Visualizing Physical Geography Water in liquid and solid form that falls from the atmosphere and reaches the ground. Types: Rain drop greater than 0.5mm Precipitation Drizzle drop smaller than 0.5mm Occur mostly from stratus clouds Virga evaporating streaks of precipitation Collision/Coalescence process large droplets overtake and collide with smaller droplets in their path. Visualizing Physical Geography Precipitation Snow Sleet tiny ice pellets Freezing rain/drizzle Rime super cooled cloud or fog droplets freeze on contact in the belowfreezing air.
