the different depths of space as well as the Earth's sky.

If this second meaning of the word is considered, it is

stated in the verse that Earth's sky, that is, the atmos-

phere is made up of 7 layers. Of course, there can be
other meanings of the verse, but it is very interesting

that when we study the sky, we find that it is com-

posed of seven layers:

- Troposphere: This is the part closest to Earth's
- Troposphere:
surface. The thickness of this layer varies according to

the climates. The temperature drops as the altitude

increases, and the temperature at the highest altitude

is between -51°C (-60°F) and -79°C (-110°F).

- Stratosphere: The layer above the tropo-
- Stratosphere:
sphere. The temperature rises as one moves upwards.

- Mesosphere: The layer above the strato-
- Mesosphere:
sphere. Here, the temperature drops to -73°C (-100°F).

- Thermosphere: This is the layer above the
- Thermosphere:
Mesosphere. The temperature rises at a slower rate.

The temperature difference between night and day is

more than 100°C (212°F).

- Exosphere: The layer that begins at an altitude
- Exosphere:
of 500 kilometres (310 miles) above Earth's surface.

- Ionosphere: Gases in this region are found in
- Ionosphere:
ionic form. These ionised gases are what give the layer
its name.
