Extreme sports are any sport that involves great speed, height and danger. You need to be very fit to take part in these sports. It can be quite expensive because a lot of special equipment is needed. This type of sport is not usually a team sport like football or rugby. It is what is known as an individual sport because you are alone most of the time. BASE JUMPING: This is the sport of using a parachute(降落伞) to jump from fixed objects like skyscrapers, high towers, bridges, domes, statues and steep, high mountains. Base jumping can be very dangerous as you compete to be the quickest to reach solid ground. SKY DIVING: This sport also uses a parachute. Divers are taken up to a certain height in an aeroplane. They have parachutes strapped to their backs. They then jump out of the plane and freefall before opening their parachute at the correct moment. The parachute is to stop them from hitting the ground at a great speed, which would be very dangerous. The most important thing about this sport is knowing when exactly to open the parachute. ROCK CLIMBING: This is the activity of climbing up and down very steep rock formations. This sport needs special equipment to keep the climbers safe. A climber has to have great strength of body and mind. It is better to climb in small groups, so that there is someone to help in the case of an emergency.
