1 Are raindrops tear-shaped? Diameter < 2 mm Diameter 2 – 5.5 mm Diameter > 5.5 mm

2 Diameter < 2 mm Water surface tension Air pressure Click to fall

3 Diameter < 2 mm water surface tension > air pressure retains spherical shape Air pressure Diameter 2 – 5.5 mm Diameter > 5.5 mm Click to fall

4 Diameter 2 – 5.5 mm Water surface tension Air pressure Click to fall

5 air pressure flattens bottom, top rounded hamburger bun shape Air pressure Diameter 2 – 5.5 mm Click to fall Diameter < 2 mm Diameter > 5.5 mm

6 Diameter > 5.5 mm Water surface tension Air pressure Click to fall

7 air pressure exceeds water surface tension breaks into small drops Diameter > 5.5 mm Diameter < 2 mm Diameter 2 – 5.5 mm Click to fall Air pressure
