Answer:
Temperature
Step-by-step explanation:
The layers of the atmosphere are divided based on temperature differences.
Temperature is the degree of hotness or coldness of a body. Most of the temperature changes and differences originates from the radiated heat from the sun.
Atmosphere is the gaseous envelope round the earth.
These layers and their temperatures are;
- Troposphere 17°C to -51°C
- Stratosphere -51°C to -15°C
- Mesosphere about -15°C
- Thermosphere -120°C
- Exsophere about 1500°C
These divisions are premised on the temperature between the layers.
