Answer:
The properties of the asthenosphere are:
1. highly viscous
2. mechanically weak
3. ductile region of the upper mantle of the Earth
In most cases, as altitude increases, the air in the troposphere cools. Vertical mixing occurs as a result of warm air rising. However, a layer of cool air may form beneath a layer of warm air on occasion. Temperature/thermal inversion refers to this deviation from normal temperature.
When an inversion occurs, polluted areas (such as London and Donora PA) experience unhealthy air and an increase in smog because pollutants are trapped at ground level rather than circulating away.
The answwer is b but not exactly
Earth's inner core is solid even though the temperature is so high because the pressure is also very high.
