

The Earth's crust can be up to 70 km thick.

2. Mantle. Earth's crust and core.

between the middle layers. The average thickness is:

More than one kilometer. 1914, BGutenberg measured the depth of the interface between the Earth's core and the mantle at 2,900 km, which is quite accurate and is only 15 km short of the newly calculated value. The mantle is further divided into the upper mantle (

350 km deep) and the lower mantle. There is a low-velocity layer of ** waves in the upper mantle, and the low-velocity layer is above the relatively hard top of the upper mantle. The top of the upper mantle and the earth's crust are often referred to as the lithosphere.

The global lithospheric plates make up the outermost structure of the earth, and the tectonic movement of the earth's surface is mainly carried out within the lithosphere.

3. The Earth's core. The core part of the earth is mainly made of iron.

Nickel element. Compose.

The radius is 3480 km.

Year. i.According to the longitudinal wave passing through the earth's core, Lyman proposed that there is a sub-interface in the earth's core, and the earth's core is divided into two parts: the outer core and the inner core. Since the outer nucleus cannot allow transverse waves to pass through, it is inferred that the state of matter of the outer nucleus is liquid.

The thickness of the earth's crust is about 17 kilometers, and the earth's crust refers to the solid shell composed of rocks, the outermost layer of the earth's solid sphere, an important part of the lithosphere.

The chemical composition of the upper layer is mainly oxygen, silicon, and aluminum, and the average chemical composition is similar to that of granite, which is called granite layer, and some people also call it "silicon-aluminum layer". This layer is thin at the bottom of the ocean, especially in the ocean basin floor, and even absent in the central Pacific Ocean, and is an uncontinuous circle.

The lower layer is rich in silicon and magnesium, and the average chemical composition is similar to that of basalt, which is called the basalt layer, so some people call it the "silicon-magnesium layer" (another way of saying that the entire crust is a silicon-aluminum layer, because the aluminum content of the lower layer of the earth's crust still exceeds that of magnesium; The rock part in the upper part of the mantle has a very high magnesium content, so it is called a silicon-magnesium layer); It is distributed in both continents and oceans, and is a continuous circle. The two floors are separated by a Conrad discontinuity.
