Answer:
Hail.
Precipitation is also known as rainfall and it is important as a way of balancing and regulating the earths atmospheric conditions. Precipitation could involve rainfall, snow or hail.
Hail is usually accompanied by a storm which produces precipitation in the form of ice particles. This happens when the dew point is below freezing which results in the formation of ice crystals.
The "Cranes" is a short story book written by Hwang Sunwon. The story is set in Korea during the Korean War and focuses on two childhood friends, Songsam and Tokchae, who are on opposite sides during the war. Songsam has two flashbacks of his childhood memories with his friend Tokchae, where he remembers how they used to climb the trees and catch cranes. These flashbacks act as a reminder of the times he had spent with his friend and the importance of this friendship. As a result, these memories motivate him to let Tokchae free.
They use their resources and habitats around them to survive.
