An instrument for measuring air pressure that consists of evacuated metal chambers very sensitive to variations in air pressure.
Angle of repose
The steepest angle at which loose material remains stationary without sliding downslope.
The total mass of a defined organism or group of organisms in a particular area or ecosystem.
Because the atmosphere is a complex interactive physical system, several different possible outcomes may result when one of the system’s elements is altered. These various possibilities are called climate-feedback mechanisms.
