Frage	Antworten
The layers of the Earth can be divided into layers according to its chemical composition as we can see in the picture. These layers are called... Image: Earth Inner Layers Sense Noms (binary/octet-stream)	Crust Mantle Outer core Inner core
The crust is made up of... Image: Crust (binary/octet-stream)	less dense rocks, rich in silicon and aluminium
The mantle is composed of... Image: Mantle (binary/octet-stream)	denser rocks like magnesium
The core is principally made up of... Image: Core (binary/octet-stream)	iron and other metals.
Image: Seismic Discontinuities (binary/octet-stream)	These are the three discontinuity boundaries: Mohorovicic discontinuity Gutenberg discontinuity Lehmann discontinuity
The Mohorovicic discontinuity marks the boundary between	the crust and the mantle
The Gutenberg discontinuity marks the boundary between	the mantle and the outer core
THe Lehman discontinuity marks the boundary between	the outer core and the inner core
