* Drag the correct answer into all target fields
Dr Mather refused to be daunted by this image. After all, the principle seemed plausible. Water droplets are swept up to the top of the clouds on updrafts, where they become supercooled (ie. although the temperature is below , the water remains liquid). When a supercooled droplet collides with an ice crystal, it freezes on contact and sticks. Successive collisions cause each ice crystal to more water droplets; the crystals grow until they become too heavy to remain in the atmosphere. As the crystals fall through the cloud, they become raindrops. The ice crystals act as frames to 'grow' raindrops.
