A ramp is a sloped surface that connects two different heights, making it easier to move between them. Ramps are commonly used for accessibility, allowing people with mobility challenges to enter buildings or navigate spaces without stairs. They can be found in places like shopping malls, public transportation stations, and homes. Ramps come in various shapes and sizes, from small ones for wheelchairs to larger ones for vehicles. They are often made of materials like wood, metal, or concrete. By providing a gentle incline, ramps help ensure that everyone can access areas safely and comfortably.
