Atmospheric pressure is the pressure exerted bya)solidb)gases in airc)...
Explanation:
Definition of Atmospheric Pressure:
Atmospheric pressure is the force per unit area exerted on a surface by the weight of the atmosphere above it. It is caused by the gravitational attraction of the planet on the atmospheric gases.
Key Points:
- Atmospheric pressure is the pressure exerted by the Earth's atmosphere.
- It is a result of the weight of the air above a certain point.
- The pressure decreases with increasing altitude, as there is less air above to exert force.
- Atmospheric pressure is measured using a device called a barometer.
- The units commonly used to measure atmospheric pressure are millibars (mb) or hectopascals (hPa).
- Standard atmospheric pressure at sea level is around 1013.25 millibars or 1013.25 hectopascals.
Conclusion:
In conclusion, atmospheric pressure is the pressure exerted by the Earth's atmosphere. It is caused by the weight of the air above a certain point and is measured using a barometer. Atmospheric pressure decreases with increasing altitude. Therefore, option D, atmosphere, is the correct answer.
