Hello students, so to answer this question let us write the compositional layers and here the mechanical layers of earth.
00:11
So in the compositional layers the earth has different compositional or mechanical layers.
00:16
The compositional layers, these are determined by their components while mechanical layers are determined by physical properties.
00:36
So first let us write compositional layers.
00:39
The very first layer is called as the crust.
00:42
So it is the outermost layer of earth.
00:47
Then it is solid in nature.
00:50
And it is a solid layer of a rocky planet or natural satellite.
00:55
And it is chemically distinct from mental having 0 to 100 kilometers of silicates.
01:02
The next layer is called as a mental.
01:07
This mental layer is divided into upper.
01:12
Lower mental out of this the lower mental is slightly it is solid but this is magma which is solid molten in the molten state solidi liquidy it's kind of that and it it is to support internal stratification between the crust and the outer core it is chemically distinct from the crust and outer core the the mantle is not liquid however it is ductile or plastic sticky which means that on very long time scale at under pressure it can flow.
01:47
Then the third one is called as the core which is the innermost layer and the temperature of is very very high here and it is also solid in nature...
