10 Facts about Earth’s Layers
The following post below narrates Facts about Earth’s Layers. Edmond Halley proposed the idea that earth contained a hollow shell in 1692. He printed the idea on Philosophical Transactions of Royal Society of London. The innermost core of earth was covered by two inner concentric shells. Halley stated that the thickness of the hollow shell was around 500 miles. The earth has the density of 5,515 kilogram per meter cubic. Let us find out other interesting facts about layers of earth below:
Facts about Earth’s Layers 1: the core of earth
There are two parts found on the core of earth. The liquid outer core extends at the radius of ≈3,400 kilometer. The radius for the solid inner core is measured at ≈1,220 kilometer.
Facts about Earth’s Layers 2: Inge Lehmann
Inge Lehmann is an important person when talking about geology of earth. Lehmann discovered that earth had inner core in 1936.
Facts about Earth’s Layers 3: the composition of earth’s core
Iron and nickel are considered as the two major components found on earth’s core. It is believed that 80 percent of earth’s core is made of iron. It also features the dense and light elements. Get facts about earth’s interior here.
Facts about Earth’s Layers 4: speculation about innermost part of earth
The gold and platinum are the two elements speculated by the scientists to find at the innermost parts of earth.
Facts about Earth’s Layers 5: magnetic field
The liquid outer core of earth produces the magnetic field. The solid inner core helps to stabilize the magnetic field.
Facts about Earth’s Layers 6: the silicate rock
The silicate rock is the primary material, which composes earth and other terrestrial planets like Mercury, Mars and Venus. Check facts about earth history here.
Facts about Earth’s Layers 7: the interior of earth
Several layers are found at the interior of earth. Each layer is made of different materials. The location of the earth’s mantle is between the outer core and crust. The thickness of earth’s mantle is measured at 1,793 miles or 2,886 km. Almost 84 percent of earth’s volume is created from mantle.
Facts about Earth’s Layers 8: the upper mantle
The upper mantle is divided in two parts. Both are the lowermost part of lithosphere and inner asthenosphere.
Facts about Earth’s Layers 9: the rigid rock
The rigid rock composes the lowermost part of the lithosphere, which has the thickness of 31 to 75 miles.
Facts about Earth’s Layers 10: the plastic flowing rock
The plastic flowing rock is discovered on the inner asthenosphere.
