T F 27) The Bergeron process is associated with supercooled clouds.

T F 28) At ‐15°C, clouds contain both ice crystals and supercooled water droplets.

T F 29) The large droplets in a cloud are the least likely to form precipitation.

T F 30) Both gravity and friction act to pull a raindrop to Earth.

T F 31) Freezing nuclei are part of the collision‐coalescence process.

T F 32) The Bergeron process may result in snow or rain.

T F 33) Atmospheric electricity is believed to play an import role in the collision‐coalescence process.
