The body of our planet consists of a number of concentric shells of different materials arranged in order of increasing density. There are similar concentric shells in the atmosphere above the surface of the earth but associated with the earth. The troposphere, which contains oxygen in a proportion suitable to sustain life on earth and clouds which give rain to the earth for (the provision of food, is in direct contact with the crust on which we live and from which we derive direct benefits. If troposphere and the crust, with which we are in direct contact are clubed as one layer, then we have the following seven concentric layers which may be the seven similar layers referred to in the verse under review:

7. Exosphere – Higher than 500 km
6 Thermosphere – 85 km – 500 km high
5 Mesosphere – 50 km to 85 km high
4 Stratosphere – 17 km to 50 km high
3 Troposphere – Sea level to 17 km
Crust – About 40 km deep
2 Mantle – About 40 Km to 3000 Km deep
1 Core – About 3000 Km to 6400 Km deep
