What was the significance of Aristotle's work 'Meteorologica' written around 340 B.C.?
It represented the sum of knowledge on weather and climate at that time
Which statement about adiabatic processes is correct?
An adiabatic process occurs without any heat transfer to or from the system.
If the environmental lapse rate is greater than the dry adiabatic lapse rate, what is the atmospheric state?
Unstable
Which lapse rate is used to determine the cloud top height?
Moist adiabatic lapse rate
In a stable atmospheric condition, if a parcel of air is displaced vertically upward, what will happen?
The parcel will return to its original position.
What is the difference between the dry adiabatic lapse rate and the moist adiabatic lapse rate?
The dry adiabatic lapse rate is less than the moist adiabatic lapse rate.
In an unstable atmospheric condition, what happens to a parcel of air that is displaced vertically upward?
The parcel will continue rising indefinitely.
Which of the following is the most important characteristic of the adiabatic process?
The process occurs without any heat transfer to or from the system.
Which of the following conditions is necessary for a system to be in thermodynamic equilibrium?
The system must not be exchanging energy or matter with its surroundings.
Which of the following is the correct expression for the environmental lapse rate?
$\frac{dT}{dz} = -6.5^\circ C/km$
Which of the following is the primary function of Doppler radars in weather forecasting?

To provide a global view of cloud formations and their development.
Which of the following is the most accurate statement about the law of thermodynamics?
Energy can be transformed from one form to another, but the total amount remains constant.
