- A team of researchers from USA and China has discovered a new layer with massive mountains in the earth’s mantle. The layer lacks a formal name and is being addressed as the “660 kilometers boundary”. The recent discovery is expected to give new insights on the formation and evolution of Earth.
- The researchers had used data from Bolivia Earthquake, 1994 – the second largest earthquake ever recorded (8.2 on Richter scale).
- Using the data, the researchers have discovered mountains, as well as other topography on a layer located 660 kilometers downwards that separates the upper and lower mantle.
- The earth is generally classified into three layers: a) crust- The outermost layer of the earth, b) mantle which lies between the crust and the core and is divided into upper and lower mantle and c) core- the deepest zone of the earth which is again divided into the outer and inner core.
