Field hockey and ice hockey differ in several key aspects:
1. **Playing Surface**: Field hockey is played on grass, artificial turf, or indoor surfaces, while ice hockey is played on an ice rink.
2. **Equipment**: Field hockey players use a curved stick with a flat side and wear minimal protective gear, including shin guards and mouthguards. Ice hockey players use a stick with a blade and wear extensive protective gear, including helmets, pads, and skates.
3. **Ball vs. Puck**: Field hockey uses a small, hard ball, whereas ice hockey uses a rubber puck.
4. **Team Size**: Field hockey teams typically have 11 players, including a goalkeeper. Ice hockey teams have 6 players on the ice at a time, including a goalie.
5. **Game Duration**: Field hockey matches are usually 60 minutes long, divided into four 15-minute quarters. Ice hockey games last 60 minutes, divided into three 20-minute periods.
6. **Scoring**: In field hockey, goals are scored by hitting the ball into the opponent's net from within the shooting circle. In ice hockey, goals are scored by shooting the puck into the opponent's net from anywhere on the ice.
7. **Rules and Penalties**: Field hockey has rules like the "obstruction" rule, which prohibits blocking opponents with the body or stick. Ice hockey allows body checking and has penalties for infractions like tripping and high-sticking.
8. **Substitutions**: Field hockey allows rolling substitutions, meaning players can enter and exit the game freely. Ice hockey also allows frequent line changes during play.
9. **Global Popularity**: Field hockey is more popular in countries like India, the Netherlands, and Australia, while ice hockey is more popular in Canada, the United States, and Northern Europe.
