Mountain biking is a type of cycling that involves riding specially designed bikes on rough, uneven terrain, such as hills, trails, and forests. It requires skill in handling obstacles like rocks, roots, and steep slopes. Mountain bikers use bikes with sturdy frames, wide tires with deep treads, and strong suspension systems to absorb shocks from bumpy surfaces. The sport can be done in various styles, including cross-country, downhill, and enduro, each with its own challenges and terrain types. Riders need to be physically fit and have good control over their bikes to navigate the demanding environments.

Rock climbing is an outdoor sport where individuals climb natural rock formations or artificial climbing walls. The goal is to ascend to the top of the rock or wall using both hands and feet while relying on strength, technique, and problem-solving skills. Climbers often use safety equipment such as ropes, harnesses, and metal clips to protect themselves from falling. The difficulty of the climb can vary depending on the route, the type of rock, and the climber's experience. Rock climbing is both physically demanding and mentally engaging, requiring balance, coordination, and endurance.

Snowboarding is a winter sport where people ride down snowy hills on a wide board that looks like a big skateboard. Riders strap both feet to the board, and do various tricks and moves like jumps, spins, and slides on different types of snow-covered ground, from mountains to special courses. While snowboarding riders need balance and coordination, and must know how to change their speed and direction in the snow. People snowboard for fun, to compete in freestyle events, or to race, as it is an exciting way to enjoy winter scenery.

Surfing is a water sport where a person rides a surfboard on the waves of the ocean. The surfer paddles out into the water, waits for a wave, and then uses the wave's energy to ride it back to shore. The goal is to stay balanced on the board while riding the wave, and surfers often perform tricks, turns, or stunts along the way. Surfing requires skill, balance, and good timing to catch the right wave. It is a popular activity enjoyed by people of all skill levels and can be done for recreation or in competitive events.
