Snowboarding is the sport of sliding down snowy mountains while standing sideways on a single wide board attached to your boots. Unlike skiing, where you have two separate skis and face forward, snowboarders keep both feet strapped to one board and face sideways as they carve down the slope.

The snowboard itself looks something like a wide skateboard without wheels, with bindings that lock your boots in place. Snowboarders shift their weight and twist their bodies to turn, jump, and control their speed, almost like surfing on snow.

Snowboarding became popular in the 1980s and 1990s, when young people started bringing skateboarding tricks and style to the mountains. At first, many ski resorts banned snowboards, thinking they were too dangerous or just a passing fad. But snowboarding caught on so quickly that it became an Olympic sport in 1998. Today, millions of people snowboard at ski resorts around the world, performing tricks in terrain parks, racing down groomed runs, or exploring backcountry powder.

To snowboard is to ride a snowboard down a mountain. You might say you're going snowboarding this weekend, or that you snowboarded all day until your legs were tired.
