Facts about The Mantle define the thick layers of solid and hot rocks located between the molten iron core and earth’s crust. The report states that 2/3 of the earth’s mass is from the mantle. The thickness of mantle is around 2900 km. Get more facts about the earth’s mantle below:
Facts about The Mantle 1: the location of the mantle
As I have stated before, the mantle is the layer between the outer core and crust. More than 84 percnet of the earth volume is occupied by the mantle. It is made from a silicate rocky shell with the thickness at 1,800 mi or 2,900 km.
Facts about The Mantle 2: the texture
Most areas of the mantle are in solid form. But it can behave like a fluid in a certain geological time. More than 15 percent of the earth volume is filled with nickel and iron enclosed by the mantle.
Facts about The Mantle 3: the zones
There are two main zones in the upper mantle. The inner asthenosphere comes in 120 mi or 200 km thickness. It is made of plastic flowing rock. The rigid rock with the thickness at 50 till 120 km is located in the lowermost part of lithosphere.
Facts about The Mantle 4: division of mantle
There are some sections which divide the mantle. They are the upper mantle, transition zone and lower mantle. Each has their own thickness. The variable thickness can be seen in the core mantle boundary.
Facts about The Mantle 5: the inner and outer core
The outer core of the mantle is in liquid form, while the inner core comes in solid form. It is due to the fact that each layer has different melting point, pressure and temperature.
Facts about The Mantle 6: the temperature
The temperature of the mantle is around 932 to 1,652 °F or 500 to 900 °C. This temperature is observed at the upper boundary. If the mantle is located at the boundary with the core, it has the temperature more than 7,230 °F or 4,000 °C. Get facts about earth here.
Facts about The Mantle 7: the seabed
When the scientists want to explore the mantle, they prefer to do it at the seabed. It is due to the facts that this seabed has relative thinness.
Facts about The Mantle 8: Project Mohole
Project Mohole was the first attempt that people conducted to explore the mantle. But this project was abandoned in 1966 due to the high cost and repeated failures.
