What part of the earth is about 1802 miles thick?
The Earth's crust is generally about 1802 miles thick. It consists of both continental crust (thicker, around 22 miles) and oceanic crust (thinner, around 5 miles). Below the crust, the mantle extends for about 1800 miles before reaching the Earth's outer core.
Is the crust of earth the only solid layer?
No. The mantle and inner core are also solid.
How thick is each layer of the Earth?
The crust is 19 miles/33km thickThe upper mantle is 415 miles/667km thickThe lower mantle is 1365 miles/2200km thickThe outer core is 1405 miles/2265km thickThe inner core is 760 miles/1220km thick (diameter of 2440 km)
Is Earths mantle is thinner than earths crust?
The crust is much thinner than the mantle.
What is underneath the crust of the earth?
Underneath the crust of the Earth, there is the mantle, which is a layer of solid rock that extends about 1,800 miles (2,900 kilometers) deep. Below the mantle is the outer core, which consists of liquid iron and nickel. The inner core is at the very center of the Earth and is composed of solid iron and nickel due to the immense pressure and heat.
How many miles thicker are the outer core and the inner core together than the mantle?
The radial thickness of the inner and outer core is equal to 3,486 km (2,166 miles). The mantle is 2,885 km (1,793 miles) thick. As such the inner and outer core combined is 601 km (373 miles) thicker than the mantle.
How far is core from mantle?
3160 miles-mantle to inner core.
How thick is the inner core plus the outer core?
The distance from the boundary between the mantle and the outer core, to the center of the Earth, is around 3,470 km, or 2,156 miles.
The thickest layer of the earth?
The thickest layer of the Earth is its mantle.

Is the crust of earth the only solid layer?
No. The mantle and inner core are also solid.
What layer in earth is 3500 km thick?

What is the tempuerature of the mantel?
The inner mantle averages 5400 degrees F and is anywhere from 200 to 2000 miles deep. The outer mantle averages 2500 to 5400 degrees f and is anywhere from 10 to 200 miles deep. (Both depths measured from sea level)

How long get to the center of the world if you were to dig?
You would die before you got very far. The earth's crust is 124 miles thick. After that you come upon the mantle (which is about 100-250 miles thick), which consists of molten rock (more commonly known as magma) and is split into three layers: Upper mantle, Mantle, Inner Mantle, each ranging between 600-900 degrees Celsius (or 1,112-1,652 degrees Fahrenheit). Once through the Mantle, you come upon the Inner core which is 1,400 miles thick and made up of Iron and Nickel and has a temperature of 6,692 degrees Fahrenheit. Then you have the inner core which is 750 miles thick and made of solid iron and nickel and has a temperature of about 13,000 degrees Fahrenheit (THAT"S HOTTER THAN THE SUN!) So as you can see, you would be dead before you reach the center of the earth.

What is the earth's inner mantle?
The Mantle The layer above the core is the mantle. It begins about 6 miles(10 km) below the oceanic crust and about 19 miles (30 km) below the continental crust (see The Crust). The function of the mantle is to separate the inner mantle and the outer mantle. It is about 1,800 miles(2,900 km) thick and makes up nearly 80 percent of the Earth's total volume. Science deals with the structure of the mantle in two different ways. One way is based on its chemical construction (the material), the other on the way layers stream or move.What does the mantle consist of? Based on the chemical construction: Inner Mantle: the inner mantle can be found between 190 miles (300 km) an 1,800 miles (2,890 km) below the earth's surface. The average temperature is 5400 ºF (3000ºC), nevertheless the rock is solid because of the high pressures. The inner mantle for the biggest part probably consists of sulphides and oxides of silicon and magnesium. The density is between 4.3g/cm³ and 5.4g/cm³. Outer Mantle: The outer mantle is a lot thinner than the inner mantle. It can be found between 7 miles (10 km) and 190 miles (300 km) below the surface of the earth. You can divide the outer mantle into two different layers. The bottom layer is tough liquid rock and probably consists of silicates of iron and magnesium. The temperature in this part is between 2520 ºF (1400ºC) and 5400 º F (3000ºC) and the density is between 3.4g/cm³ and 4.3g/cm³. The upper layer of the outer mantle consists of the same material but is stiffer because of its lower temperature.Based on the way layers stream or move: From this perspective, you look at the outer mantle and the crust together. Here we make a difference in asthenosphere and lithosphere.Asthenosphere: The tough liquid part of the outer mantle.Lithosphere: The stiffer part of the outer mantle and the crust. The lithosphere 'floats' on the asthenosphere, like ice on water.What Influence does the Mantle Have? Because the earth is very hot inside, a current of heat flows from the core to the crust. This is called convection current and it also takes place in the mantle. This current cools down as it comes closer to the surface of the earth. As a result, the rising of the current decreases and goes into horizontal direction along the bottom of the crust. When the current cools down more, the convection current descends again and goes to the inner earth. There the temperature increases and the current rises again. This goes on and on. When the current comes at a weaker part of the crust, for example at a volcano, magma comes above the earth's surface. The convection current along the bottom of the crust causes the moving of the tectonic plates. This is called plate tectonics. The movement of these plates goes very slowly. The bumping of two tectonic plates causes an earthquake.From: http://mediatheek.thinkquest.nl/~ll125/en/mantle.htm
